这通常不是一个单位法向量。

And that is, in general, not a unit normal vector.

现在用单位法向量乘以那个。

Now, let's multiply that by the unit normal vector.

如果想用单位法向量来计算通量，还得先把它标准化到单位长度？

Now, if you wanted the unit normal vector to compute flux, then you would just scale this guy down to unit length, OK?

具体方法是，先给曲面定向，也就是选择两个单位法向量中的一个。

And the way it will work is that you have to choose an orientation of a surface, which just means choosing one of the two possible unit normal vectors.

这是约定的得到单位法向量的方法，这种做法使得，当沿着曲线行进时，法向量始终指向右手方向。

That is our convention to get a unit normal vector that points to the right of the curve as we move along the curve.
