| 摘 要： | 本文就作者提出的高精度开路边条件进一步讨论了如何给出它们在各类曲线坐标系下形式的一般方法，并给出了在平面极坐标系下，相应的一阶和二阶ＡＯＢＣ的具体形式。通过数值例子，同一些已有的相应ＯＢＣ作了比较，从而证明了本方法的有效性。

| Abstract: | A general method designing open boundary conditions in different curvilinear coordinates for transient waves ispresented in this paper. It bases on the high precision AOBC offered by the author. The expressions of the AOBC of the first and second orders in polar coordinates are derived as the examples. The numerical test appears that the method is reasonable and effective. |
