travel-time tomography

基本解释

In order to solve this problem, the introducing of gradient of event in travel-time tomography is a current developing direction.
为了克服这个困难，在走时层析成像中引进同相轴梯度是当前的一种发展方向。
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。
So we research the reflection tomography from travel-time and its gradient data.
因此，我们研究了利用走时及其梯度进行联合层析成像的方法。
