| Abstract: | This paper has investigated the coupling vibration eigenvalue problem of gas and elasticbody.The compatibility condition of the eigenvalue perturbation equation derived from thecoupling problem,and the asymptotic expansion of simple eigenvalue have been obtained.Inaddition,to give reasons for the perturbation expansion,the holomorphic property of thissystem with respect to gas density parameter has been discussed. |
