遥感探测发现月表普遍存在水（OH/H₂O），然而由于缺乏直接的样品分析证据，月表水的成因和分布一直存在争议。矿物水含量和氢同位素比值近日，中国科学院地球化学研究所科研团队针对嫦娥五号月壤样品开展了研究，通过红外光谱和纳米离子探针分析，发现嫦娥五号矿物表层中存在大量的太阳风成因水，估算出太阳风质子注入为嫦娥五号月壤贡献的水含量至少为170ppm。嫦娥五号矿物表层显微结构的TEM图结合透射电镜与能谱分析，揭示了太阳风成因水的形成和保存主要受矿物的暴露时间、晶体结构和成分等影响。该研究证实了月表矿物是水的重要“储库”，为月表中纬度地区水的分布提供了重要参考。这一成果日前在国际学术期刊《自然·通讯》发表。Chinese scientists have found high water content in lunar soil samples brought back by the country's Chang'e-5 lunar probe, according to a peer-reviewed study published in Nature Communications on Saturday.The study was conducted by a research team from the Institute of Geochemistry at the Chinese Academy of Sciences.Through the analyses by infrared spectroscopy and nanoscale secondary ion mass spectrometry, the team found a large amount of solar wind-derived water in the samples' mineral surface, and estimated a minimum of 170 parts per million (ppm) water content attributed to solar wind proton implantation in lunar soils. The results of spectral and microstructural analyses revealed the formation and storage of solar wind-derived water are mainly affected by exposure time, crystal structure and composition of minerals. This study showed that lunar surface minerals are important "reservoirs" of water, and provided an important reference for water distribution in the mid-latitude region of the lunar surface. Chinese scientists have discovered a new mineral – Changesite-(Y) – in Chang'e-5's lunar samples. The discovery was jointly released by the China National Space Administration and China Atomic Energy Authority on Friday.推荐阅读： 《天宫对话》丨天宫为媒 CGTN作桥 搭建中非航天交流新篇章我国科学家发布嫦五月壤最新研究成果
