为了探测地下结构的速度分布,我们采用了快速射线追踪方法——散射法与搜索法对二维速度反演结果不断校正.计算结果表明,这种校正是十分有效的.

In order to make clear the subsurface velocity distribution, the inverted 2-D velocity was corrected repeatedly by the technique of fast ray- tracing, the technique of scattering and the technique of searching. Results show that all the measures adopted are very effective and successful.
