在最初的歌剧院设计竞赛中，这些壳并没有几何学上的定义，但在设计过程的开始阶段，这些&壳&被定义为由一系列的混凝土肋骨支撑起来的抛物线。

Two types of coupling vibration problems are considered in thispaper,i.e.those of spherical shells coupling with fluid and ehstic mediumIn particular,for elastic medium,we adopt the basic assumptionsemployed in the Pasternak model of elastic foundation and include theeffect of the foundation's thickness,however,to re-derive the relationshipbetween the pressure and deformation by the principal of minimumpotential energy.

文中考虑了两类耦合振动问题，即球壳与流体和球壳与弹性介质的耦合振动。特别对于弹性介质，采用工程上常用的Pasternak假设但考虑了简化模型中弹性层厚度的影响，利用能量方法重新推导了该模型的压力——变形关系。
