| 摘 要： | 针对数值计瓦尔兹─克力斯托夫保角变换过程中出现的数值奇异性，根据复平面上槽形内域边界的特点，分别导出了左右对称槽形内域和左右非对称槽形内域的保角变换公式，并给出保角变换过程和确定数值保角变换公式参数的迭代方法。最后，对二个具有典型特点的复杂边界进行数值保角变换计算，求得各自的变换参数和流势线网格。

| Abstract: | In this paper,numerical Schwarz-Christoffel tranSformations in left - right Symmetric and asymmetric channel region are derived on basis of characters of channel region boundary, in order to avoid numerical irregularity of numerical Schwarz - Christoffel conformal mapping.Numedcal iteration procedure and formulas tO determine all parameters of Schwarz-Christoffel tranSformation are given out. In the end, twO typical channel region boundaries are computed, each Parameter Of Schwarz - Christoffel transformation and stream-potential-line grid is shown. |
