随着原子能研究的发展,近年来低温科学的研究,也跟着产生,的确它的重要性并不在原子核物理学的研究之下。氦元素现除常被利用作为供给实验原子的中子的原料外(由放射体元素蜕变中获得),它的重要用途,便是供作低温测验用的冷却媒介,有了氦的酷冷温度圈,我们才能看到原子在绝对零度左右所产生的物理化学变化和其他物质构造的奇妙现象。 With the development of atomic energy research, the research of low-temperature science has also followed in recent years. Its importance is not under the study of nuclear physics. In addition to the usual use of helium as raw material for the supply of experimental neutrons (derived from the decay of radioactive elements), its important use is the cooling medium for cryogenic testing, with the cryogenic temperature of helium Circle, we can see the atom in the absolute zero around the physical and chemical changes and other material phenomena of the wonderful phenomenon.
