摘　　要：本文利用将有水振型按无水振型展开的办法,给出了弹性悬臂梁与流体自由耦合振动时的解析解。其中流体的密度随深度按指数变化,流体的范围可从有穷变到无穷。文中并根据不同的组合情况做了具体计算。Based on the method of expressing the coupling vibration modality into the series of vibration modalities in air, the analytic result of coupling vibration of cantilever beam with fluid is obtained. The deisity of the fluid varies with the depth of the fluid. The area of the fluid varies from limit to unlimit. The calculating results have been got under the different combinations of the conditions
