数值试验表明，如果背景网格的两个连续网格线之间的总弧长彼此显着不同，Smarareh-Abolhassani和Stewart的表面网格生成的参数空间投影方法会产生网格振荡。为了消除电网振荡，对参数变量的评估提出了三种修改：第一是Smarareh-Abolhassani和Stewart提出的UPS和APS方法的结合；第二种方法包括来自相邻线的信息；第三种是采用前两种方法的混合方法。数值试验表明，三种方法中，第一种方法是提高网格平滑度最简单、最有效的方法。 （作者）
Numerical tests show that Smarareh-Abolhassani and Stewart's parameter space projection method of surface grid generation produces grid oscillation if the total arc length between two successive grid lines of the background grids significantly differ from each other. In order to eliminate grid oscillation, three modifications of the evaluation of parameter variables are proposed: the first is a combination of the UPS and APS methods proposed by Smarareh-Abolhassani and Stewart; the second method includes information from adjacent lines; and the third is a hybrid method that employs components of the first two. Numerical tests show that of the three methods, the first method is the simplest and most effective method to improve grid smoothness. (Author)
