关于炮长微光指挥镜(二代)气密性和水密性问题的探讨

Study on Air tightness and Water tightness of Low level light Commanding Instrument of Chief Artillermen

通过对炮长微光指挥镜Ｃ２组试验中质量问题的解剖，分析了气密性检查方法的缺陷，特殊结构的光学产品气密性检查和水密性检查不能等效代替。

By the dissecting of the guality in testing low level light commanding instrument C 2 group of chief artillermen, the defects in existing tightness testing method is analyzed, pointing out that the air tightness testing and the water tightness testing of optical products with special structure are not equivalent and can not be sub stituted. The measures for up grading the tightness are also proposed.
