尽管激光分离同位素(LIS)才出现十几年,但由于其突出优点,受到世界各国的重视,发展极快。其中有大量课题与力学紧密相关,但迄未见到从这两个乍看起来关系不大的学术领域的结合上作出的总结和评述。本文希望填补这一空白。 1.激光同位素分离 从天然矿物或人工产物中将对人类用处较大的同位素分离出来,对于国民经济和军事应用十分重要。例如,天然矿物中铀235的含量只有约0.7％;而世界
Although laser isolated isotope (LIS) appears more than ten years, due to its outstanding advantages, it has been paid great attention and developed rapidly by all countries in the world. There are a large number of topics that are closely related to mechanics, but we have not yet seen the summaries and comments made on the combination of these two at first glance-less academic fields. This article hopes to fill this gap. 1. The separation of laser isotopes from natural minerals or artificial products will be used for larger human isotopes isolated for the national economy and military applications is very important. For example, the content of uranium 235 in natural minerals is only about 0.7%; and the world
