The Ordovician fissure-cavern carbonate reservoirs of Tarim Basin have relatively large production thickness, long completion intervals and serious heterogeneity problems, former studies about physical parameters for fractured intervals of acid fracturing cannot be well presented through mean algorithm method. This paper uses mean square deviation method to acquire the values of the main influencing factors of acid fracturing, then optimizes the physical characteristics of the fractured intervals. The BP neural network simulation has been adopted to get the optimal BP neural network structure model. In Tarim, this study has simulated 20 wells before acid fracturing using the decision software which compiled by the optimum neural network construction. Comparative analysis has been made through application examples, the coincident rate of mean algorithm is 75%, compared with the 90% of mean square deviation method. Therefore, during the target selection for acid fracturing of heterogeneous carbonate reservoirs with long open hole intervals, it’s significant to use mean square deviation method to optimize physical parameters of reservoirs.

A renovated hybrid membrane bioreactor (HMBR) was investigated for its capability of coking wastewater treatment. The HMBR combined biofilm process and membrane filtration process. The system was efficient in degrading COD and phenol in coking wastewater and controlling membrane. It was found that the coking wastewater could be effectively treated with 88.6% of COD removal efficiency and 98.3% of phenol removal efficiency at hydraulic retention time (HRT) of 16 h. The removal efficiency of COD and phenol decreased gradually down to 83.2% and 97.7% when HRT decreased to 8 h. The long term experiments indicated that the degree of membrane fouling for HMBR was far lower than that for MBR. The scrubbing effect of suspended carrier in HMBR was observed to be capable of reducing the cake fouling of membrane. The operation time of HMBR was 8.4-fold longer than that with MBR.

Based on methods of the fuel consumption, statistical and analogy analysis, the throughput amount method was established to calculate the emissions from port handling, and the minimum mileage method was established to estimate emissions from port cargo highway distributing. In the methods, some coefficients were used obtained by investigations: the current container handling emission factors of NOx, VOCs, CO, PM2.5 and SOx are 1.64, 0.21, 0.42, 0.01 and 0.29 t/TEU; the energy consumption of the unit throughput is 4.12 tons of standard coal per 104tons; the ratios of the unit non container cargoe handling energy consumption for coastal and inland river ports to those of container cargo are 0.631 and 0.405; the ratio of the unit non container cargoe highway distributing energy consumption to those of container cargo is 0.365. The calculation results show that the total emissions from the cargo handling and highway distributing of 2013 in China for NOx, VOCs, CO, PM2.5 and SOx are 54.365, 14.821, 24.631, 5.599 and 16.802 104tons, and the emissions from highway distributing are 4.21, 10.02, 8.24, 8.22 and 8.19 times of the emissions from port handling facilities. According to energy saving and emission reduction measures, formulas were established to calculate air pollutant emissions after the new added measures. Analyzing the real performance of the measures implemented since 2001 and predicting its trend of development, a scenario was designed, in which the Chinese port throughput continuously rises while the energy saving and emission reduction efforts gradually increase by 2020: the popularities of the energy saving measure of "oil changing to electricity" and the clean fuel measure of "oil changing to gas" reach 100% and 83%; the proportion of power plants with 95% desulfurization and denitrification reaches 100%; the energy saving and emission reduction efficiency of port cargo distributing optimization measures reaches 40%. Under this scenario, the prediction shows that during the port throughput increasing approximately 4.2 times from 2005 to 2020, the air pollutant emissions will be reduced significantly, returning to a lower level compared with 2005. The above methods and results can be used to support the decision-making and the implementation of emission reduction measures for the national, regional and port enterprises.

Batch experiments were carried out to investigate the effect of solution pH on the adsorption as well as adsorption kinetics and adsorption isotherm. The results show that at pH 2, obtain the maximum removal rate. The adsorption data were better fitted for the Freundlich model,indicating that the adsorption of Cr (VI) preferably follows multilayer and heterogeneous adsorption process. Compared with two kinetic models linear fitting parameters, adsorption conforms to pseudo secend-order kinetic model well,revealing chemisorption as the dominant mechanism.

Mechanical properties of CA mortar with different air content were studied, and the size of the air bubbles was also analyzed. Results showed that the ductibility of CA mortar could be largely prolonged by the air bubbles. As the air content of CA mortar increased from 4.2% to 9.1%, the strain of the maximum stress increased from 1% to 2%. The compressive strength and elastic modulus of CA mortar decreased as the air content increased. And when the air content of CA mortar was higher than 15%, the compressive strength of it decreased rapidly. The SEM analysis showed the air bubbles of diameter larger than 0.5mm was the primary reason of decrease of the compressive strength.

With its unique structure and properties, polymer surfactants have been used in chemical flooding. Compared with ordinary polymer, polymer surfactants have a higher recovery degree. However, remaining oil starting mechanism in different pores using different polymer surfactants after water flooding is still unclear. NMR (Nuclear Magnetic Resonance) has a good effect on determination of rock oil saturation and analysis of pore structure. In this paper, oil displacement experiment using kerosene which contains no hydrogen was conducted and the problem caused by the similarity between oil phase relaxation time and water relaxation time in large pores was overcome. Through the change of NMR relaxation time, oil distribution situation in different pores of ordinary polymer, refining III polymer surfactant, and Haibo III polymer surfactant after polymer flooding was measured accurately. This paper also quantitatively analyzed the contribution degree to oil recovery in pores of different sizes, and evaluated oil displacement effect of the above three kinds of oil displacement systems. The results show that when only the swept volume is considered, recovery degree of Haibo III polymer surfactant is higher, reaching 53.66%. In different systems, middle pores contribute most to recovery degree. At the same time, the remaining oil in middle pores and large pores accounts more, which is the main attack direction towards tapping the potential of remaining oil in the oilfield.

The magnetic FeCoGd thin films with various sputtering power from 10 to 30 W were fabricated on glass substrates by magnetron co-sputtering. The crystal structure of as-deposited FeCoGd thin films was investigated by X-ray diffraction. And an increasing trend of grain size with the increasing sputtering power was shown. When sputtering power is below 30 W, the films exhibited obviously in-plane uniaxial magnetic anisotropy, and the in-plane magnetic anisotropy field Hkdecreased with increasing deposition power. Moreover, good high frequency characteristics were obtained. The magnetization reversal mechanism has been investigated via the in-plane angular dependences of the magnetization and the coercivity. The experimental data points indicated that the magnetization reversal mechanism of FeCoGd film with in-plane uniaxial anisotropy is domain-wall depinning and coherent rotation when the applied field is close to the easy axis and hard axis, respectively. A spin reorientation transition phenomenon was observed when deposition power is larger than 30 W. A stripe domain structure for the sample with 30 W deposition power was developed due to a dominated perpendicular magnetic anisotropy.

The winter protection of biological species is important in many kinds of fruit production in North China. Environment techniques for overwintering cultivation of summer-bearing, fall-bearing red raspberry and blackberry were studied on open field and large plastic tunnels by analysis of growth and development of raspberry under three kinds of treatment method. The result showed that the shoots death rate was 100% on open field. But, the all shoots survived in other two treatments. The survival percent of seedling was over 90% in all treatments, the survival percent of blackberry was more than red raspberrys. There was not any germination of floricane on open field. The floricanes in plastic tunnels germinated 20-25 days earlier than mounding soil treatment. The germination of primocane on open field was 17-18 days later than in mounding soil and 34-40 days later than in plastic tunnel. The length of primocan on field including mounding soil and planting on open field was shorter than plants in tunnels at the same time. No. 47 black berry grew most rapidly in plastic tunnels among all treatments. The fruit yield per cane on open field was lowest among all cultivar, next was in mounding soil. There was no difference in fruit weight between different treatments of cold protection. The weight of No.47 black berry was around 2-3 times more than other cultivars in all treatments. The yield and fruit weight of raspberry were lower than other place including them in plastic tunnels. Therefore, the raspberry plants in plastic tunnels may live through winter better in dry and cold area without artificial heating. Mounding soil also is simple and good and economic method for its cold protection.

In this study, sewage sludge samples were collected from 25 wastewater treatment plants (WWTPs) in Shanghai, and free and bound PBDEs were extracted in different ways. The concentrations of free and bound PBDEs were in the range of 111.69 to 13119.59 ng/g dry weight (dw) and 4.30 to 60.17 ng/g dw, respectively. BDE209 were the dominate congener and the concentrations of free and bound BDE209 ranged from 89.64 to 12424.84 ng/g dw and 0.85 to 44.00 ng/g dw, respectively. The concentrations of bound PBDEs were quite stable, indicating bound PBDEs werent high related with the input of total PBDEs. The fractions of bound PBDE congeners increased with the numbers of Br atoms, which suggested that PBDE congeners with low molecular weights were more prone to desorb from micro-pores of organic matters in sewage sludge. The fractions of bound PBDEs in total PBDEs were in the range of 0.16 to 22.73%, suggesting bound PBDEs played an important role in farmland soils after sludge application.

The widely use of phthalate esters (PAEs) in both industry and commercial products leads to their ubiquitous existence in the environment. In this study, sewage samples were collected from Several wastewater treatment plants (WWTPs) in Shanghai, China to investigate the levels and profiles of PAEs. Of the 16 PAEs, DMP, DEP, DnBP, DiBP, DCHP, DEHP, DnNP and DnOP were present in all sludge samples. DEHP and DnBP are found to be the dominant PAEs in sludge, and the average concentration of DEHP in this study is at a medium magnitude in the world. Following sludge application in farmland, the annual mass loading of PAEs is up to 32,000 kg. However, further studies are needed to explore the metabolites of PAEs in sludge since they are easily biodegraded in WWTP process.

To investigate the transfer of PBDEs from products into the aqueous media, experiments and analysis were carried out by contacting TV housing plastics with distilled and dissolved humic solution (DHS) in brown bottles in the artificial climate box. The leaching test conditions were a liquid-to solid ratio of 100:1, and a contact period of 1, 2, 4, 7, 10, 13, 16 and 20 day (s), with pH of 3, 5, 7, 9 and temperature of 15, 20, 25 °C. The leaching concentrations of PBDE increased with DHS rather than distilled water, and were found to be remarkably enhanced when TOC of DHS increased. Despite no detection of most of the lower BDEs in distilled water, most homologues could be detected in DHS, and their solubility increased according to the contact time; those of highly BDEs increased to 10 times their maximum solubility in distilled water. Temperature had limited influence for the limited range investigated. Lower pH generally resulted in higher transfer of PBDEs to aqueous phase.

In this paper, two shortcomings of standard ART2/ART2A algorithm were revealed through theoretical analysis: (1)Standard ART2/ART2A algorithm is only suitable for the case in the nonnegative real number field because of a limit of pretreating process in F1layer; (2)Even through all input patterns are shifted to the nonnegative real number field through coordinate transformation, the standard ART2/ART2A algorithm can not correctly recognize those patterns which have same phase, but different amplitudes. As a result, the standard ART2/ART2A algorithm is not quite suitable for universal pattern recognition. So this paper presented a new nonlinear transforming function in F1layer and a new competitive learning formula in F2layer for traditional ART2/ART2A algorithm. The applicable scope of the new ART2/ART2A algorithm is expanded to entire real number field from nonnegative real number field. The result of typical calculation example shows that the presented algorithm is effective.

Greedy algorithms represented by orthogonal matching pursuit (OMP) and subspace pursuit (SP) algorithms are practically used in image processing based upon compressed sensing theory. However, there are two disadvantages: 1)Relatively poor signal reconstruction accuracy; 2) High computation complexity and measurements time. This paper proposes a frame of greedy algorithms obtaining a novel fusion of matching pursuit (FMP), combining the OMP and SP algorithms. FMP unites the two support sets from OMP and SP selecting the most appropriate atoms to achieve secondary screening of the original two support sets, finally realizing the accurate signal reconstruction. Using same test conditions, image reconstruction experiments and stability of Frame, the proposed FMP algorithm can effectively improve signal-to-noise ratio (SNR) with improved reconstruction error. Reconstruction effects using proposed FMP are better than separately using other two greedy algorithms for both high and low resolution images.

It was observed that more amount of celluase protein bound on the cotton would result in higher backstaining, indicating the direct adsorption between cellulase and indigo. It was also found that smaller indigo particle could generate higher backstaining because of its bigger specific area. At last, nonionic surfactant AEO-9 and protease were added to investigate their ability to remove backstaining. It was concluded that both of them could reduce the backstaining efficiently.

Following strategies of Coastal Open Go West and Reviving Northeastern Old Industrial Base the state put forward the strategy of Rising of Central China in order to promote its rapid development. Urban agglomeration in Central China is becoming academic focus with unprecedented development momentum. It applies multidisciplinary theory of human geography, regional economics, etc. and takes urban agglomeration of Hunan, Henan and Hubei provinces for example to empirical analysis. Firstly, analyzing the historical evolution, urbanization space development and patterns then comes to spatial association of urban and rural through comparison, Finally, showing the development characteristics of urban agglomeration in Central China and putting forward urbanization suggestion.

In order to maintain habitats status and prevent the degradation of ecosystems, the ecological water requirement should be considered in the plannings, especially for the arid and semi-arid regions. In this paper the effect of the Planning for Protection and Utilization of Luyanghu Wetland on the ecological water requirement of Luyanghu wetland was analyzed. The results indicated that the ecological water requirement in the planning was far more than the actual quantity which will intensify the severity of the local water shortage without suspicion. At last it was advised to apply the method of ecological benefit evaluation to deciding the best feasible scheme for the best ecological benefit.

The band structures and magnetic properties of Heusler alloy Cr2ZrGe with Cu2MnAl -type have been investigated by first-principles calculations. The alloy is predicted to be close to half-metal ferromagnet. The alloy has a total magnetic moment of 3.98μB per unit cell on first-principles calculations which is in agreement with the SlaterPauling (SP) rule. The magnetic moments of Cr(A) atom and Cr(C) atom which are both much larger than that of atom Zr(C) are same. This similarity comes from similar atom coordination surroundings of Cr(A) and Cr(C) atoms in crystal structure.

Highly crystalline FeWO4 nanoparticles (NPs) were synthesized via the hydrothermal synthesis method while amorphous FeWO4 NPs were prepared by the room temperature precipitation method. It was found that a dissolution-recrystallization process appeared due to the Ostwald ripening when room temperature precipitates undergo the hydrothermal process. Photocatalytic performance toward the degradation of methylene blue showed that crystalline FeWO4 NPs displayed a higher activity than amorphous samples, mainly ascribing to the substantial elimination of defects after crystallization because the defects promoted the recombination of electron-hole pairs.
