中文摘要：
研究了海洋波导中可穿透目标时谐声波散射传播远场分布的性质，构造了透射问题解的集合，使得所构造解的集合在边界上的限制在某个Hilbert空间中是稠密的，确定了传播远场分布的集合在某个Hilbert空间中是完备的．这些性质对研究海洋波导中的逆透射问题有重要的应用．
英文摘要：
The properties of propagation far-field patterns corresponding to the scattering of time harmonic acoustic waves by a hounded penetrable obstacle in an ocean waveguide were concemed with. The sets of solutions to the transmission problem were constructed such that the restriction of these solutions to the boundary of the penetrable obstacle is dense in a Hilbert space. Then conditions under which a set of propagation far-field patterns is complete in a Hilbert space were determined. These properties are important in investigating inverse transmission problems in an ocean waveguide.
