If we let go, the elastic energy, as the spring passes through the equilibrium point, is converted to kinetic energy . 如果我们释放弹簧，那么弹簧经过平衡点时，弹性能就转变为动能。
Hence, the loss of gravitational potential energy of the block equals the gain of elastic potential energy of the spring . 因此，该物块的重力势能的减少，等于该弹簧的弹性势能的增加。
If the force p is reduced or made zero, the elastic force will restore the spring to its original unstretched condition . 如果力P减小或变为零，那么弹性力就使弹簧恢复当初的未伸长状态。
I made several trips with brother mance, as he was called, to plantation shacks, sleeping on shuck mattresses . 我和曼斯大哥--别人是这样称呼他的--一起到种植园的棚屋去了好几次，睡的是弹簧床。
The specimen spring rate increases, thus making it necessary to increase the mass size enormously to provide valid test results . 试样的弹簧率也增加，因此必需大大地增加质量，以提供有效的试验结果。
Because of differences in the expansion rates of the two metals, the thermostatic spring winds up or unwinds with changing temperature . 由于两种金属的膨胀率不同，当温度变化时，恒温制弹簧将卷绕或松开。
The instrument includes a weight suspended in a spring connected to a registering needle which notes the vibration on a strip of celluloid . 这种仪器有一个重锤悬在与记录针联接的弹簧下面。记录针在一条电影胶片上记录振动。
The ring on the spring string rings during springtime 弹簧弦上的环在春天鸣响。
Rim - locks without latch - bolt for hinged doors on ships 船上折叠门无弹簧闩弹簧锁
Air spring for automotive suspension - rubber bellows 汽车悬架用空气弹簧橡胶气囊
