通过对不同初始条件下的CMT排水量进行了分析,发现CMT排水速度主要受CMT内的压力变化的影响:CMT无遮流板排水实验中所有排水量随时间的变化曲线都是单调递增的,且都有一个较为明显的拐点,在拐点后,斜率明显增大,说明排水速度增加显著;CMT加遮流板排水实验中排水量曲线的拐点不明显且出现时间较无遮流板排水实验要早,说明排水速度增加得较早;CMT加遮流板排水实验如果PRZ初始压力较大,通过改变CMT的初始温度,将会引起排水总量较大的变化;排水速度平衡时间受CMT压力平衡响应时间的影响,且较CMT压力平衡响应时间快。

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 paper obtains some conclusions after many theories analysis and empirical tests: Firstly, Volume-price relativity is extensive: total volume or it's change, disassembled volume promoting price movement or it's change all has plus relativity to equilibria price. Secondly, there is unilateralisms Granger casuality in bullmarket, while there is bidirectional Granger casuality in bearmarket. There is not nonlinear Granger casuality in both markets. Third, Behavior finance has remarkable effects after contrasting to different investment conditions. Moreover, causality research by moving tendency can reflect the stable relation while usual causality research can't do. Fourth, it can be ture forecasing key period of tendency reversion by building volume-price elasticity coefficient containing composite information of volume-price and analysis methods of moving tendency.
