| 摘 要： | 本文主要是利用流体媒质界面处速度和能流的连续性边界条件,定量地分析,研究弹性纵波在界面处的半波损失问题。通过分析、研究,得出了弹性纵波有无半波损失的正确判据,及“入射波由波阻小的媒质射入波阻大的媒质,界面处反射波存在半波损失”不是普遍成立的结论。

| Abstract: | This paper analyses and studies quautitatively the Half- wave loss
problem of elastic longitudinal wave by using continuous boundary conditon of speed and energy flux on a plane interface of fluid mediums.It obtains the exact criteria of determining whether elastic longitudinal wave has Half-wave loss or not. |

| Keywords: | fluid medium half-wave loss energy flux wave resistance boundary condition |
