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。
