摘　　要：本文研究了管道泄漏引发的瞬态负压波在管道中的传播过程，设计了一种能够有效地提取泄漏压力波形特征信息的分段积分非法，提出了基于此算法的瞬态负压波结构模式识别判定管道状态的方法。In this paper the propagation process of instantaneous negative pressure wavecaused by leak of crude Petroleum transported pipeline is studied. An effective phased integralalgorithm is designed to distinguish the particular feature of instantaneous negative pressurewave. According to this algorithm a pattern recognition method to differentiate the mede ofpiPeline is proposed.
