The method not only disposes the disturbance yawp , but also shortens the response time of leaks detection, and heightens the precision of leaks location.

两种方法的结合不但可以有效地去除干扰噪声，而且缩短了泄漏检测的响应时间，提高了泄漏定位的精度。

With the problem of noise disturbance in leak detection and location of pipeline, a signal process method based on empirical mode decomposition (EMD) and cross-correlation was presented.

针对长输管道泄漏检测与定位中噪声干扰问题，提出了一种基于EMD分解和相关分析的管道泄漏检测与定位方法。
