By using the transfer matrix method of multibody system, the hard problem of computation of the vibration characteristics of LRMLRS coupled with rigid bodies and elastic bodies is solved which is very difficult to the ordinary dynamic methods, and the vibration characteristics of LRMLRS which is varied when the number of rockets in the launch device is varied, is obtained conveniently. By developing augmented eigenvectors of the LRMLRS and its orthogonality conditions, the nonorthogonality problem of the multibody system including rigid bodies and elastic bodies is solved and the exact analysis of the dynamics response of the LRMLRS including rigid bodies and elastic bodies is realized. By using the random integer programming method, the hard optimization problem which contains continuous variables, discrete variables and random variables at the same time is solved. This method provides a technology for optimum design with random variables and discrete variables. The dynamic optimum design is realized to decrease the number of rockets consumption in the LRMLRS test.

The results indicated that CHCl3 was optimum reagent and the reaction temperature was better controlled at 10~15℃. Dinitrogen tetraoxide and nitric acidhad a detrimental effect on the yield and purity of 1,2-propanediol dinitrate. When the concentrations of dinitrogen tetroxide and nitric acid were below 1.00% and 5.53% respectively, these detrimental effects could be neglected. Under the optimum conditions, the yields and the purity of 1,2-propanediol dinitrate were 99.01% and 95.89%, respectively.

This paper is based on "Trilemma" which is induced from MF model. In order to overcome MF models inherent defects, this paper constructs a static model headed by government on choice of optimum exchange rate regime. Through the analysis of the model we can see that the choice of exchange rate regime is a dynamic process should be decided in real situation. No single exchange rate regime is right for all countries or at all time. Under certain condition intermediate regime may be the optimum one, but the possibility will decrease with the increase of international capital flow.
本文从蒙代尔——弗莱明模型精炼出的"三元悖论"出发,为了克服其内在的缺陷,构建了一个政府主导的静态最优汇率制度选择模型,模型分析表明:汇率制度选择是一个动态的相机决策过程,没有哪一种汇率制度对所有国家或某一国的所有时期都适合;在一定条件下,中间汇率制度可能是最优汇率制度,但是其可选择的区间随着资本流动程度的加大而缩小,最终最优汇率制度将内生的向两极分化。
