ray travel-time

基本解釋

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.
該方法通過聚焦深度分析和CRP射線追蹤來獲得剩余時(shí)差，避免了疊前反射層析成像繁重的旅行時(shí)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.
像這樣的偽時(shí)間和旅行每天都在發(fā)生并被我們?nèi)祟惖奶綔y工具（僅舉幾個(gè)例子，如哈勃空間望遠(yuǎn)鏡、設(shè)置在夏威夷的一部龐大的凱克望遠(yuǎn)鏡和錢德拉X射線觀測衛(wèi)星）拍攝下來。
It is based on the least square of the difference between the real reflection first break time and corresponding modeled ray-tracing travel time.
此法以反射地震資料中的觀測初至旅行時(shí)與模型射線追蹤旅行時(shí)之差的最小平方法為基礎(chǔ)。
