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。

It is also shown that under the same conditions, the values of the LWI gain with incoherent pumping are evidently larger than those without incoherent pumping exceptΦ=0 and the time reaching the steady state is shorter; varying the initial condition doesn't change the stationary value of the LWI gain but can remarkably affect the transient evolution process of the LWI gain.

研究还表明，与不存在非相干泵浦时相比，除了相对位相Φ=0的情况外当存在非相干泵浦时系统可得到大得多的稳态增益，而达到稳态所需的演化时间也短得多；初始条件的变化不改变稳态增益的大小但对瞬态演化过程有明显的影响。
