What is more, deletion fitting method is not influenced by slight error of NMO correction velocity. This method can bring a fitted high-resolution P-wave section even though hyperbolae are not flattened thoroughly ( it is not sensitive to this.)

剔除拟合法的另一个优越性还在于它不受动校正速度的微小误差的影响，即使双曲线没有拉平，剔除拟合法对此也不敏感，照样能拟合出分辨率较高的P波剖面来。
