钟摆的摆动

In the movement of the hands of the clock, my grandfather lived again.

随着钟摆的摆动，我的祖父在我心中又活了过来。

There is, for instance, a kind of steel called invar (from"invariable") which does not change its dimensions as temperature changes; it is valuable for making pendulums, since, if the length of a pendulum changes, its time of vibration changes.

不过也有一两个例外，例如有一种钢叫做殷钢(从"invariable"一词而来)，在温度变化时它的大小尺寸不变；这种钢对于制造钟摆很有价值，因为如果摆长改变，摆动的周期就改变。

There are one or two exceptions. There is, for instance, a kind of steel called invar (from"invariable") which does not change its dimensions as temperature changes; it is valuable for making pendulums , since, if the length of a pendulum changes, its time of vibration changes.

"We were looking at the slow steady swing of the pendulum as it counts the seconds," the younger one said,"and my friend has said it would be easy to stand in front of the clock for one hour, to stand without moving and say 'here it comes, there it goes' as the clock's pendulum swings back and forth."

"我们再看钟摆慢慢摆动计算时间，"年轻一些的人说道，"我朋友说在钟前站一小时很容易，要站着不动，还得在钟摆摆动时说：'摆过来，摆过去'。"

Very simple apparatus with swinging pendulums and levers have demonstrated that energy CAN be extracted from centrifugal force, when an unbalanced oscillation between centrifugal force and gravity is created.

非常简单的钟摆摆动仪器和手段已经证明，能源可以从离心力中得到，当离心力和重力之间的不平衡振动。

Then you go over the two bascule bridges passing the swinging pendulums push the stone ball aside and run down the wooden ramp with full speed (lower right-hand corner of the picture).

然后你就可以在这两个bascule桥梁传球的摆动钟摆推石头球搁在一边，跑到木斜坡以全速。

The Pendulum Drop Test quantitates spasticity in knee muscles by recording a ratio of two angles of knee angular displacement.

钟摆摆动试验通过记录膝关节屈伸的速度及对比角度变化来量化肌肉痉挛：病人坐位，小腿下垂于检查台边缘，被动完全伸直后以自由落体的方式自然下摆。

不过也有一两个例外，例如有一种钢叫做殷钢(从&invariable&一词而来)，在温度变化时它的大小尺寸不变；这种钢对于制造钟摆很有价值，因为如果摆长改变，摆动的周期就改变。

In 1656, Christiaan Huygens invented the pendulum clock, which used weights and a swinging pendulum.

在1656年，克里斯蒂安惠更斯发明了钟摆的时钟，用度量衡和单摆摆动。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
