In this paper, we firstly discuss all kinds of multiple elimination methods.

首先对多次波压制国内外研究现状做了简单的阐述。

The computational efficiency and accuracy of the present method have been compared with that of the Green's function method.

计算结果表明，采用该方法可以得到消声器传递损失的高次波效应。

Successive positions of the wave front are then given by the envelopes of the secondary waves.

因此波前的相继位置即为次波的包络面。

It is possible to realize the multiple arrival tracking with the multistage technique because the multiple arrivals are different combinations or conjugations of the simple incident, transmitted and reflected waves at the velocity boundaries.

基于多次波是通过速度界面简单的入射、透射、反射及转换波按一定规律及原理的不同组合，因此可实施分区多步计算技术。
