A negative face has an outward normal pointing in a direction opposite that of the positive x-axis.

负向的外法线指向与正x轴相反的方向。

Well, we know we are on the X-axis.

我们在x轴上。

So, let's do the first one on the x-axis.

首先算x轴上的。

The highest probability now is going to be along the x-axis, so that means we're going to have a positive wave function every place where x is positive.

概率最高的地方是沿着ｘ轴，这意味着只要在ｘ,大于零的地方波函数都是正的。

Another way to represent a point in a plane is I've got a radius and I've got an angle from the x-axis, right, and that's a standard thing you might do.

平面上面的点的方法,也就是极坐标,上面那种方法其实是，如果你们喜欢我这么说的话,笛卡尔坐标表示法。

On the x-axis is the rate of unemployment, on the y the rate of inflation.

The key, I concluded, is to plot the different kinds of consequences of work (y-axis) against the different types of groups (x-axis) that do the work.
