The compressed spring when force is removed, returns to its original position, the distance that a spring compressed under force depends on the rate of the spring.

当压紧力撤除时，被压紧的弹簧恢复到初始状态，在压力作用下，弹簧的压缩变形量取决于该弹簧的刚度。

The paper analyses the high precision design and adjustment of cylindrical spiral compressed spring under condition of installation dimension being ascertained basically.

这里分析了在安装尺寸基本确定条件下圆柱形螺旋压缩弹簧的高精度设计与调整。

It also tells you that if you compress the spring, compress it means x is now-- x is measured from this position, where the spring is neither compressed nor expanded.

它还能告诉你,如果压缩弹簧,压缩就意味着现在 x...,x 是从这个位置开始算的,在这个位置弹簧既没有压缩也没有伸长
