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。
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。
