首先尝试采用任意曲面椭圆方程，数值生成任意回转面上的叶栅c网格。

First attempts to apply elliptic equation of curved surfaces to generating C-type cascade grids.

我将要用椭圆选框工具创建一个曲面反射，不过如果你愿意你可以用矩形选框工具创建一个平面反射。

I will be creating a curved one with the? Elliptical Marquee Tool, but you may create a flat one with the? Rectangular Marquee Tool if you wish.

本文通过引入帽子屈服曲面，并对帽子曲面和塑性势能曲面用椭圆函数和圆函数形式进行了简化，从而得到了新的判定条件。

This article introduce the "cap yield curve model", simplify the cap yield surface and plastic potential energy surface by ellipse and circle, and get a new justify condition.
