稀有气体在陨石研究中总是起着重要的作用。作为一种介绍,让我举两个例子来证明这一点。 1898年Ramcay在其论文中报道他企图在铁陨石中找到氦元素。因为那时氦元素已被人们所发现,并且被认为是我们太阳系的主要组份。然而他在一些铁陨石中并未找到氦,于是宣布,这些特殊的陨石不是来自太阳而是来自其它星球。今天我们认为,这一结论至少是很不成熟的。 第二个例子是一个近期的例子。有些种类的陨石长期以来被认为含有大量的稀有气体。在过去的几年 Rare gases always play an important role in meteorite research. As an introduction, let me give two examples to prove this. In 1898 Ramcay reported in his paper that he was trying to find helium in iron meteorites. Because then the helium element has been found by people, and is considered to be the main component of our solar system. However, he did not find helium in some of the iron meteorites and announced that these special meteorites came not from the sun but from other planets. Today, we think this conclusion is at least immature. The second example is a recent example. Some types of meteorites have long been thought to contain large amounts of rare gases. in the past few years
