SIMS技术可以以离子束轰击月岩样本，从而使研究人员调整电荷水平，用磁石分离出离子。

The SIMS technique bombards the lunar samples with a primary ion beam that allows the researchers to separate the ions with a magnet, depending on the charge.

在最新的一项研究中，研究人员在月岩和月陨薄碎片中找到了磷灰石的矿物颗粒。

In the new study, researchers located grains of the mineral apatite in thin sections from the moon rocks and meteorite.

8月5日发表在《科学》杂志上的文章中，对月岩中氯元素的新分析结果表明，月球的含水量仅相当于地球内部的万分之一至十万分之一。

New analyses of chlorine in those rocks, published Aug. 5 in Science, indicate that the moon contains just one-ten-thousandth to one-hundred-thousandth the water that the Earth's interior does.
