This conclusion, combined with the data obtained from the short-lived Hf-W and Sm-N d isotopic systematics, suggests that the Moon was initially accreted at 4.5 Ga, followed by development of the global lunar magma ocean. The primary lunar crust is composed by ferroan anorthosite which was produced by flotation of plagioclase during crystallization of the LMO. However, the mafic minerals, coevally crystallized with the plagioclase, sank to the base of the LMO due to their high density, and made up the main part of the lunar mantle, which served as the source during later mare basaltic magmatism.

根据这一年代资料，结合对月岩样品进行的短半衰期Hf-W与Sm-Nd同位素体系的研究结果，认为月球大致形成于45亿年，其后开始由岩浆海导致的内部核－幔－壳的分异，岩浆结晶的低密度斜长岩构成最初的月壳，而密度大的岩石构成月幔，而此月幔则成为后来月海玄武岩的主要岩浆源区。

In this paper, a series of lunar map projection formulas are deduced including azimuthal projections, cylindrical projections and conical projections. The lunar map projections software is compiled. By caculating lunar map projection distortions, their projection distortion rules are found. Base on the lunar exploration mission, the lunar map projection scheme is given in this paper. The azimuthal conformal projection or the circumcenter perspective azimuthal projection is usually used in small areas, especially in two poles. When the whole map of the moon is needed, the azimuthal conformal projection or the circumcenter perspective azimuthal projection is used within 10° in the poles, and the traverse tangent cylindrical conformal projection or the normal secant conical conformal projection can be used in else areas, furthermore, band-division is necessary to reduce the projection distortion.

Dhofar 1180 is a unique lunar meteorite that differs petrographically and geochemically from all other lunar meteorites and lunar samples.It comes from a region on the lunar surface that has not been sampled by any other known lunar rocks.

Dhofar 1180的矿物学、岩石学和微量元素地球化学特征与已知的月球陨石和月岩样品有明显的差异，它来自月球表面的一个新的未知地区。

According to authors' understanding on the density contrast of the lunar crustal and mantle materials, depths of typical mascons were estimated using various approaches. The estimations indicate that the mascon in Mare Orientale may caused by a lunar mantle plum, a basaltic lava with high density.Key words lunar gravity; mare; Mascon; clementine; lunar prospector

从宏观角度看，月球布格重力异常与月球地形起伏是相关的，统计结果表明它们呈弱负相关，从均衡角度来说，在月球停止大规模内部物质运动之前，月球壳幔可能已基本达到均衡；从Mascon深度估算结果来看，一些大型的Mascon基本属于玄武岩浆&充填&型的，少数Mascon可能与月幔柱有关，如东方海Mascon。

From the results, we presume the Lunar interior solidified 3 billion years ago, massive planetoids' strike caused the unevenly distribution of metallic elements, made the metallic abundance in the surface of Lunar highland lower than Lunar mare generally, and lead to the formation of craters on the Lunar surface.

由此推测30亿年前月球内部逐渐固化，大量小行星对月表岩石频繁的撞击导致金属元素分布不均衡，使金属元素在月球高原地带普遍含量低于月海，同时也形成了现在我们看到的遍布月表的环形山。

During the New Moon (the 1st of a lunar month) and the Full Moon (the 15th of a lunar month) when the Earth, Moon, and Sun lie in a straight line, the solar and the lunar tides overlap and the sea-level pressure is lower than the mean at the Airport, because the tide-producing force induced by the Sun and Moon reaches maximum. On the other hand, during the First Quarter (the 7th day of a lunar month) and the Last Quarter (the 21st of a lunar month) the Sun-Earth's and the Moon-Earth's relative positions are perpendicular to each other with respect to Earth, the solar and the lunar tides interfere mutually, the Airport sea-level pressure is greater than the annual mean due to the tide-producing force reaching minimum.
