saddle point

基本解释

In three-dimensions it could even be a saddle point.
在三维空间的时候，这个甚至可以是鞍点。
And so, at this saddle point here, if we go north or south, then we go down on either side to the Valley.
在鞍点的地方，如果我们向北或者向南，我们都向下走到了山谷。
See the point in the middle, at the origin, is a saddle point. If you look at the tangent plane to this graph, you will see that it is actually horizontal at the origin.
我们来看中间的那个点，在原点上，那就是一个鞍点，在这点做一个切平面,你可以看到这个切平面,是在原点上水平的。

For if the bulls are indeed back in the saddle, they are going to need these indices to follow along as some point soon.
