摘要
研究全失重环境下带核液体和腔内多层液体的受迫振动问题．采用球函数和Ｇａｌｅｒｋｉｎ方法给出了问题的解析解．研究结果表明，对于理想不可压缩流体在线性理论范围内，刚体的激励运动不激发液体自由面或多层液体交界面的波动响应，从而使问题转化为液泡的运动．
Forced oscillation of both the liquid layer around a sphere and the two liquids in a spherical container is investigated in the present paper. Using spheric functions and Galerkin's method, analytical solutions of the problems are obtained. The results show that the oscillation of the liquid free surface or the interface of the liquids cannot be excited by the translational excitation of the rigid body, which means that the liquids move in drop or bubble style.
