【摘要】:月球是地球唯一的天然衛(wèi)星,早期學者認為地月系統(tǒng)是普遍存在的行星-衛(wèi)星系統(tǒng)的一員,但是月球又有許多特征,如質量異常大,揮發(fā)分和Fe元素虧損等,傳統(tǒng)理論難以解釋這些特征。因此,針對月球的起源提出了四種學說:捕獲理論,共增生理論,分裂理論和大碰撞假說。目前對大碰撞假說研究較多,但研究者們始終無法較好解釋地月系統(tǒng)氧同位素的高度一致等特征。本文試探性提出新的月球起源分裂模型,能較好的解釋某些月球特征,引起研究者們對月球起源新的思考。
[Abstract]:The moon is the only natural satellite of the earth. The earth-moon system is considered by early scholars to be a member of the universal planet-satellite system. However, the moon has many characteristics, such as abnormal mass, volatile matter and Fe element depletion, etc. Traditional theories are difficult to explain these characteristics. Therefore, four theories are proposed for the origin of the moon: capture theory, co-proliferation theory, splitting theory and large collision hypothesis. At present, there are many researches on the large collision hypothesis, but the researchers can not explain the characteristics of the high consistency of oxygen isotopes in Earth-Moon system. In this paper, a new model of lunar origin splitting is proposed, which can explain some characteristics of the moon and cause researchers to think about the origin of the moon.
