So the torque is persuading the spin angular momentum to change.
所以力是使得旋转的角动量,改变的理由。
That means if there's torque, there's a change of angular momentum.
这意味着，如果那有一个力矩，就会有角动量的改变。
So the torque will also change direction and so this angular momentum, spin angular momentum will keep chasing the torque and start to rotate freely.
所以力也会改变方向,这个角动量，角动量会保持追着力,并开始自由地转动。
The angular momentum change must be torque t times delta t.
角动量的改变就是,力乘以δ
Note that in light with orbital angular momentum, the direction of polarization (denoted by the direction of the arrow) does not change across the cross section.
值得注意的是，具有轨道角动量的光，偏振方向(用箭头方向表示)在截面内部发生变化。
In this case, Angular throws an error, since an Angular application can only have one change detection pass during which all change detection must complete.
在这种情况下，角抛出一个错误，因为一个角度应用程序只能有一个变化检测通期间，所有的变化检测必须完成。
