They form a three-parametric, orthogonal net and may be chosen as coordinate lines of a special, curvilinear coordinate system.
它们形成三参数正交网，可以把它们选作特殊曲线坐标系的坐标线。

The difference equations for ADI method with the orthogonalcurvilinearcoordinate are developed, which are applicable to a complex boundary.
导出了本文正交曲线坐标系下的ADI法差分公式。本文方法边界适应能力强，计算时间短，内存少。
