速度势函数 meaning in Chinese

velocity potential function

In this method , the interpolation polynomial is related to several cells nearby , so the body surface is smooth , the potential function and its derivative is uninterrupted on the whole surface . moreover , because the interpolation based on b - spline is very accurate , it can enhance the efficiency of calculation and make a good numerical result by coarse gridding
在这种基于b样条的面元法中，由于插值多项式涉及附近的几个单元，而不像一般的面元法只限制在一个单元内，因此物体表面是光滑的，速度势函数及其导数由于采用样条函数表达，在整个物体表面也是连续的。
