他们靠什麼移动，像啥东西从一树枝到一树枝干啥。

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.

This Paper describes the calculations about mathematical and physical pendulums, the principe of produced acceleration, the adjusting and measuring methods and the error analysis methods of acceleration.

本文介绍了有关单摆与复摆的计算方法、产生加速度的原理、冲击加速度的调整与测量方法及其误差分析。

I lowered off the top of the boot flake what seemed like 80-90 plus feet and then started my slow pendulums back and forth under the boot flake.

我从boot flake顶部下降，大概有八九十英呎，然后开始慢慢在boot flake下来回摆荡，经过一番苦战，我最后到达凹壁，我往上爬一短的10a段落，然后在此确保。

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。

When there is plenty of rope available, the following method illustrated in Figure 20-3 is most secure. The best river man goes first belayed by the second best who goes last. When A gets across, he moves upstream and sets up a belay opposite B. and the next wader ties in at B. Then C pendulums across taking about the same path as A.

水性最好的A首先过溪，由水性次佳，同时也是最后一个过溪的B负责确保工作，当A到达对岸之后，走到B的正对岸做好确保，下一个渡溪者C在B点套入胸部绳圈确保，C的渡溪路径与A相同，当C渡溪时B要给出绳子而A要将绳子收紧，如果C失足被冲掉，会被冲到对岸

When there is plenty of rope available, the following method illustrated in Figure 20-3 is most secure. The best river man goes first belayed by the second best who goes last. When A gets across, he moves upstream and sets upa belay opposite B. and the next wader ties in at B. Then C pendulums across taking about the same path as A. while B lets rope out, and A keeps the rope taut. If C falls, he should be pendulumed to the most favorable bank (hopefully to A so that the crossing is accomplished).

水性最好的A首先过溪，由水性次佳，同时也是最后一个过溪的B负责确保工作，当A到达对岸之后，走到B的正对岸做好确保，下一个渡溪者C在B点套入胸部绳圈确保，C的渡溪路径与A相同，当C渡溪时B要给出绳子而A要将绳子收紧，如果C失足被冲掉，会被冲到对岸（最好是冲到A抵达岸边的点）。

The second is to cut a mere 100 calories from your diet , which is the equivalent of a tablespoon of butter.
