The discovery could help us to better understand how our world formed.
Lead researcher Eiji Ohtani from the University of Tohoku told BBC News: "We believe that silicon is a major element - about 5% [of the Earth's inner core] by weight could be silicon? dissolved? into the iron-nickel? alloys ."
這一發現可能有助于我們更好地了解世界是怎么形成的。來自東北大學的首席研究學者Eiji Ohtani告訴BBC新聞網：“我們認為，硅是一種主要元素，（地核）大約5%的重量是溶于鐵-鎳合金中的硅”
