摘　　要：本文通过对月球探测资料和研究结果的系统分析 ,认为月球体积小、质量轻、离太阳较近 (温度高 )等因素是月球只有极为稀薄大气层的原因 ;论证了月球极地阴影区存在水冰的证据 ,并计算出水资源量约为 6 6亿吨。研究了月壤中氦 - 3的含量与月壤颗粒大小、矿物组成、元素成分和结构特征的关系 ,并估算了氦 - 3的资源量 ;探讨了月球表面的反射率 ;综合分析了月球区域性磁场的形成机制。Based on the exploration data and previous studies, the authors suggest that small volume and mass of the moon, the short distance from the sun ( i e . high surface temperature) result in the very tenuous and thin lunar atmosphere, demonstrate that there exits ice water on shadow area of the lunar polar region and calculate out 6.6 Ga tons of ice. By comparing the composition of rare gas elements in the lunar regolith and in the solar wind, the authors analyze the physical, chemical and isotopic effects of the solar radiation on the lunar surface materials, the distributions and contents of the 3He in the lunar regolith, point out that the content of 3He relates with grain size, the mineral components, structures and elemental compositions of the lunar soil, and evaluate the exploration values of 3He. The lunar surface materials govern the lunar reflectance. Based on the spectrum characteristics of the mare basalts, highland plagioclases and their mineral components which both of them are the main rocks of the lunar surface materials, the authors analyze the different reflectance of the lunar near side and far side. Not only is the lunar magnetic field the important part of the lunar environment but also great significance for studying on the lunar interior structures. The moon has regional scale distribution magnetic field which may result from great impact processes.$$$$
