摘　　要：针对采用直接相关法的传统相关测漏仪对硬件要求高、价格较贵的缺点,将极性相关的过零算法应用于相关测漏,并设计了硬件结构,进行了实验仿真,在实验室条件下,测量误差约为1%～3%,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 high demand for hardware and high price, the pipe-leak detector based on the polarity correlation algorithm with the cross-zero method is presented, the hardware design and the＇test is finished, the result only with the error from 1% to 3 % is gained, and its feasibility is testifies.
