折射界面复盖层平均速度(?)选择得是否正确,对于折射波洼地震勘探工作结果灼解释精确度有着重大意义。本文介绍一种简而易行的确定(?)值的方法——平均速度量板法。文中做出了理论量板,说明了使用
The correct choice of the average velocity (?) Of the refrac- tive interfacial cover is of great importance to the interpretation of the results of refrac- tive seismic exploration work. This article presents a simple and easy way to determine (?) Values - the average speed plate method. The article made a theoretical volume board, indicating the use of
