The experimental results show the validness of the mechanism analyses.2. According to the generation mechanism of the leak acoustic signal, the characteristics of the leak acoustic signal are investigated. The auto correlation technology is adopted to descript the leak signal characteristics due to the ability to analyze the coherence of time series. A new procedure to identify the leak acoustic signal from the disturbed noises is proposed based on the conjunction of correlation and approximate entropy algorithm.3. The principle and application in leak location of the correlation and the adaptive filter techniques are introduced. The problems of the traditional leak location methods are analyzed.4. In order to establish the leak detection signal model, the leak acoustic propagation characteristics are investigated experimentally.

从泄漏声产生机理出发，分析了管道泄漏处湍流拟序结构与空泡间相互作用的机理，认为在该机理作用下，泄漏声信号产生过程具有&不可重复&的特征；由于相关函数具有分析时间序列拟序结构的能力，且近似熵从统计的角度区别时间过程的复杂性，因此，提出将信号相关分析和近似熵理论相结合的方法，提取泄漏声信号&不可重复&的特征，辨识管道泄漏故障发生；在实际检测现场，由于各种管内和管外固定声源噪声(如阀门噪声、工地施工噪声等)常导致泄漏误判和漏点定位错误，重点分析了管内固定噪声源的产生机理和特征，为复杂干扰环境下的泄漏辨识提供理论支持。
