摘　　要：利用实验室油气管道平台和声发射仪,建立了模拟城市输送管道泄漏检测系统。通过实验对气、液管道小泄漏信号特征与衰减特性进行了分析,在改变管道压力、泄漏量以及传感器间距等参数状态下,分别分析了管道泄漏信号的幅值随管道压力、泄漏量、传感器间距变化的规律,对城市输送管道泄漏检测进行了有益的探索。By suing oil-gas pipeline platform and acoustic emission instrument, the simulating urban pipeline leakage detecting system was built in laboratory. Based on experiment, the features of small signal induced from the leakage in gas-liquid piping and the attenuation of signals were analyzed. In the case of changing the pressure in piping, leakage and sensor spacing, the rules of amplitude change for leakage signal were analyzed, which is useful in the detection of leakage occurred in urban pipeline
