【摘要】：月球是地球唯一的天然卫星,早期学者认为地月系统是普遍存在的行星-卫星系统的一员,但是月球又有许多特征,如质量异常大,挥发分和Fe元素亏损等,传统理论难以解释这些特征。因此,针对月球的起源提出了四种学说:捕获理论,共增生理论,分裂理论和大碰撞假说。目前对大碰撞假说研究较多,但研究者们始终无法较好解释地月系统氧同位素的高度一致等特征。本文试探性提出新的月球起源分裂模型,能较好的解释某些月球特征,引起研究者们对月球起源新的思考。
[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.
