摘　　要：空间推进系统可靠性评估时,采用Lindstrom-Maddens(L-M)法评估比传统方法得到的结果更高。对比分析评估数据后发现L-M法更合理,因此建议采用L-M法进行可靠性评估,可以在满足可靠性指标前提下防止对产品提出过分苛刻的要求,从而降低设计难度和减少试验费用。When assessing the reliability of space propulsion system,the result obtained by Lindstrom-Maddens（L-M） method is much higher than by traditional method.By comparing and analyzing the data of assessment,it is revealed that L-M method is more reasonable.Therefore,the author suggests adopting L-M method in reliability assessment.Under the precondition of satisfying the reliability index,it can prevent an excessive strict demand on product,reduce the design difficulties and decrease the test cost.
