	<span style=\"font-size:14px;\">本文将序贯概率比检验法应用到管道音波泄漏监测系统中，针对微弱泄漏信号特征，首先采用Kalman滤波法对监测数据进行动态滤波预处理；其次，在音波定位法的基础上运用序贯概率比检验法，判断边界阈值，提高了泄漏判断的准确性。实验结果表明了该方法的有效性和适用性。<br />
In
this paper, sequential probability ratio test is applied to acoustic pipeline
leakage monitoring system. According to the characteristics of the small
leakage, firstly, Kalman filter is used to preprocess the deformation
monitoring data; secondly, sequential probability ratio test method is used on
the basis of acoustic positioning method to improve the accuracy of leakage
judgment through judging boundaries. The experimental results show the validity
and applicability of this method.</span>
