| 摘 要： | 月球极度亏损挥发分，但是月壤中赋存有大量的稀有气体，主要来源于太阳风注入、宇宙射线作用和放射性同位素衰变等过程。月岩和月壤样品的稀有气体研究，不仅是获取月球表面形成和演化历史、近地空间小行星撞击历史等的重要内容，更是解译40亿年以来太阳风演化的惟一可行途径。本文主要介绍月岩和月壤中的太阳风记录、宇宙射线暴露年龄、Ar-Ar定年以及稀有气体测试技术等方面研究的进展。

| Abstract: | The moon is highly depleted in volatile elements. On the other hand, the lunar regolith contains large amounts of noble gas implanted by the solar wind, which serves as precious archives of the Sun's radiation history.Cosmogenic noble gas produced in lunar regolith by interactions with galactic cosnfic ray and radiogenic ~(40)Ar as a dating tool for lunar soils and rocks are also briefly introduced. |

| Keywords: | Moon cosmic-ray exposure age lunar regolith solar wind noble gas |
