So, that gives me a slice of my graph by a vertical plane, and the slice has a certain slope.

那样给出图像的一个垂直切面，这个切面上有某个斜率。

We'll be slicing things by a plane that is now in the direction of this vector,u and we'll be looking at the slope of the slice of the graph.

用沿着向量方向的平面,切开图像,然后看图像的剖面图，找出斜率。

OK, and for a given value of x, what we will do is we'll slice our graph by this plane parallel to the yz plane.

对于给定的x，我们要做的就是，用平行于yz平面的平面去切图像。

Over the ocean, where there is no radar to warn of impending collisions, safety rules require a plane to occupy a slice of sky 160 kilometers long and 300 meters thick, severely limiting traffic.
