摘　　要：针对序贯概率比检验(SPRT)无法控制抽取样本量等不足之处,提出了一种改进的抽样检验方法——序贯网图检验．该方法的要点是在原SPRT问题中插入一系列检验点,将单个检验问题拆分为若干对假设检验的问题．计算表明,新方法比SPRT有明显的改进;与国际公认的抽样标准IEC1123所建议的截尾序贯概率比检验方法比较,其改进是全方位的．This paper proposed a new sampling plan, the sequential mesh test, in order to overcome the disadvantages of the widely used Sequential Probability Ratio Test （SPRT）. The main idea of the new plan is to divide a SPRT test problem into a series of subproblems by inserting a number of test points. The paper presented in detail how to realize the new plan, and showed that the new plan has a much better control of the sample number than SPRT does. Finally it showed that the new method is also more powerful than IEC 1123 the well-known international standard for sampling inspection.
