【摘要】：在月球哥白尼纪撞击坑的底部发育有很多小型链状坑.这些链状坑的形态较小,以至于很少有月球探测器能探测其完整的细微形态.结合月球轨道器(Lunar Orbiter)、月球勘测轨道飞行器(Lunar Reconnaissance Orbiter(LRO))、月球女神(Kaguya)和嫦娥一号的相机数据,该文选择了月球上各种地形上的5个大型哥白尼纪撞击坑以研究月球哥白尼纪撞击坑底部发育的链状坑的成因.首先,通过在高清照片上分析这些链状坑的形态特征和分布方式,认为月球哥白尼纪撞击坑底部发育的链状坑是由于月表以下存在的岩浆活动而形成的;然后,结合月壤厚度数据,此模型的科学性得到了进一步的认证和讨论;在哥白尼纪撞击坑的底部可能依然有正在发育的链状坑存在.最后讨论了链状坑成因模型的局限性及其研究意义.
[Abstract]:At the bottom of the Copernican crater on the moon, there are many small chain craters. So few lunar probes can detect their complete nuances. Combined with camera data from the lunar orbiter Lunar Orbiter, the Lunar Reconnaissance Orbiter Orbiter, the Moon Goddess Kaguya) and Chang'e I, In this paper, five large Copernican impact craters on various terrain on the Moon are selected to study the origin of the chain craters at the bottom of the Copernican impact craters on the Moon. By analyzing the morphological characteristics and distribution patterns of these chain-like craters in high-definition photographs, it is concluded that the chain-shaped craters developed at the bottom of the Copernican impact crater were formed by magmatic activity below the lunar surface, and then combined with the lunar soil thickness data. The scientific nature of the model has been further verified and discussed, and there may still be a developing chain crater at the bottom of the Copernican impact crater. Finally, the limitations of the genetic model of the chain-shaped crater and its significance are discussed.
