多元判别分析在库存发射药质量监测中的应用

Application of Multivariate Discriminatory Analysis to the Examination of Storage Propellant Quality

多元判别分析在事物的分类判别中应用很广泛,该文提出了一种以密闭爆发器试验数据为基础,应用多元判别法判定国储发射药的质量等级的方法。对8批不同储存期11/7火药的质量判定结果与实际完全一致。这种方法可用于库存发射药的质量跟踪监测、考察其弹道性能随贮存期的变化规律、判定发射药质量等级的变化。

Multivariate discriminatory analysis has been usedwidespreadly to classify objects. The paper suggests a method to judgethe quality grades of storage propellants by multivariate discriminatorybased on their data measured in closed bomb tests. The method, whenused for judging the quality of eight lots 11/7 propellants with differ-ent store time, gives a result in full accord with actual one. It may beapplied to the tracking examination of storage propellants quality peri-odically, and the study of the changes of ballistic performances andquality grades of propellants with store time.
