the return stroke

The spring absorbs the energy of the impact, the shock absorber releases it on the return stroke, and prevents an oscillating force from building up.

弹簧吸收碰撞产生的能量，减震器在回程行程将能量释放，并阻止振荡力产生。

The conveyer can not only work in a long distance and ultra width, but also ensure the return stroke of the belt is stable, and meet the use requirements of large conveying capacity.

该输送机不仅能长距离超宽运行，还能保证皮带回程平稳，满足输送量大的使用要求。

The bright return stroke travels upward at around half the speed of light, and is too fast to capture in more than one image.

闪亮的回击以光速的一半速度上行传播，由于它的速度太快，在一张图象中不能捕捉到这一过程。
