velocity discontinuity

While serve for beaching of bank, permeable spur dike could elaborate meantime merit sever of discontinuity revetment slacken littoral current velocity, brought accumulation of sediment, touch the object to preserve bank.

当用作护岸工程时，丁坝可以发挥其间断性护岸的优点，减缓近岸流速，促使泥沙淤积，达到保护堤岸的目的。

( 3) The velocity discontinuity surface generally exist at the depth of 25 km.

25km深度普遍存在速度间断面；

Using teleseismic PS converted waveform to get Receiver Function is one of efficient methods which can study velocity discontinuity of the crust and mantle structure under seismic station.

利用远震PS转换波波形提取出的接收函数来研究地震台站下方地壳、上地幔速度间断面结构是有效的方法之一[1]。

In this paper, the split-strip discrete method is used to analyse the 3-dimensional deformation and tension distribution of cold rolling strip, By considering the noncontact deformation area, the velocity discontinuity is avoided at the deformation field entrance.

本文采用分条离散法分析冷轧带材的三维变形，求解出前后张力分布。通过考虑入口非接触变形，使变形区入口处不产生速度间断。
