对贮存14～15年以上的各种引信射击及分析检查证实:引信经长期贮存后会不同程度地出现可靠性失效,其失效率与所用机构、元件、材料有关。长期贮存后失效率总的趋势如下:机构为纯机械者一般变化不大,若含药柱,则该部分失效率较高,而含药盘时,该部分失效率在低温环境条件下最高,甚至在高温条件下亦出现失效。对同一种或同一系列的引信,贮存在东北沿海、华东、华南地区可靠性下降迅速,而在干寒地区则往往未见明显差异。造成长期贮存后引信可靠性下降的因素主要有:锈蚀;火工品受潮后感度和输出能量下降;药盘的压药机械性能下降;火工品受油污后,敏感度和输出能量下降。
On the storage of 14 to 15 years of fuze shooting and analysis confirmed that: fuze after long-term storage will be varying degrees of reliability failure, the failure rate and the use of institutions, components, materials. The general trend of failure rate after long-term storage is as follows: institutions are purely mechanics generally little change, if the medicine column, then the failure rate of this part is higher, and with drug tray, the failure rate of this part is the highest in low temperature environment, Even in high temperature conditions also appear failure. For the same kind or same series of fuses, the reliability stored in the northeastern coast, east China, and southern China decreased rapidly, while in dry and cold regions, there was often no obvious difference. After long-term storage, the reliability of the fuze declines mainly due to the corrosion, the sensitivity and the output energy drop after the pyrotechnics damp, the mechanical properties of the drug drop of the medicine plate decrease, and the sensitivities and output energy of the pyrotechnics drop after the oil is contaminated.
