中文摘要：

当包围液体媒介有吸收时，有弹性的球形的壳和圆柱的壳散布的回声被学习。用准确有弹性的理论和变量的分离导出的正常模式解决方案仍然是适用的。然而，散布形式功能不得不为吸收媒介被修改，否则无理的 resul twould 被获得。在吸收媒介的 backscattering 表格功能被重新定义，并且有充满的真空或稳固的物质的有弹性的球形、圆柱的壳的表格功能处于各种各样的吸收条件是计算的。结果证明包围液体的吸收导致巧合回声的著名变细在中间频率，但是它在散布的低频率的回声上在 fluence 有一些在壳内由 filler 导致了。

英文摘要：

Resonance scattering of elastic spherical shell and cylindrical shell while the surrounding fluid medium has absorption is studied. The normal mode solution derived using exact elastic theory and the separation of variables is still applicable. However, the scattering form function has to be modified for the absorbing medium, otherwise the unreasonable result would be obtained. The backscattering form function in the absorbing medium is redefined, and the form function of elastic spherical and cylindrical shell with vacuum or solid matter filled is calculated in various absorption conditions. The results show that the absorption of surrounding fluid leads to notable attenuation of the coincidence resonances in the mid-frequency, but it has a little influence on the low-frequency resonance scattering induced by the filler inside the shell.
