对＂高成本、破坏性＂的成败型产品成功率的抽样检验, 如导弹命中率, 引信可靠度等的验收检验, 如何减少试验成本是科技工作者与工程人员共同关心的重要问题. 对关于平均试验次数最优的截尾序贯检验, 研究发现其平均试验次数具有随样本量截尾值增大而减少的趋势. 本文从工程实际应用角度出发, 将试验成本分解为试验准备费用与试验测试费用, 针对试验准备费用与试验测试费用的不同比值, 提出了一种关于最佳样本量截尾值的经济的截尾序贯检验方案, 从而能更好地节省抽样检验的试验成本. 最后, 以IEC1123 中的截尾序贯试验方案为例, 对本文所提方案的优良性进行了验证.

For the ＂high-cost, destructive＂ sample test of a proportion, such as the acceptance test of missiles hit ratio, the fuze reliability and so on, how to reduce the cost is the focus of management and researching. In the optimal truncated sequential tests on the average number of sample, we found that the average number of sample has decreasing trend with the increasing of truncated sample size. Through the decomposition of the test cost into test preparation cost and experimental test cost based on practical application, for the different ratios of test preparation costs and experimental test costs, the optimal truncated sample size and an economical truncated sequential test programme have been presented in this paper. Finally, the test plans in the International Electrotechnical Commission （IEC） standard IEC1123 have been used to validate the programme in this article.
