摘　　要：提出了基于多序贯概率比检验法,并以检测各种泄漏所需时间的期望为目标函数来优化备选假设,同时对判决函数进行改进以达到迅速有效地检测出各类泄漏的目的。仿真实验证明经改进的多序贯概率比检验在管道泄漏检测中是简单实用和可行的。In order to perform rapidly and effectively for different size leak detection, a method is presented based on multi-sequential probability ratio rest（M-SPRT）, which alternative hypothesis is optimized through the objective function for detection time expectation, and the decision function is improved simultaneously. The simulation results demonstrate that M-SPRT method is simple, feasible and effective in pipeline leak detection.
