天然河道二维正交贴体坐标系的生成

Generation of Two-dimensional Contact Orthogonal Coordinate System for Naturai River

在河渠两相邻边界布点,逐次求解拉普拉斯方程组,可生成二维正交贴体坐标系。本文介绍了生成该坐标系及计算有关坐标转换参数的通用程序,给出了贴体坐标系生成实例。

By setting points along the two adjacent boundary lines of nat鹯ai river aud by solution of Laplace equations step by step, a two-dimensional contact orthogonal coordinate system will be generated . This paper presents the general p(?) (?)the coordinate systen and computationof converse para-meters for the related coordinates . A practical example is given in this paper about the generation of contact coordinate system.
