Due to the thin-walled wind-sensitive structures of large crude oil storage tanks, it is necessary to consider the wind load failure of oil storage tanks in coastal areas under strong wind conditions during the design process. Based on the finite element analysis software ANSYS\Workbench, the static structure analysis and buckling analysis of the 100, 000 cubic crude oil storage tanks are carried out. In order to solve the buckling failure phenomenon, a wind-resistant ring structure was optimal designed for the crude oil storage tank according to standards, so that the storage tank can withstand hurricanes and typhoons above level 12 with a wind speed of 137 km/h.

The inherent dangers of the petrochemical industry and the extreme meteorological conditions in the coastal areas make the island-type petrochemical parks have complicated safety hazards. In order to improve the safety management capability of my country’s island-type petrochemical parks, this paper analyzes the risk sources of the island-type petrochemical parks from the four subsystems of human, machine, environment and management, and uses the network analytic hierarchy process (ANP) to calculate the correlation weights between the indicators. The establishment of an evaluation model for the safety level of island-type petrochemical parks and quantitative analysis of the safety level of island-type petrochemical parks are of great significance for guiding the safety work of my country’s island-type petrochemical parks.

The object is to explore the clinical effect of applying Yiqi Tongnao Decoction in the treatment of patients with acute cerebral infarction of Qi deficiency and blood stasis. In this study, patients in our hospital were taken as the main research objects, all of whom were patients with acute cerebral infarction of Qi deficiency and blood stasis type. The number of patients is 100. The study period is from January 2020 to January 2021. The 100 patients selected for this study are divided into two groups. One group is given conventional western medicine treatment as the control group, and the other group is given Yiqi Tongnao Decoction treatment as the experimental group, the therapeutic effects of the two groups of patients were compared and analyzed. The scores of various TCM syndromes of the experimental group were lower than those of the control group, and the scores of neurological deficit and blood viscosity after treatment were lower than those of the control group. The effective rate of treatment was 94.00%, which was higher than 78.00% of the control group. The adverse reaction rate of patients in the group was 6.00%, which was lower than that in the control group, and the differences in the data were statistically significant (P

Maillard reaction products (MRPs) could offer flavor and aroma for food, and also render functional characteristics. In this work, three squid skin Maillard reaction products with glucose (GSS), fructose (FSS) and lactose (LSS) were prepared, whose volatile compounds were analyzed by gas chromatography-mass spectrometer. And the antibacterial activities of three Maillard reaction products against Escherichia coli, methicillin-resistant Staphylococcus aureus and Vibrio harveyi were investigated. The results showed that the volatile compounds of squid skin MRPs mainly contained alcohol, acid, phenol, ester, aldehyde, alkane, alkene, amide and ester, among which alcohol was the predominant component in the GSS and LSS, accounting for 53.87±6.02 % and 83.67±3.64%, respectively, however, acid was predominant component in the FSS, accounting for 54.19±3.38 %. Surprisingly, 2, 6-di-tert-butyl-4-methylphenol (BHT), as a synthetic antioxidant, was firstly identified in these three MRPs, which directly indicated squid skin MRPs have antioxidant activities. It is demonstrated that the antibacterial abilities of LSS and GSS were superior to that of FSS, and Escherichia coli was the most sensitive to the three MRPs among the three tested bacteria. This study demonstrates squid skin MRPs possess antioxidant and antibacterial abilities, which shows promising and far-ranging prospect in the fields of food additives.

Lodging is a serious problem in plant growth, especially in crops growth of the natural habitat. In order to determine the influence of lodging on the growth characters of sweet sorghum, plants grown in natural saline-alkali environment were used to investigate the fresh weight, dry weight, sugar content in the stalks and the photosynthesis index of salt tolerant crop sweet sorghum. Results showed that lodging significantly reduced the growth of sweet sorghum, the fresh weight and dry weight was only 28.3% and 22.5% of the normal plants when lodging occurred after 49 days. Lodging also reduced the stalks sugar content of sweet sorghum, the stalk sugar content of lodged plants was only 45.4% of that in the normal plants, when lodging occurred for 49 days. Lodging reduced the growth and sugar content by reducing the photosynthesis parameters of sweet sorghum grown in the saline-alkali field, thus, affected the accumulation of photosynthate. Interestingly, with the extension of the lodging time, lodging led to a decrease in photosynthetic rate of sweet sorghum mainly due to non-stomatal factors.

It is very effective to solve the multi variable optimization problem by using hierarchical genetic algorithm. This thesis analyzes both advantages and disadvantages of hierarchical genetic algorithm and puts forward an improved simulated annealing genetic algorithm. The new algorithm is applied to solve the multiple traveling salesman problem, which can improve the performance of the solution. First, it improves the design of chromosomes hierarchical structure in terms of redundant hierarchical algorithm, and it suggests a suffix design of chromosomes; Second, concerning to some premature problems of genetic algorithm, it proposes a self-identify crossover operator and mutation; Third, when it comes to the problem of weak ability of local search of genetic algorithm, it stretches the fitness by mixing genetic algorithm with simulated annealing algorithm. Forth, it emulates the problems of N traveling salesmen and M cities so as to verify its feasibility. The simulation and calculation shows that this improved algorithm can be quickly converged to a best global solution, which means the algorithm is encouraging in practical uses.

As an abstract concept, ‘location error’ in is considered to be an important element with great difficult to understand and apply. The paper designs and develops an instrument to measure the location error. The location error is affected by different position methods and reference selection. So we choose position element by rotating the disk. The tiny movement transfers by grating ruler and programming by PLC can show the error on text display, which also helps students understand the position principle and related concepts of location error. After comparing measurement results with theoretical calculations and analyzing the measurement accuracy, the paper draws a conclusion that the teaching aid owns reliability and a promotion of high value.
