给出了齐次规划问题KKT点的一个等价性质，采用对约束函数k次方的方法得到齐次规划问题的一个局部鞍点。

When the object and constraint functions are continous, it shows the relations of KKT points and local saddle-points.

这个过程并没有改变物体的基本性质：变形后仍等价于原始形态。

This does not change the object's essential properties: the transformed shape is equivalent to the starting shape.

根本上说，以下性质是等价的，一个向量场是梯度场，等价于积分与路径无关，也等价于向量场是保守的。

And, basically, we say that these properties are equivalent being a gradient field or being path independent or being conservative.
