- 摘要：The Environmental Impact Assessment Law of our country stipulated that the project and construction items should be assessed using the method of environmental impact. The planning office becomes the agent of environmental impact assessment is as important as the agent of project construction for the first time. The scope, duty, and the legal responsibility of the agent, which does the assessment using the method of environmental impact, should be standardized and perfected. It will be helpful to implement the work of environmental assessment and make it legal.303|8|0更新时间：2023-11-28

- 摘要：In this paper, a simple genetic algorithm (GA) is presented for optimizing the structural systems with discrete design variable. First, the origin, basic process of GA was discussed. In order to improve the convergence of GA, considering the difficulty in choosing the probability of crossover and mutation, an adaptive GA, in which the probability of crossover and mutation were varied depending on the fitness values of the solutions, was introduced. Finally, the availability of the adaptive GA was shown by an example.722|793|0更新时间：2023-11-28

- 摘要：The prestressed tension is an important part of the prestressed concrete component construction.In order to find out the influence on the concrete hollow slab of different tension sequence,in this paper,the 30 m assembled post tensioning concrete hollow slab is simulated by the means of finite element analysis software ANSYS. The variation of the hollow slab's stress and strain are discussed according to the result of the different tensioning sequence, then, the reasonable sequence of tensioning prestressed steel wires is put forward.725|7|0更新时间：2023-11-28
- 摘要：Considering the difficulties of mathematical analysis and the complex computer programming of numerical methods in solving dynamical problems of the multi-body dynamic system for the hoisting mechanism of a crane, in this paper, a multi-mass-multi-freedom model is set up and the simulation system of the model is built up applying MATLAB/SIMULINK toolbox. The differential equations of the model is solved with adaptive-step fourth-order Runge-Kutta method. In the study, the typical work conditions of the hoisting mechanism, such as start rise from ground, start rise/down in air, brake conditions, were simulated. The dynamic performance of the hoisting mechanism is studied and the results obtained are valuable to practice. This study improves the modeling accuracy of the hoisting mechanism and the results of precious theoretical analysis and numerical computation conclusions. The movement of every discrete body of the system can be modeled applying the methods suggested by this study and more consistent results between model and actual hoisting mechanism can be achieved.853|8|0更新时间：2023-11-28

- 摘要：This paper puts forward a theoretical analysis model for air temperature characteristic inside a car during parking and starting. The analysis solution shows that the variation of air temperature inside a car with time follows index number law and becomes stable when the time is long enough. The theoretical analysis not only reveals the law of air temperature variation in clear physical meaning, but also coincides well with the experimental results.565|11|0更新时间：2023-11-28

- 摘要：This paper analyzes the urban vulnerable groups in house needs, as well as housing security policy; the conclusion is to carry out low-rent house system. Furthermore, the shortcoming lies in system, fund, object, quantity and information nowadays is pointed out. The countermeasures perfecting the low rent house system are presented. There is a strategy named "helps to others and oneself" to realize a policy that the powerful and the vulnerable groups must have symbiotic development, to form steady normative source of insurance fund, to play an effective role in low rent house stock, to establish managerial mechanism which all the departments are on duty, to build system from low rent house application to its supervision, to take the manner of rent allowance, to perfect correlative policy of low rent house and house security.501|606|0更新时间：2023-11-28
- 摘要：The marketization, internalization and electronization of financial industry in China are inevitable. Adapted to this situation, the financial supervision has to be strengthened. The modern financial supervision system is the base and guarantee to strengthen the financial supervision; it has the character of unity of supervision organization, perfect instrument of supervision, harmonization of supervision legality and internalization of supervision thought etc. Establishing the modern financial supervision of China should consummate the financial supervision legal institutions in China. Although the laws were constituted, such as and some related regulations, yet cannot conform to the WTO rules and the market economy development and be not enough to structure the legal institution base of the modern financial supervision in China. As a result, it has to be revised further, improved and to work out financial laws and regulations in order to form a modern financial supervision system in our country.629|596|0更新时间：2023-11-28
