在很多神话传说中,地下世界都被描述成燃烧着烈火的地狱。近期,英国杜伦大学的科学家们证实,这很可能是真的。长期以来,科学家们都认为地球形成时,铁和镍等重金属下沉到地核,而较轻的元素,如氧、硅、铝等则大多集中在地幔和地壳。但让科学家们疑惑的是,地核质量太轻,不可能完全是由金属构成的,应该还有其他的非金属物质。近期,英国杜伦大学的科学家研究发现,地核中除了铁和镍,还蕴藏着大量的硫磺,并推算出这些硫磺的质量可 In many myths and legends, the underground world is described as a hell burning with fire. Recently, scientists at Durham University in the UK have confirmed that this is likely to be true. For a long time, scientists believed that when the earth formed, heavy metals such as iron and nickel subsided to the core, while lighter elements such as oxygen, silicon and aluminum were mostly concentrated in the mantle and crust. But scientists are puzzled that the quality of the Earth’s core is too light and can not be entirely composed of metal, there should be other non-metallic substances. Recently, a study by scientists at Durham University in the United Kingdom found that in addition to iron and nickel in the core, there is also a large amount of sulfur and the quality of these sulfur
