这都是根据题目要求而定的，有一个问题是，找出向量的分量就足够了吗？，还是说我们需要解出一条直线的方程？

It depends what the problem is asking the question is, is it enough to find the components of a vector or do we have to find the equation of a line?

假设我们的向量场有两个分量。

Let's say that our vector field has two components.

为了求出高度，需要知道这向量的垂直分量是多少。

And to find the height of this thing, I need to know what actually the normal component of this vector is.
