摘　　要：采用Monte Carlo方法研究了GJB376规定的用计数数据估计火工品可靠度的方法和已建立的计量-计数评估方法在试验方面的等效性,根据评定准则采用这两种方法判定试验结果合格的接收率最大误差小于1%。对20种不同类型的火工品及两种人为设定为不合格产品,采用计量-计数法和步进法进行了对比试验研究,两种方法得到的可靠性评估结果一致。分析结果表明,计量-计数评估方法与GJB376规定的用计数数据估计火工品可靠度的方法等效,工程应用可行,对评估高可靠性的火工品,能大幅度降低样本量。By Monte Carlo, the equivalence between GJB376 method and variables-attributes assessment method was studied. According to reliability assessment rule,it is required that the maximum error of receptanee between two methods is less than 1%. Twenty kinds of qualified and unqualified products assumed artificially were assessed with variables-attributes method and run-down method respectively. The conclusions from two methods are consistent. Results show that variables-attributes assessment method is equivalent to GJB376 method and the variables-attributes method is feasible for assessing high reliability of initiating explosive devices with small samples.
