这还是比较容易想到的，假如这是位置矢量，这是它的变化量。

Well, it might be good to think of, maybe, the position vector, and maybe its variation.

也许我应该用位置矢量来考虑,如果你们觉得有帮助的话。

Or, maybe I should insteadthink of it in terms of a position vector if it helps you.

矢量数据指的是通过几何结构定义的数据，如线段表示街道，而点表示位置。

Vector data refers to data defined by geometric constructs, such as line segments representing a street or points representing single locations.

That turns out to be a very nice way to produce vectors, given one vector, the position vector.

这或许是一个得到矢量的很不错的方法,给你一个位置矢量

The most important vector is the position vector that tells you where the object is.

最重要的矢量是位置矢量,用来表示物体的位置

I think it's clear, the position of the object with respect to the ground, this vector is the same as the position of the object with respect to the plane, plus the position of the plane with respect to the ground.

我觉得很明显,物体相对于地面的位置,这个矢量等于,物体相对于平面的位置矢量,加上物体相对于地面的位置矢量
