摘要
基于对数值网格生成的椭圆型偏微分控制方程中混合偏导数项非线性系数特性的 研究，从理论上推导了用于控制网格正交性的一种新源项给定形式，并讨论了其具体的数值实 现方法，数值计算结果表明，该新源项形式对生成网格的正交性具有很强的调节和控制能力。
Based on the characteristics of the non-linear factor p in grid generation equation, a new procedure of control function which is used to control grid orthogonality is deduced theoretically and mathematically The numerical processes of present method in applications are discussed in detail. Numerical results show that the new procedure has strong influence on the grid orthogonality control.
