Foamed lightweight soil has become an effective material to solve subgrade problems such as uneven settlement in the traffic field because of its advantages of light weight, high strength, good fluidity, and high construction efficiency. The traditionally foamed lightweight soil is mainly made of cement prepared by foaming. With a strong transportation network, carbon peaking, and carbon neutrality, foamed lightweight soil prepared using industrial solid wastes instead of cement has gradually become a research hotspot. Bayer red mud is one of the industrial solid wastes that are most difficult to reuse. Guided by the resource utilization of industrial wastes and the demand for green construction of traffic engineering, this study proposes to use Bayer red mud instead of cement to prepare foamed lightweight soil, and its application in traffic engineering construction has huge engineering value and ecological benefits. Aiming at the problems in the engineering application of red mud-based foamed lightweight soil, this study examined the regulation methods of the rheological properties of red mud-based foamed lightweight soil and revealed the effects of the water–binder ratio and superplasticizers on rheological properties and compressive strength of red mud-based foamed lightweight soil. The optimal water–binder ratio and optimal type and dosage of superplasticizers were determined, and the dynamic control of the performance of red mud-based foamed lightweight soil was realized. In this study, naphthalene superplasticizers significantly improved the fluidity of fresh slurry. The fluidity of the slurry increased with the increase in the water–binder ratio; when the water–binder ratio is 0.6, the fluidity of the slurry is too thick or watery. When the water–binder ratio is 0.5–0.6, the fluidity is between 165 and 212 mm, which is beneficial for construction. Both polycarboxylate and naphthalene superplasticizers can increase the fluidity of slurry. Naphthalene superplasticizers can increase the fluidity of slurry more remarkably, and the fluidity of 0.3% naphthalene superplasticizers increased from 165 to 176 mm when the water–binder ratio was 0.5. If the water–binder ratio is increased, the compressive strength first increases and then decreases. Polycarboxylate superplasticizers can weaken the compressive strength, whereas naphthalene superplasticizers can improve the compressive strength. An infrared spectrogram analysis showed that geopolymer gel is the main hydration product of red mud-based foamed lightweight soil, naphthalene superplasticizers can promote geopolymerization and increase the amounts of hydration products, and the optimum design values of the water–binder ratio and superplasticizers are determined.

The preparation process of soy hull nanocellulose hydrogel was optimized by Box-Behnken response surface. The structure and properties of soy hull nanocellulose hydrogel were studied. On the basis of single factor experiment, the preparation process of soy hull nanocellulose hydrogel was optimized through response surface with three factors and three levels when the maximum stress was used as the index. The structure and properties of soy hull nanocellulose hydrogel were characterized by Fourier transform infrared spectroscopy, X ray polycrystalline diffractometer, scanning electron microscopy, UV spectrophotometer, etc. The optimal process parameters were as follows: gelling temperature 191 ℃, freezing time 102 h, CaCl2 concentration 7%. Under this condition, the actual maximum stress of soy hull nanocellulose hydrogel was 84.11 kPa, which was close to the predicted value of 83.7 kPa. The nanocellulose of soy hull/sodium alginate/CaCl2 (SCNFs/SA/CaCl2) hydrogel showed uniform 3D network structure, excellent tensile performance (elongation at break was 220%), mechanical strength (83.97 kPa), transmittance (82%), and electrical conductivity (1.58 S/cm). The SCNFs/SA/CaCl2 hydrogel also had excellent mechanical strength and fatigue resistance after five cycles of stretching, so the service life of hydrogel was increased. This study provides a new method for preparing a tough, transparent, conductive and fatigue-resistant nanocellulose hydrogel.

Objective To explore the correlation between markers of tubular injury, 24 h urine protein quantification (24 hUTP) and albumin creatinine ratio (ACR) in patients with diabetic kidney disease (DKD) and explore the relationship between tubular and glomerular injuries to provide guidance for clinical management of DKD. Methods From November 1, 2019 to December 31, 118 proteinuric patients with a definite diagnosis of DKD at outpatient clinic and ward were recruited. And 24 hUTP, ACR, blood creatinine, urinary N-acety1-β-D-glucosaminidase, alpha 1 microglobulin, retinol-binding protein and kidney injury molecule-1 were measured and estimated glomerular filtration rate (eGFR) calculated by the CKD-EPI formula. Linear correlation analysis was utilized for examining the correlation between markers of proximal tubular injury, tubular reabsorption function and 24 hUTP and ACR. Results 24 hUTP at (0.5-3.5) g/24 h, urinary N-acety1-β-D-glucosaminidase, kidney injury molecule-1, alpha 1 microglobulin, retinol-binding protein were correlated linearly with 24 hUTP. The correlation coefficients (adjusted R2) were 0.192, 0.079, 0.054 and 0.040 respectively. Proximal renal tubular injury markers had the highest correlation with 24 hUTP. Urinary N-acety1-β-D-glucosaminidase, kidney injury molecule-1, alpha 1 microglobulin and retinol-binding protein were correlated linearly with ACR. The correlation coefficients (adjusted R2) were 0.367, 0.058, 0.077 and 0.076 respectively with the best correlation between proximal tubular injury markers and ACR. Conclusions In DKD patients, renal tubular injury markers are correlated linearly with 24 hUTP and ACR. Proximal tubular injury markers have the best correlations with 24 hUTP and ACR. Renal tubular injury is correlated closely with the progression of DKD.

Xylitol with different content (0%~25%) was added to glutinous rice flour to construct a xylitol-glutinous rice flour blend system to investigate the effects of xylitol on the gelatinization properties, thermodynamic properties, gel texture, rheology properties and digestion properties of glutinous rice flour, as well as on the quality of rice dumpling made from xylitol-glutinous rice flour. The results showed that the addition of xylitol increased the gelatinization temperature, peak viscosity and final viscosity of the xylitol-glutinous rice flour, while reduced the degree of short-range order of xylitol-glutinous rice flour. The xylitol-glutinous rice flour system behaved as a pseudoplastic fluid with shear thinning behavior. Compared with the control group, when the addition of xylitol was 10%, the xylitol-glutinous rice flour blend system had the smallest retrogradation value and gel hardness, which were 405 cP and 14.952 g, respectively. At this time, the content of resistant starch in the system was 29.88%, showing good retrogradation resistance. However, high content of xylitol (15%~25%) promoted the short-term regeneration of the xylitol-glutinous rice flour blend system, increasing its regeneration value and elasticity. Furthermore, the addition of xylitol significantly reduced the water loss rate and juice permeability of rice dumpling made of xylitol glutinous rice flour. Rice dumpling made of glutinous rice flour with 10% xylitol had high hardness, elasticity, resilience and chewability, and its eating quality was the best. This study provides a theoretical and technical references for the improvement of the quality of glutinous rice flour through xylitol and the product development of glutinous rice flour.

ObjectiveTo examine the prevalence of 23-valent pneumococcal polysaccharide vaccine (PPV23) vaccination and its associates among elderly people aged ≥ 65 years in Changshu city for developing immunization strategies on pneumonia prevention in the elderly. MethodsWith multi-stage random sampling, a face-to-face questionnaire survey was conducted among 2 402 elderly residents (65 to 84 years) recruited at 4 communities/towns of Changshu city during October 2021 – November 2022. The information on the participants’ PPV23 vaccination was obtained from the Jiangsu Province Comprehensive Vaccination Service Management Information System. Binary logistic regression model was used to analyze main influencing factors for PPV23 vaccination of the participants. ResultsAmong the 2 310 participants (96.17% of the elderly interviewed) with valid responses, 933 (40.39%) had PPV23 vaccination and 1 089 (47.14%) reported the willingness to have PPV23 vaccination. Logistic regression analysis showed that the elderly living far from urban central area, aged 70 – 79 years, not suffering from diabetes, and not utilizing air purifier at home or ventilation system in working place were more likely to receive PPV23 vaccination (P < 0.05 for all); while, the elderly with an average monthly income of 3 000 – 4 999 Chinese yuan, reporting poor general health, without the awareness of pneumonia vaccine, not intending or being unsure about to receive pneumonia vaccine, and washing hands more than 8 times per day with hand sanitizer or soap were less likely to have PPV23 vaccination (P < 0.05 for all). ConclusionThe PPV23 vaccination could be promoted among elderly people aged 65 years and above in Changshu city. The government and relevant health departments should take multiple measures from a practical perspective to implement free pneumonia vaccination for the elderly population.

Due to high-intensity mining and complex geological conditions, frequent occurrence of rock burst disasters in deep coal mines in China is posing serious threats to mine safety and efficiency. The insufficient locating accuracy of the seismic monitoring system in burst-prone coal mines is still presented, which leads to difficulties in accurately identifying and controlling coal burst hazards. To precisely characterize spatial evolution of seismic activities and reduce the impact of location error on the seismic pre-warning, this paper used the current seismic networks in burst-prone coal mines to conduct forward modeling experiments to explore the distribution characteristics of source location error vectors in the mining field. A new method for characterizing seismic fracture connectivity that considers location accuracy impacts was proposed and applied for coal burst pre-warning in a longwall face. The results show that significant vectorial differences of seismic source location accuracy at different area of the mining field is a key factor in false identifying coal burst risks. The proposed Fracture-connectivity-probability Index (\begin{document}$ F{_{{\mathrm{sum}}}} $\end{document}) characterizes the rupture scale by using the near-field radius that relates to the seismic energy level, which considers the locating error impacts on fracture connectivity between seismic sources at different distances. \begin{document}$ F{_{{\mathrm{sum}}}} $\end{document} can restore the distribution law of the fracture extension and connectivity probabilities of the coal-rock mass in the greatest extent, and it also corresponds well to the coal burst risks. \begin{document}$ F{_{{\mathrm{sum}}}} $\end{document} can balance forecast accuracy and recall rate and have better correlation with coal burst, which can be an ideal indicator for periodical coal burst risk assessment. The outcome of this research can provide references for evaluating the monitoring capability of seismic networks and improving the ability and efficiency of coal burst pre-warning and prevention.

Objective To explore the effects and mechanism of resistin-like molecules α(also known as FIZZ1) on the ability of mouse aortic endothelial cells to form new blood vessels. Methods Mouse was stimulated by FIZZ1 at 10 nmol/L,20 nmol/L and 40 nmol/L.The role of FIZZ1 in endothelial cell migration and blood vessel formation was verified by using endothelial cell tube formation experiments and endothelial cell migration experiments in vitro;The effect of FIZZ1on signaling in mouse aortic endothelial cells was detected by high-throughput sequencing,and pathways with significant differential expression signaling were selected. Results Under different concentrations of FIZZ1,the area of blood vessel formation in mouse aortic endothelial cells gradually increased,and 40 nmol/L FIZZ1/ RELMα had the strongest effect in promoting angiogenesis.With the increasing concentration of FIZZ1,the number of endothelial cells migrated increased,and the migration capacity gradually increased.A total of 1 253 genes were found to be differentially expressed,including 427 up-regulated genes and 826 down-regulated genes.The mechanism may be related to the significant expression difference of COL1A1,FLT 4 and ITGA 3. Conclusion FIZZ1 can induce neovascularization of mouse aortic endothelial cells in vitro,and its mechanism may be related to significant differences in gene expression such as COL1A1,FLT4,and ITGA3.

Analysis of water balance in the middle reaches of the Yellow River is important for the effective water resources management, ecological protection, and high-quality development in the Yellow River Basin. The Qinhe River Basin, located at the end of the middle reaches of the Yellow River, has serious water problems, such as, river interruption and insufficient inflow into the Yellow River, due to the implementation of the upstream water diversion policy and the increase in domestic and industrial water use. To address the water problems, the water resource demand, water supply capacity, and supply-demand balance of the basin were analyzed based on the ecological water demand. The results show that (1) the spatial distribution of water supply and water demand in the Qinhe River basin is heterogeneous. All the upstream river reaches in the Shanxi Province are able to guarantee the ecological water demand in the river channel, while in the downstream Henan Province, only the minimum water demand can be met; (2) the total suppliable water resources in the Qinhe River basin is 10.04×108 m3, and the sum of industrial, domestic, and ecological water use outside the river channel is 8.89×108 m3. The remaining water in the river channel is only 1.15×108 m3, which can only meet the minimum ecological water demand; (3) the amount of surface water used by industrial production and life in the basin will be 6.98×108 m3 in 2030, and the total amount of water use will be 9.81×108 m3, resulting in that the remaining water cannot support the minimum ecological water demand. We pose five suggestions for the water problem in the Qinhe River Basin: Reducing the industrial water consumption, improving the water utilization rate of agricultural irrigation, promoting water conservation technologies with high effectiveness, and improving the ecological environment. This study can provide basic information for the effective water resources management in the Qinhe River basin.

ObjectivesA crankshaft is a key component of marine diesel engines. In order to monitor crankshaft stress and ensure the safe and reliable operation of ships, a crankshaft stress monitoring method based on digital twin technology is proposed.MethodsBased on the digital twin concept, a framework for the intelligent operation and maintenance of marine diesel engines is put forward. Taking a certain type of in-line 6-cylinder marine medium-speed diesel engine as the research object, a digital crankshaft health condition assessment system is developed on the basis of available data from real engines. First, based on an RBF neural network, the cylinder head vibration acceleration signal is used to identify in-cylinder pressure, then the load of the crank pin is calculated. Based on the finite element method, the key positions which affect the lifecycle of the crankshaft are obtained after analyzing its stress and fatigue. A BP neural network is used to evaluate the stress of the crankshaft after a reduced-order model of forces and stresses is used to determine real-time performance. A BP neural network is then used to evaluate the stress of the crankshaft.ResultsThe prediction errors of the cylinder pressure and crankshaft stress of the proposed model are both less than 5%, and the stress prediction time is shortened to the second level, realizing the real-time/quasi-real-time update of the twin model.ConclusionsThe results of this study show that it can be used as a new reference for the real-time monitoring and intelligent operation and maintenance of diesel engine components.

[Introduction] The increasingly high proportion of renewable power sources raises higher requirements for the safe and stable operation of the power system and the reliable supply of electricity. Hydrogen and electricity are complementary in many scenarios of energy consumption. Green hydrogen produced by renewable power will become an important component of the new energy system, which can also facilitate the construction of the new power system. Recently, green hydrogen demonstration projects in China and abroad are burgeoning. However, the typical modes and future development trends are not clear. This paper aims at clarifying the typical modes for green hydrogen projects and providing solutions to issues faced by the large-scale application and the full play of power-hydrogen coupling. [Method] In this paper, the existing green hydrogen demonstration projects in China and abroad were systematically analyzed. The characteristics of the three groups were studied, based on which, the development trends of green hydrogen demonstration projects were proposed. Then, the key problems and challenges were analyzed, and key measures were proposed. [Result] Through the study, the green hydrogen projects are grouped into three categories, which are power-hydrogen coupling projects on the distribution/micro-grid side, large-scale hydrogen production near renewable basis and utilization projects and hydrogen-based flexible adjustment projects. Key issues lying ahead include the lack of coordinated planning between the power and hydrogen system, the less economic competitiveness of green hydrogen and some of the key technologies, equipment and materials are dependent on imports. [Conclusion] To solve these issues and promote the development of green hydrogen projects, the coordinated planning of power and hydrogen system should be strengthened, formulated a set of supporting policies, improved the relevant market mechanisms, accelerated the standards and deployed some essential projects.

To address the situation wherein an enemy submarine maneuvers in an unknown course when an anti-submarine surface ship is called, a genetic algorithm-based submarine search method is proposed. The method combines the ship sonar detection model, enemy submarine target motion model, ship search motion model, and search path discovery probability calculation model. It introduces information confidence into the discovery probability calculation model, which enhances its reliability. Subsequently, a genetic algorithm is used to solve the optimal heading angle and speed of each section of a single ship and double ships in the on-call search process, and the optimal paths of single and double ships on call spiral search are determined. Finally, the variation law of the discovery probability of searching the target is formulated under the conditions of changing only the heading angle and changing both the angle and speed of single and double ships. The results indicate that, compared to the traditional spiral algorithm, the ship search mechanism with increasing change speed is more flexible and can improve the discovery probability. When the search force is sufficient, using a multiship formation search can significantly improve the discovery probability. The results provide a tactical reference for surface ship searches and submarine attacks.

【Objective】The new urbanization strategies provide new opportunities for farmers to increase their income, and adjusting its action path according to the specific impact of the new urbanization can promote the growth of farmers' income more effectively.【Method】Based on the urban panel data of the Pearl River Delta region from 2010 to 2021, the kernel density estimation was used to analyze the dynamic evolution trend of farmers' income, and the fixed-effect model was used to empirically analyze the impact effect of the new urbanization level on farmers' income.【Result】The results show that during the research period, the farmers' income level in the Pearl River Delta region has increased significantly, the sources of farmers' income are diversified, income from wages and salaries is still the main component, income from property such as housing rental has been an important source, the absolute gap between farmers' income levels between cities is expanding, and the income levels between the urban areas spread to the high value area and the spatial agglomeration characteristic is obvious, and the economic urbanization has the strongest effect on farmers' income. However, at present, the new urbanization development in the Pearl River Delta region still has some problems, such as low quality of urbanization, mismatch between supply and demand, large income gap between urban and rural areas, and shortage of land resources.【Conclusion】It is suggested that when pushing the people-centered urbanization strategy in the Pearl River Delta cities. it should focus on improving the quality of urbanization of agricultural migrants and promoting the integration of agricultural migrants into cities; insist on optimizing the local industrial structure, vigorously developing non-agricultural industries such as modern service industry, and creating more jobs to maximize the farmers' income effect of urbanization.

Reservoir strata with carbonate rocks of Feixianguan Formation are the main output horizons of natural gas in Puguang Gas Field, Northeast Sichuan. As to the division of four members of Feixianguan Formation, the controversy regarding whether the T1f1 member and T1f2 member should be classified in the same third-order sequence appears. Based on the core observation of the existing drilling in Puguang area, the karst breccia section is found atthe middle of the T1f1-T1f2 section, and there is a certain lithologic interface above and below it. The bottom of T1f1 is fine-grained dolomite. From the top of T1f1 to T1f2, oolites and mould casting holes begin to develop.The carbon and oxygen isotope study in Well PG104-1 shows that the fluid environment is atmospheric freshwater fluid, which proves the development of quasi-syngenetic karst, while the oxygen isotope value is more than -5‰, indicating that the relevant fluid is atmospheric freshwater fluid, which proves that the bottom of the karst breccia section experiences a certain period of exposure and that a sedimentary discontinuity appears.Considering the differences in carbon and oxygen isotopes between the upper and lower interface, the emergence and disappearance of die casting holes and the changes in logging curves, it is considered that the boundary between T1f1 and T1f2 can be distinguished and characterized by karst breccia sections. This study provides an important basis for the study of the storage and migration of oil and gas in Feixianguan Formation.

The application markets for portable electronics, battery-operated electric vehicles, and large-scale energy-storage grids have been expanding rapidly for the past ten years, which has attracted massive attention to the investigation and development of batteries with high energy density, long cycle life, high safety, and low cost. A commonly used lithium-ion battery consists of intercalation-type materials, such as LiCoO2 as cathode and graphite as an anode. Owing to technical difficulties, including high cost, low stability, and the poor safety of Li, the large-scale application of the high-energy Li anode is still premature. A more common strategy than the one mentioned above for improving the energy density of Li-ion batteries is to develop a cathode material with high specific capacity and low cost, such as LiNi1–x–yCoxMnyO2 (NCM) and LiNi1–x–yCoxAlyO2 (NCA). Among the NCMs and NCAs, Co is more expensive and less abundant than Ni, Mn, and Al. Presently, high-nickel, low-cobalt NCMs, and NCAs have attracted huge attention as suitable cathodes for both academic and industrial purposes. LNiO2 can be regarded as the Ni content increasing to 100% for NMCs and NCAs, which stood as the “holy grail” of layered cathodes. This study aims to investigate the structural and electrochemical stability of LiNiO2 and B-doped LiNiO2. In this study, Ni(OH)2 was synthesized by a coprecipitation method using a continuous stirred tank reactor (CSTR). LiNiO2 and B-doped LiNiO2 were synthesized by high-temperature solid-state sintering. The crystal structure, surface morphology, and electrochemical performance were investigated by X-ray diffraction (XRD), Rietveld refinement, scanning electron microscopy (SEM), constant current charge–discharge, cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). XRD and Rietveld refinement results indicate that B-doping could slightly increase the lattice parameters and unit cell volume due to the occupancy of B in the tetrahedral site. Meanwhile, the LiO6 slab distance increases, consequently favoring the transportation of Li+ during (de)-intercalation. SEM images suggest that LiNiO2 and B-doped LiNiO2 consist of primary grains with a similar size, and the secondary particle in both samples has an average size of 10 µm. Long-term cycling data show that B-doping could improve capacity retention. The capacity retention at 40 mA·g−1 is 77.5% for the B-doped sample, whereas a value of 66.6% is obtained for LiNiO2. The dQ/dV vs V curves and EIS results suggest the suppression of impedance growth by B-doping.

Due to the lack of communication mechanism between inter-blockchain services, it is difficult to formulate effective interconnection between different blockchain.Under the smart services ecosystem, two parties of the transaction not only execute the single transaction of data assets, but also extend the scope of their services to cover a wider range of digital assets transfer scenarios.An inter-blockchain communication(IBC) framework for smart service transaction is designed.With component-based and modular design, it makes flexible for the subject and object application of smart service transaction to access IBC framework and thus promote inter-blockchain scalability.Finally, a three-phrase inter-blockchain communication protocol for smart service transaction is proposed to ensure the atomicity and consistency of inter-blockchain ecosystem.

The decentralized cryptocurrency which was based on block chain has been thought the most successful one in history.In the system,public keys were used as the users’ accounts which guaranteed the anonymity in real transactions.However,all the transaction information was recorded in the block chain,it was a potential threat for users’ privacy which might leak the payment information.Moreover,to avoid double-spending,it was agreed that the transaction on the target block was valid only if another k blocks were generated after the target one.The long waiting time reduced the efficiency of the payment system.A model of payment system based on a proxy-cryptocurrency was proposed,and a solution based on blind signature techniques was proposed.The scheme introduced a proxy in the payment phase,by which transaction confirmation time could be reduced and the transaction efficiency could be improved.Meanwhile,the system implements better anonymity,namely as the privacy protection function.

In order to improve the accuracy of recommendation, especially the matrix score of personalized recommendation technology is too spars, a new recommendation algorithm was proposed. The advantages of this algorithm were mainly embodied in the following aspects. Firstly, the improved algorithm with RFM model was used to select the original customer in some condition, making the recommended source of data more accurate and efficient. Secondly, in the improved algorithm the customer consumption history records were filled to the matrix to improve the consistency of the matrix of score. Thirdly, the traditional Pearson similarity calculation formula was improved to make the search of target users of similar neighbor more accurate. Then the simulation experiment was carried on by using the improved algorithm. It can be proved that the improved algorithm is better than the traditional one in accuracy. At last, the improved algorithm was applied to a recommendation system with personalized recommendation function. It was shown that the recommendation algorithm was efficient and valid.

In this study, 1626 patients with severe craniocerebral trauma were assessed by Glasgow Coma Scale (GCS, 886 patients of 3-5 score and 740 of 6-8 score). Patients were divided into 2 groups. Ninety hundred and eleven patients (496 of 3-5 score and 415 of 6-8 score) underwent hemisphere calvarial bone flap decompression with auxiliary mild hypothermia (experiment group), and 715 patients (390 of 3-5 score and 325 of 6-8 score) underwent traditional frontal, temporal, parietal large traumatic craniotomy (control group). After operation the treatment of 2 groups was basically the same. Compared with control group, the intracranial pressure of experiment group on the 1st, 3rd, 5th and 7th days after surgery decreased significantly (P < 0.05, for all); the consciousness recovery time was significantly shorter (P < 0.05, for all); the prognosis after 3 months was better (P < 0.05, for all). Hemisphere calvarial bone flap decompression with auxiliary mild hypothermia treatment could significantly reduce the morbidity and mortality, and improve the quality of life and prognosis of patients with severe craniocerebral trauma.

In order to verify the protocol conformance of radio resource management（RRM）cell reselection in TD-LTE system，a new testing method was designed by implementing testing and test control notation version 3 （TTCN-3）abstract test suit.Furthermore，the test suit was operated on the TTworkbench developed by German Testing Tech.The graphical presentation format（GFT）and test report to check the protocol conformance of cell reselection were generated.The scheme has been successfully applied in the project development of TTCN extended testing set instrument（RRM part）in TD-LTE system.

The 2-D time-stepping finite element method is adopted to systematically analyze the effect of slot opening on motor parameters like electrical leak age reactance, power factor, winding current and air gap flux density of high power surface mount type PMSM which is driven by inverter. Thereby, the effect of slot opening on eddy current loss in permanent magnets is determined. Analysis shows that while the width of slot opening decreases, the leakage reactance increases. Thus the ripple current caused by PWM wave is effectively restrained and the higher harmonic current is effectively filtered. In consequence, the amplitude of the high order harmonic components of air-gap flux density reduces, leading to the decrease of eddy current loss in permanent magnets. Meanwhile, through the temperature-rise test of permanent magnets of two different PMSMs with different slot openings, the validity of this analysis method and results are proved.

Beijing Olympic Games is not only the large-scale international sport event, but also a way for the world to know about China. Although the 2008 Beijing Olympic Games have been held, the research of Western Media news framework on Beijing Olympic will help to know about Chinese National Image Communication nowadays. Moreover, it will also help to think about how to broadcast Chinese National Image after the Beijing Olympic Games. For these purposes, the research focused on the news framework and national image by analyzing the Beijing Olympic reports of New York Times and The Times. Using content analysis, the article analyzed the characteristics and cause of the news frameworks in order to provide a solution for Chinese National Image Communication. After research, this paper found that New York Times and The Times both have 12 news frameworks to coverage the Beijing Olympic. They both paid high attention on the "Olympic framework", "Tibet issue framework" and "Human Right framework". As these two newspapers still have different background and media concepts, they paid different attention to some news frameworks, such as "Darfur framework"and "Media Freedom framework". In addition, this paper also analyzed the people who talked about their opinion in the news and found that officials and non-governmental organizations have more right to speak to media. After analyzing, this paper found that both newspapers' frameworks were affected by the impact of political and ideology system, national and interests' groups, media characteristic and the thoughts of Cold War. In order to broadcast Chinese national image, the paper designed a Chinese National Image Communication Model which was inspired by Gruning's mixed motive model. On the one hand, the model lets western public know about China through the effects of Chinese government, Chinese media and Chinese opinion leaders. One the other hand, the model lets China know about west by knowing the characteristics of western public, western media news frameworks and western opinion leaders. Using these methods, China can eventually establish a good national image in the world by pushing China and west to the win-win region.
