The potential force field act mainly on model when contour curve close target region edges.
同时当轮廓曲线到目标区域附近时发挥梯度场较精确的优点。
So, it's a force field is the gradient of a potential so, I'll still keep my plus signs.
有一个力场,它是某种势的梯度,我们还是保持正号。
There is another thing that we know because if a force derives from a potential 0 then that means its curl is zero Thats the criterion we have seen for a vector field to derive from a potential.
我们还知道,如果力是由势产生的,那么其旋度是,这就是我们得到的,关于从势产生的向量场的准则。
