发射药加速寿命试验的相关性研究

用Ｓｐｅａｒｍａｎ的秩相关检验法和相关系数法定量地分析了某种发射药温度单应力加速寿命试验与现场贮存试验之间的相关性。结果表明，两者显著相关。给出了相关方程及两者之间的加速系数。

Accelerated Life Test Correlativity Research of Gun Propellant

Spearman's rank correlation test method and correlation coefficient method are used in this paper to analyse quantitatively the correlativity between the propellant's temperature single stress accelerated life test and storage one. The result indicates that they have wonderful nonlinear correlativity. Finally their correlation equation and the acelerated factors between them are presented.
