There is a material which we call invar . it is made of different metals . invar never expands or contracts much , and so it is useful in clocks 有一種我們稱之為不脹鋼的材料,它是由不同的金屬制成的,膨脹和收縮均很少。因此用在鐘里是很有用的。

A very low linear expansion coefficient sample carrier made from invar , ensures that temperature change has no effect on the sample position 由不脹鋼制成非常低膨脹系數的樣品載臺保證溫度變化對樣品的位置沒有影響。
