| 摘 要： | 在不同口径的再生式液体发射药火炮中，普遍存在着频带分布很宽的大振幅高频压力振荡，这些压力振荡对目前使用的压电式压力传感器具有潜在的破坏作用，本文介绍了液体药再生喷射燃烧压力测量过程中所观测到的传感器损坏的几种方式，并且探讨了改善高频压力振荡条件下情感器耐用性的方法。

| Abstract: | For the different calibre regenerative liquid propellant guns, there exist generally high frequency pressure oscillations with the wide frequency range and large amplitude. Pressure oscillation may lead to repid fatigue failure or overload of piezo-electric type pressure transducer. In this paper, some ways of the transducer failure observed in the regenerative liquid propellantinjectioh and combustion process are presented, and how to improve the operating durability is discussed. |
