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。

In fact for readers of Paradise Lost, and this has been an experience now for a few hundred years, it does often seem as if there were some mysterious life force, a pulsating through Milton's dense and driving lines of unrhymed, iambic pentameter.
