Extensive research has shown that fractional atomic masses always mean mixture of isotopes.
进一步的研究揭示出：部分原子质量常是同位素的混合物。
The way to do that (and much else that is needed in order to read the history written in meteorites) is to look at the exact mixture of atomic isotopes in them.
去实现上面设想的方法(和很多其他为了能阅读写在陨石上的历史而需要的方法)是观察它们之中原子同位素的确切混合比例。
