一 | (ECNS) -- China exported 1.043 million vehicles in July, up 81.3% year on year, marking the second consecutive month exports exceeded one million units, the China Association of Automobile Manufacturers said Wednesday. New energy vehicle exports reached 553,000, up 5.7% from June and 145.5% year on year. NEVs accounted for more than half of China’s vehicle exports for the second straight month. The association said China’s integrated automotive supply chain, along with rapidly evolving smart-driving and in-car interaction technologies, has helped support export growth and adapt vehicles to overseas market needs.

（来源：天津数港）原标题：嫦娥五号月壤矿物中，我国科学家发现了......加关注点击蓝字”天津数港”，关注我们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。

二 | △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。来源：“天津日报”微信公众号审校：张志华邓晶龙编辑：裴丽艳潘玥返回搜狐，查看更多责任编辑：
