ray travel-time

常见例句

The method gained residual moveout by focus depth analysis and CRP ray-tracing, which avoided tedious pick-up of travel-time in prestack reflection tomography.
该方法通过聚焦深度分析和CRP射线追踪来获得剩余时差，避免了叠前反射层析成像繁重的旅行时拾取工作。
Pseudo-time travel like this happens every day, with pictures taken by the Hubble Space Telescope, the mammoth Keck telescopes in Hawaii and the Chandra X-ray Observatory satellite to name just a few.
像这样的伪时间和旅行每天都在发生并被我们人类的探测工具（仅举几个例子，如哈勃空间望远镜、设置在夏威夷的一部庞大的凯克望远镜和钱德拉X射线观测卫星）拍摄下来。
It is based on the least square of the difference between the real reflection first break time and corresponding modeled ray-tracing travel time.
此法以反射地震资料中的观测初至旅行时与模型射线追踪旅行时之差的最小平方法为基础。
