摘　　要：由于传统相关测漏仪采用直接相关法,对硬件要求高,价格较贵,提出将过零极性相关算法应用于相关测漏,并设计出硬件结构,进行了实验仿真,验证了其可行性。In order to remedy the faults of the traditional pipe-leak detector based on the straight-correlation analysis method, which has a high demand for hardware and a high price. Presented a new pipe-leak detector based on the polarity correlation algorithm with the cross-zero method,finished the hardware design and experimental emulation,and testified its feasibility.

关 键 词：管道测漏 极性相关 过零算法
