The major work is as follows : solution of two dimensional radiation or diffraction fluid field . this thesis extends multipole expansion method to adapt to disturbed fluid fields of 2d floating bodies with asymmetric forms , which is applied with symmetric forms originally . and given the solution of potential velocity and hydrodynamic pressure of radiation and diffraction fluid fields , which is incited by a 2d arbitrary form , actual application field of the multipole expansion method has been enlarged
关于二维扰动流场的求解：将通常仅适宜求解具有对称形状二维物体扰动流场的多极展开法(保角变换方法)扩展至非对称形状二维物体，给出了任意形状二维物体的辐射和绕射流场的速度势及水动压力的频域解，进一步扩大了多极展开法的实际应用范围。
