针对某单兵攻坚弹初速异常降低的问题,在原因分析的基础上,采取了针对性措施,并通过加速老化试验进行了相应的试验验证。验证结果表明,初速异常降低的问题的确是由发射药盒及装药搭配不合理造成的长贮失效引起的,采取的措施也是有效可行的,并对今后弹药长贮性能的考核提出了针对性建议.

In view of abnormal initial velocity decrease for some assault-fortification rocket, based on reason analysis targeted measures were adopted, and corresponding experimental verification was carried out through accelerated aging test. Verification results show that abnormal initial velocity decrease is caused by unreasonable collocation of launching-powder with its container, the measure we take is feasible and effective and some suggestions are put forward for future ammunition long-time storage assessment.
