polarity correlation meaning in Chinese

极性相关

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
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。
