当只有三阶色散时，除了产生较大时延差外，还会在两个偏振脉冲的前后沿产生较大的色散波。

When the third order dispersion effect exists, the more time delay difference is produced and the dispersion waves are produced at both the front and back edge of the pulse.

利用有一定间距的两部声纳基阵提供的目标方位和时延差的信息，实现对目标的被动测距。建立了测距物理模型，给出了后置距离滤波算法。

In this paper, we introduce passive ranging of target based on the bearings and time-delay information of dual arrays and filtering algorithm of ranging.

针对此问题，采用了输差法进行泄漏的检测与报警、瞬态负压波法与稳态相关时延分析法相结合进行泄漏点的实时定位技术。

It is based on the measuring the difference between the input and autput of the pipeline and by using the combination of the WSV and the SRDA to locate the leakage.
