研究了球面波被有界障碍物散射的问题。证明了一般散射定理。这些是由放置在任意两个不同位置的点源的波散射引起的远场模式。散射体可以具有任何通常的特性，可穿透或不可穿透。光学定理作为一个推论被恢复。建立了点源与平面波散射场的混合散射关系。
The problem of scattering of spherical waves by a bounded obstacle is considered. General scattering theorems are proved. These relate the far-field patterns due to scattering of waves from a point source put in any two different locations. The scatterer can have any of the usual properties, penetrable or impenetrable. The optical theorem is recovered as a corollary. Mixed scattering relations are also established, relating the scattered fields due to a point source and a plane wave.
