无限固体中水平流体层声传播函数的复变积分

Complex Integration of Sonic PropagationFunction in Horizontal Fluid Layer of Infinite Solid

水平流体层中放置点声源 ,层内任一点的振动情况可用声势函数 φ1来描述 ,φ1的形式较复杂 .根据复变函数理论 ,采用围道积分的方法 ,给出 φ1在复平面内进行简化处理的结果其形式简单 ,便于计算 .

The vibration of everywhere in horizontal fluid layer with sonic source of point can be described by sonic potential function φ1,which has complex form.Given a reduced result that is treated with theory of function of a complex variable.
