摘要
文中推导了直角坐标系和圆柱坐标系中的频域二阶单向波方程，对它们进行适当的离散化处理，分别得出了直角坐标系和圆柱坐标系中的二维二阶吸收边界条件．计算表明，这些吸收边界条件具有二阶精度，文中给出了一个计算实例，结果是令人满意的．
The second order one way wave equation in frequency domain is derived in Cartesian system and Cylindrical system respectively. After proper discretization procedure, the second order absorbing boundary condition in both systems is obtained. It is shown that they have the second order precision. Finally, an actual example is calculated with satisfactory results.
