早在1985年,美国华裔物理学家朱棣文就成功地用激光冷冻了原子,从而荣获1997年的诺贝尔物理学奖。激光为什么能制冷呢?原来,物体的原子总是在不停地做无规则运动,这实际上就是表示物体温度高低的热运动,即原子运动越激烈,物体温度越高;反之;温度就越 As early as 1985, the Chinese Chinese physicist Zhu Yuwen successfully used lasers to freeze atoms and won the 1997 Nobel Prize in physics. Why does the laser refrigerate? The original, the object’s atoms are constantly doing random movements, which is actually the thermal movement of the object temperature, that is, the more intense the atomic movements, the higher the object temperature; vice versa; the more temperature
