自古以来,人们把地球内部视为监禁严惩人间生前作恶多端歹徒和宗教叛逆者的地狱。14世纪意大利著名诗人但丁在被其政敌从家乡佛罗伦萨驱逐后,在其诗篇《地府》中诅咒他们下地狱倍受磨难。而在但丁的想像中,地狱分为若干错层式的球状结构,随深度的加深和范围的缩小,“刑罚”力度则加倍。但丁对“地府”的假想曾受到人们的嘲笑,但随着科学技术的发展,地球物理学家们发现,地球内部的构造与但丁的构思有某些相似之处。即地球内部分为外壳、地幔和地核三大层,核心为与太阳表面温度相同的铁质球状体,体积有月球般大,处在固态
Since ancient times, people have viewed the interior of the earth as a prison for harshness that punished the evil criminals and religious rebels who lived before the earth. In the fourteenth century, the famous Italian poet Dante, after being expelled from his hometown Florence by his political opponents, cursed them in hell in his poetic prefectures. In Dante’s imagination, hell is divided into several layers of spherical structure, with the deepening of the deepening and the narrowing of the scope, “penalty ” efforts are doubled. Dante’s hypotheses about “earth ” have been ridiculed, but with the development of science and technology, geophysicists have found that there are some similarities between the structure of the Earth and Dante’s concept. That is, the Earth’s interior is divided into three layers: the crust, the mantle and the earth core. The core is the iron sphere with the same temperature as the sun’s surface. The volume is moon-shaped,
