As they do so, each pair applies pressure to a soft ring around the driveshaft. The pulsating muscles collectively and continuously pinch the shaft and apply a rotational force, causing it to turn.
每一组收缩都会对环绕在传动轴上的项圈产生压力，于是，这些搏动的肌肉会一齐连续地挤压传动轴，形成转动力，从而产生旋转。
The DC electromotive force output by AC generator can have quite big pulsating voltage.
交流发电机输出的直流电动势会有较大的脉动电压。
