摘要
采用覆盖域的概念，给出任意形状封闭薄壳的内部散射声场的统一表达式，并用互易原理可求解封闭薄壳在外力作用下的内部声场。本文所提出的这一方法适用面广，可以求出任意形状封闭薄壳（等厚度或不等厚度）的内部声场。实验验证证明了本文提出方法的可行性。
By using a concept of covering-domain, a common expression about interior scattering sound field of arbitrary-shaped closed thin shell is given in this paper, and the expression of interior sound field of the closed thin shell due to the action of external force can be derived out by using the reciprocity theory. The method in this paper, which can be used to calculate the interior sound field of arbitrary-shaped closed thin shell (equal or unequal thickness), suits a large scope. It is verified to be correct by corresponding test.
