| 中文摘要: |
| 针对火工品长寿命、高可靠的特点，在长期贮存的条件下，评估其贮存可靠性是非常困难的。以步进应力加速贮存寿命试验方法评估了火工品的贮存可靠性，然后再把步进应力加速贮存寿命试验下的数据折算为恒定应力下的失效数据。根据其贮存寿命服从对数正态分布的规律进行统计分析，进而推算正常应力下火工品的贮存寿命。 |

| It is very difficult to assess the storage reliability of initiating explosive device under long term storage condition considering its characteristics of long life and high reliability. A step stress accelerated storage life test method to assess the storage reliability of initiating explosive device was put forward, and then converted the data under the step stress accelerated storage life test to the data under the constant stress accelerated storage life test. The storage life of initiating explosive device under the normal stress was analyzed and calculated based on lognormal distribution. |
