When the invar is paired with alloy 3Ni24Cr_3 to composea bimetal, the temperatare range of high sensitivity is also enlarged.

当它与3Ni24Cr_3配对作成双金属片时，最大灵敏度的温度范围也得到扩大。

Geodetic levelling should be done with staves in which the divisions are marked on a strip of invar.

大地水准测量必须使用分划刻在因瓦带上的水准标尺。

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.
