摘　　要：采用不同方法推导两种典型三维结构的声辐射模态及其辐射效率。求解方法采用单元辐射器法和基函数法,并对两种方法进行比较,阐明各自的优越性和局限性,以及相应的应用场合。对球形结构和圆柱形结构进行数值计算,并对各自特点进行分析。The acoustic radiation modes and radiation efficiencies of two classical three-dimensional structures were deduced by different methods. These methods included element radiators method and basis function method. The advantages and disadvantages of the two methods were clarified, and their application occasions were demonstrated by comparison of each other. Simulation and characteristic analysis of spherical and cylindrical structures were carried out.
