With this approach, a mathematical model of ASVG is developed. The method is simple and can be used to analyze the detailed internal properties of an ASVG. It overcomes the disadvantages of the two methods generally used, one is a method for modeling an ASVG by getting differential equations according to the topology of the ASVG circuit, which is very complicated and it is difficult to get a unified model expression of an ASVG; the other is a method for modeling an ASVG by considering the whole ASVG as a voltage source, which is too simple to analyze the detailed internal properties of ASVG.

该方法既克服了根据ASVG装置拓扑结构列写微分方程组的建模方法过于复杂且不易获得统一模型表达式的缺点，同时又克服了将ASVG装置等效为电压源的建模方法太简单而无法用于分析ASVG装置内部性质的缺点，具有建模简单又能分析ASVG装置的内部性质的优点。

Thirdly, fuzzy control method and PID method were used respectively to design temperature self-adjustment controller of carbon fiber concrete laminate beam,by the MATLAB simulation it is found that the PID method has higher speed but is more sensitive to the fluctuation of system parameter ,it is suit to the regulating when the heat transfer coefficient fluctuates diminutively and the structure has little heat transfer with the environment;fuzzy control can be adapt to the parameter variety in a large scale , it is suit to the regulating when the heat transfer coefficient fluctuates greatly.

In this paper, the modeling theory of multi-rigid-body dynamics was thoroughly investigated in order to make up the shortcoming in the above modeling method. The major research achievements are as follows:①Based on the matrix of direction cosine between the body-fixed base and the reference base, and Poisson equation of a rigid body rotating, the coordinate transformation method for the modeling of treelike multi-rigid-body dynamics is derived. The method is very routinization and easy to use the computer to carry on the symbol derivation.

It change the normal method for "beginning control" and "goal control". With the development of living level, upholster is dispensability for indoor, the using of decorative material produce plenty of poisonous、baleful chemical substance. These substance make the air indoor into bad, and threaten the healthy in the door if these cumulate .What"s more it will reduce work efficiency. The past method of IAQA is subjective assessment or giving priority subjective assessment. But people will adapt to indoor environment due to settle in the door long-term, which it lead to incorrectness. So, we can"t only use subjective assessment for IAQ. In this article, the author bring forward the best and the reasonable assessing method ,which it is combining the subjective assessment to objective assessment.

随着生活水平的提高，室内装潢成为家居装饰不可缺少的部分，装饰材料的应用，会产生大量的有毒、有害化学物质，使得室内的空气质量变差，且长期累积会威胁室内人员的身体健康，导致工作效率低下，过去对室内空气品质的研究仅用主观评价方法或以主观评价为主对室内人员的主观感受做调查，但是由于室内人员对室内的环境具有适应性，从而造成评价的不准确，且过去对化学微污染物的影响没有定性的研究，因此，用该方法进行评价显然是不准确的，所以，本文提出用主观评价和客观评价想结合的评价方法对室内空气品质进行综合评价。
