The reason there are three quantum Numbers is we're describing an orbital in three dimensions, so it makes sense that we would need to describe in terms of three different quantum Numbers.

我们需要，3个量子数的原因，是因为我们描述的是一个，三维的轨道，所以我们需要，3个不同的量子数，来描述它。

Remember, we need those three quantum Numbers to completely describe the orbital.

要知道，我们需要三个量子数，才能完全描述一个轨道。

So if, in fact, we want to describe a wave function, we know that we need to describe it in terms of all three quantum numbers, and also as a function of our three positional factors, which are r, the radius, phi plus the two angles, theta and phi.

实际上，我们想描述波函数，我们知道我们需要,用这三个量子数来描述它，同样，波函数还是,三个位置变量的函数，它们是r半径，还有两个角度theta和。

Given that we now know, at least for policy reasons we know well enough, two of our three numbers we need to concentrate on that third.
