Mathematical Processing of a Singualr-integral in Acoustic Computation

Xu Zhongchang Wu Dongdong(College of Science,Naval Univ.of Engineering,Wuhan 430033)  
This paper introduces a new method of mathematical processing of a singular integral which appears in acoustic scatterings by submerged objects of arbitrary shape and arbitrary acoustical impedance,and a progressional formulae dealing with the aboved singular integral is presented.
