解决了平面声波与充填可压缩流体的刚性圆柱体轴线上的液体球相互作用的问题。相互作用的量度是辐射力：球面上液体压力积分的时间平均值。为了确定速度场势，解决了波通过球面和圆柱体内表面的绕射问题。以刚性球形粒子为例，讨论了辐射力与入射波频率的关系。
The problem of the interaction of a plane acoustic wave with a liquid sphere located on the axis of a rigid cylinder filled with a compressible fluid is solved. A measure of interaction is the radiation force: the time average of the integral of the liquid pressure over the sphere surface. To determine the potential of the velocity field, the problem of the diffraction of a wave by the sphere and the inside surface of the cylinder is solved. The case of a rigid spherical particle is considered as an example, for which the radiation force and the frequency of the incident wave are correlated
