Texture coordinates are named (s, t) in order to distinguish them from the (x, y) used for vertex positions (in literature, (u, v) is commonly used instead).

将纹理坐标命名为(s, t)是为了与用于表示顶点位置的(x, y)区分开来(从文字角度来讲，(u, v)更为常用)。

If x and y were functions of t instead of being functions of u and v then it would be the same thing.

如果x，y是t的函数，而不是u，v的函数,那么还是一样的。

x, y and z, in terms of t, are given here.

这是x、y、z与t的关系。

Remember, we don't do a one-to-one correlation, because p x and p y are some linear combination of the m plus 1 and m minus 1 orbital.

记住，我们不需要把它们一一对应，因为ｐｘ和ｐｙ轨道是,ｍ等于正负１轨道的线性组合。
