为研究某推进系统气路启动特性，找到造成影响减压阀建压稳定性的原因，获得稳定的减压阀出口压力建压过程，依据系统仿真方法及相关试验，对该推进系统气路启动特性进行了研究。结果表明，减压阀阀后压力稳定性与阀后的管径及阀内的N_M~L存在关系。

In order to find the reason which affects the pressure-establishment stability of the re- lief valve and obtain the stable pressure-establishment process at outlet of the relief valve, the starting characteristics of a pneumatic system used in some propulsion system were researched by means of system simulation method and relevant tests. The result shows that the pressure stability behind the re- lief valve depends on the diameter of the pipe behind this valve and damping area inside this valve.
