为了获得这样的曲面，我们要用到基本曲面的再分。

To obtain such a plane, we use the base surface's decomposition.

通过对某汽车车身腰线处的过渡曲面光顺，给出了复杂过渡曲面的光顺方法，并阐述了基本曲面理论交线的重要作用。

The smoothing methods for complex transitional curved surfaces are given by smoothing waist surfaces for an auto-body, then the theoretical curves are emphasized in transitional surfaces smoothing.

基本上，这两个公式把沿曲线的功，和被曲线包围的曲面上的旋度，联系起来了，曲面是以该曲线为边界的。

Both of these formulas basically relate work on a curve with what happens to the curl on the surface that is enclosed by this curve, that is bounded by this curve.
