作为与计算机、半导体、原子能并称的二十世纪四大发明之一,激光3d组三组六中奖多少钱技术已经在许多行业中得到广泛应用。不过,提到激光,大多数人能想到的往往是其在机械加工上的应用。

其实,除了在工业切割、焊接、以及医疗美容3d组三组六中奖多少钱上的应用外。激光还有许多其它用途,比如在制冷上的应用。激光冷却这一概念最早于1962年由苏联学者提出,沉寂了一段时间后才被学界关注。1985年,著名的美国华裔科学家朱棣文使用激光冷冻原子,成功实现了低温环境,并因这一发明而获得1997年的物理学奖。

激光是能量高度集中的光束,由于它发出的光粒子具有统一的方向,所以这些粒子非常集中。当激光束3d组三组六中奖多少钱射入物体内时,由于进入的粒子数很多,使得物体内的微粒变得非常拥挤,它们便不能像原来一样“活蹦乱跳”了,从而降低了分子的热运动,这种激光制冷技术被称为多普勒冷却技术。
