【环球网科技综合报道】9月14日消息,近日,中国科学家对月壤的研究更进一步——月球上不仅有水,而且存在高含量水。
KHIAM, Lebanon -- A Reuters videographer killed in Israeli shelling of southern Lebanon was laid to rest in his hometown Saturday in a funeral procession attended by hundreds of people.Draped in a Lebanese flag, Issam Abdallah’s body was carried on a stretcher through the streets of the southern town of Khiam, from his family’s home to the local cemetery.Dozens of journalists and Lebanese lawmakers attended the funeral.Abdallah was killed Friday evening near the village of Alma al-Shaab in south Lebanon when an Israeli shell landed on a gathering of international journalists covering exchange of fire along the border between Israeli troops and members of Lebanon’s militant Hezbollah group. The Lebanese army said in a statement Saturday that Israeli troops fired a shell the day before hitting a civilian car used by journalists killing Abdallah and wounding others. The army said that other areas in south Lebanon at the time were targeted by an Israeli helicopter gunship and artillery, including the outskirts of the villages of Marwaheen, Kfar Chouba, Aita al-Shaab and Odaisseh.Lebanon’s Foreign Ministry asked Beirut’s mission to the United Nations to file a complaint against Israel over Friday’s shelling, calling it a “flagrant violation and a crime against freedom of opinion and press.” The statement was carried by the state-run National News Agency.Israeli military spokesperson Lt. Col. Richard Hecht told The Associated Press in Jerusalem on Saturday, “We are aware of the incident with the Reuters journalist and we are looking into it.”Hecht did not confirm that the journalists had been hit by Israeli shells, but called the incident “tragic,” adding, “we’re very sorry for his death.”Reuters said in a statement that two of its journalists, Thaer Al-Sudani and Maher Nazeh, were wounded in the same shelling, while Qatar’s Al-Jazeera TV said its cameraman Elie Brakhya and reporter Carmen Joukhadar, were wounded as well.France’s international news agency, Agence France-Presse, said two of its journalists were also wounded. They were identified as photographer Christina Assi, and video journalist Dylan Collins.AFP reported Saturday that Assi was in need of blood transfusions at the American University Medical Center in Beirut where she was hospitalized. The Lebanon-Israel border has been witnessing sporadic acts of violence since Saturday's surprise attack by the militant Palestinian group Hamas on southern Israel.Journalists from various countries have been flocking to Lebanon to monitor the situation.。中国科学院官微发文称,地球化学研究所科研团队对嫦娥五号月壤样品开展研究,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。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。据悉,这一成果日前在国际学术期刊《自然·通讯》发表。根据科研团队的估算,太阳风质子注入为嫦娥五号月壤贡献的水含量至少为170ppm,相当于每吨月壤中至少含有170克的水。而今年1月份首次在月壤中发现有水时,测算的数据为每吨月壤中约有120克的水。这样一看,对比就很明显了,也就是为什么将嫦娥五号月壤"水"判定为高含量水。

二 | 证实了月球有水,那么这些水又是从何而来的呢? 据介绍,我国科研团队在今年1月份首次在月壤中发现有水时,发布了一组数据。根据研究显示,1吨月壤中约有120克水,1吨岩石中约有180克水。并且结合样品分析,月壤中的水绝大部分是来自于太阳风的贡献,岩石中多出来的水则可能代表了月球内部水。

三 | 据报道,在今年6月份,我国科研团队还发现嫦娥五号着陆区月壤中明显含有羟基形式的“水”,但平均含量较低。同时研究表明,嫦娥五号月壤样品中肯定存在来源于月球内部的原生水。研究团队对嫦娥五号月球样品的实验室分析,发现了至少一种含水矿物:羟基磷灰石,证明了嫦娥五号月壤样品中存在来自岩浆结晶过程的“水”,说明“水”在月球晚期岩浆活动过程中不仅存在,而且可能起到了非常重要的作用。
