spin direction的意思|示意

In particular, with time evolution, distribution and swing of the mean spin direction is closely related to the structure of the space where the initial coherent state centred in.

特别是随着时间的演化，系统的平均自旋方向的分布和摆动也与初态所处的空间结构有着密切的联系。

Before you actually jump, twist your upper body the opposite direction of the desired spin direction.

起跳之前，先把上半身向相反方向扭转。

Imagine it like this: If you spin something, the direction of the axis tends to wobble.

这样想一下：如果你旋转什么东西，这个轴的方向将会变化。
