您要查找的是不是：
- first break of converted wave 转换波初至
- It is difficult to locate CCP exactly due to the asymmetry of converted wave ray path and the de pendency of CCP on depth, offset, P-wave velocity, and S-wave velocity. 但由于转换波射线路径具有明显的不对称性，且转换点坐标是深度、炮检距、纵横波速度及倾角等多种因素的函数，使得CCP的定位十分困难。
- Roddick dropped only two points in five service games in the second set, getting the first break of the match for a 4-3 edge. 这场比赛的第二盘，罗迪克在自己的五个发球局中只丢了两分，在4-3时拿到了这场比赛的第一个破发机会。
- The static correction method of converted P-SV waves is always a problem in converted wave processing. 摘要P-SV转换波静校正一直是转换波处理中的一个难题。
- And the scheme for P-SV waves was put forward as an example of converted waves. 然后，以P-SV波为例，给出了转换波快速射线的追踪方法。
- The processing expounded by the paper used the self made modules,including CCP gathers sorting,velocity analysis and NMO of converted wave (C wave) and static corrections of converted wave. 本文所述的处理使用了自行编制的模块 ,包括抽CCP道集、转换波速度分析及动校正和转换波静校正。
