解释可能是在地球的地幔中,这是在构造板块下面的岩石层,向下延伸超过1800英里到地球铁芯的外边缘。
Computer simulations of this impact show that both of the objects would melt in the impact and the dense core of the impactor would fall as molten rock into the liquefied iron core of Earth.对这次撞击的计算机模拟显示,这两个物体都会在撞击中熔化,而撞击者稠密的核心会以熔融岩石的形式落入地球的液化铁芯中。
A new moon-rock study suggests the satellite has an iron core.月球可能比科学家原先认为的更要“地球化”。 一份最新的月石研究报告称,月球有一颗“铁心”。
I will post on auction the field coil and iron core magnet on auction later. However, to replace the magnet require technical skill and tool.我随后会拍卖励磁和导磁柱,但是,改变磁路需要点技术和工具。
