你能够在单群理论或这多群理论里，单群理论假设，中子能量和所有的东西，要达到一个能量，我们必须要做出些调整。
And you can do it in one-group theory or multi-group theory. One-group theory assumes that the neutron energy and everything is going on at one energy and we have to make some adjustments.
研究人员利用所谓的离子显微镜来比较月球岩石中正常的氢元素含量及同位素氘的含量，元素氘比氢多带一个中子。
The researchers used what's called an ion microscope to compare the amount of normal hydrogen in the moon rocks to the amount of the hydrogen isotope deuterium, which carries an extra neutron.
科学家用到了一种叫离子显微镜的仪器，来比较月球岩石上氢的含量与重氢含量（重氢比普通氢多带有一个中子）。
The researchers used what’s called an ion microscope to compare the amount of normal hydrogen in the moon rocks to the amount of the hydrogen isotope deuterium, which carries an extra neutron.
