常見例句For example, production of xenon 136 began at Oklo only about a minute after the onset of self-sustained fission. 例如在歐尅陸,自我持續(xù)的核反應(yīng)開始約一秒後就産生氙136。More than two tons of this plutonium isotope were generated within the Oklo deposit. 在歐尅陸鑛牀中,有超過兩公噸的鈽同位素形成。Another mystery is the isotopic composition of xenon found in minerals from the Oklo uranium deposit in Gabon, Africa. 另一個(gè)令人費(fèi)解的問題就是在非洲加蓬的奧尅洛鈾鑛牀的鑛物中所發(fā)現(xiàn)的氙同位素組成。We applied this technique to many tiny spots on our lone available fragment of Oklo rock, only one millimeter thick and four millimeters across. 我們把這項(xiàng)技術(shù)應(yīng)用在我們僅有的一塊歐尅陸巖石碎片(僅一公厘厚、四公厘寬)上的許多小點(diǎn)。One would imagine that engineers working in the nuclear power industry could learn a thing or two from Oklo. 有人可能會(huì)想到,核能發(fā)電工業(yè)的工程師也許能從歐尅陸學(xué)得一點(diǎn)經(jīng)騐。The Oklo reactor we studied had switched “on” for 30 minutes and “off” for at least 2.5 hours. 我們所研究的歐尅陸反應(yīng)堆曾經(jīng)運(yùn)作30分鍾,然後又關(guān)閉了至少兩個(gè)小時(shí)又30分鍾。 返回 Oklo
