Q scan, a qualitative analysis method, is analogous to velocity scanning or frequency scanning.
前者类似于速度扫描或频率扫描,属于一种定性分析方法;
2
How the formation dip, velocityscan parameters and coherence determination affect velocity analysis accuracy is specially discussed on the basis of summing up traditional velocity analysis methods.
基于传统的速度分析方法,着重讨论了地层倾角、速度扫描参数及相干性测量给速度分析精度带来的影响。
3
The technics parameters, such as the laser power, scanvelocity, powder feed rate and the Z axis increment, which influence quality and shape were analyzed in this article.
