| 摘要: |
| 目前药柱贮存寿命失效临界点一般都是假设确定的。采用药柱空穴率非接触诊断技术和热加速老化累积损伤法，实测得ＣＭＤＢ固体推进剂的贮存寿命失效临界点，预测了其使用寿命。 |

| Abstract: |
| The critical service life for rocket grain was presumed at present.In this paper,with the aid of discontiguous diagnostic technology and method of accumulated damage using accelerated aging or heat air-oven the critical service life was determined and the service life for CMDB solid pram Pedant was predicted’The results in this paper are of practical significance for service life prediction of solid rocket grain. |
