想象一下，你的面前有一个大圆柱，希望大家可以想象到，其法向量总是水平的。
If you imagine that you have this big cylindrical type in front of you, hopefully you can see that a normal vector is going to always be horizontal.
我们是知道如何去求水平集的法向量的，也就是垂直于水平集的法向量。
And we know how to find a normal vector to the level set, namely the gradient vector is always perpendicular to the level set.
但是在寻找法向量时，可以确定法向量与水平面垂直。
But, when it comes to looking for the normal vector, be rest assured that the normal vector to a horizontal plane is just vertical.
实际上，向量场，还是垂直于水平线，就像之前看到的那样，我只是想提醒一下大家。
Actually, they have a vector field is still pointing perpendicular to the level curves that we have seen, just to remind you.
也就是说f的梯度向量,应该与g的水平集垂直。
That means that the gradient of f is perpendicular to the level set of g.
为了进一步验证灌区运行状况运行水平的综合等级，采用“支持向量机”方法进行动态评价。
In order to further verify that irrigated the level of operational status to run a comprehensive level, a "support vector machine" method of dynamic evaluation.
