This paper analysed the pattern and composition of residual metal in diamond fracture surface by ways of Scanning Electron Microscope (SEM) and Energy Dispersion Spectrum (EDS).
Semblance spectrum is the important tool to judge whether the migration velocity is correct or not and obtain the velocity update amount in residual curvature migration velocity analysis.
相干谱在剩余曲率偏移速度分析中，是判别速度是否正确以及求取速度更新量的重要工具。
