- The travel time curve for a P-SV wave is nearly hyperbolic, and the velocity derived therefrom takes both P and SV raypaths into account. This is a"composite" velocity which will be used for NMO corrections the same way as those done for P-P wsves. P-SV波的时距曲线仍然是一条近似的双曲线,但它包含着纵波和横波的双重影响,由此得到的速度称为复合速度,可用于动校正和叠加。
