二 |     (ECNS) -- A dike along the Jialu River in Zhoukou, Henan Province, breached Thursday night after heavy rainfall and upstream flood discharge, flooding the Fifth People’s Hospital and a local driving school, authorities said.    Rescuers evacuated 432 people, including 357 patients and medical staff and 75 from the school. All hospital patients and personnel were relocated to three other medical institutions.    The breach, approximately 30 meters wide, occurred Thursday night due to combined pressure from upstream flows on the Jialu River and backflow from the Shaying River.    Rescue operations continued Friday with 290 firefighters deployed.                             。△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。
