If The Clockwise Rotation

The idea that he had was, if you go from me to you, with a clockwise rotation, you go from you to me by a counterclockwise rotation.

他的想法是，如果你从我这里到你这里，顺时针旋转，你从你这里到我这里是逆时针旋转。

If you saw the figure spinning counter-clockwise first, then you were significantly more likely to be able to reverse the direction of rotation than if you saw it spinning clockwise first.

如果你第一眼看到的旋转舞女是逆时针自旋，那么与第一眼看到的是顺时针旋转的观察者相比，你能够看到旋转舞女进行相反方向旋转的可能性要大很多——这可能是因为我们观察一个物体旋转时的自然倾向就是顺时针，这在第一张图中也得到了证实。

Positive values for the angle rotate the object clockwise if you look along the positive rotation axis.

角度为正值，则表示若您顺着正旋转轴方向观察，对象是按顺时针旋转的。
