常見(jiàn)例句

雙語(yǔ)例句

• What is the lightest element on Earth, with no stable isotope?
  地球上沒(méi)有穩(wěn)定同位素的最輕的物質(zhì)是什么？
• The highest known magic number for neutrons alone is 126. Lead, with 82 protons and 126 neutrons, is thus “doubly magic” and the heaviest stable isotope in the periodic table.
  目前已知的最大中子數(shù)是126，82個(gè)質(zhì)子和126個(gè)中子組成了元素周期表中最重最穩(wěn)定的同位素。
• Although the easier ionization of radon leads one to expect the most extensive chemistry for that element, the high instability of even the most stable isotope has severely limited studies of it.
  氡容易離子化，這讓人期望，該元素有最廣泛的化學(xué)反應(yīng)，但是，這個(gè)元素最穩(wěn)定的同位素也極不穩(wěn)定，這使氡的研究受到了嚴(yán)重的約束。

權(quán)威例句

• The uranium in the cake is almost entirely the stable isotope uranium 238.
