【摘要】:目前,对月表的线性构造研究得很少,对月表月海、月陆分布的起因同样不明."嫦娥一号"遥感探测表明:月表大部分线性构造集中分布于月球面向地球的正面(48°W-54°N),统计的86条月表线性其走向主要是N-S、NE-SW、NW-SE;22个月海大部分位于月球正面,且其中的20个月海分布在中低纬度(33.7°S-32.8°N).基于我们之前对地球板块动力学的认识,对月表的线性构造及月海分布的动力学解释是:引潮力引起了月表南北向的挤压和东西向的拉张,产生了N-S方向的挤压性破裂和在NW-SE,NE-SW方向产生的剪切性质的破裂,且月球正面所受的引潮力比背面大,所以线性构造多位于月球正面.通过引潮位ψ=Gmr0∑nn=2(ar0)nPn(cosv)的分析,月球在公转过程中,中低纬度受到的引潮位更大,在引潮力-重力共同作用下,形成的月球正面不仅壳薄而且裂隙多,岩浆向月壳薄弱的地方喷涌,形成分布在月球正面中低纬度的月海.
[Abstract]:At present, little research has been done on the linear structure of the lunar surface, and the origin of the distribution of the lunar surface and the lunar land is also unknown. " The Chang 'e-1 "remote sensing survey shows that most of the linear structures on the lunar surface are concentrated in 48 掳W-54 掳NV of the lunar front facing the Earth, and the main linear strike of the 86 monthly charts is N-SNNE-SWN NW-SE.The 22 lunar seas are mostly located on the front side of the moon. And 20 of them are distributed in 33.7 掳S-32.8 掳N ~ (-1) in middle and low latitudes. Based on our previous understanding of the dynamics of the Earth's plate, the dynamic interpretation of the linear structure of the lunar surface and the distribution of the lunar sea is as follows: the tidal force causes the compression of the lunar surface from the north to the south and the extension from the east to the west. The compression rupture in the N-S direction and the shear rupture in the NW-SEN NE-SW direction are produced, and the tidal force on the front of the moon is larger than that on the back, so the linear structure is mostly located on the front of the moon. Based on the analysis of the tidal level 蠄 Gmr0 鈭,
