Synthesis of mesoporous aluminum phosphate with poly amido amine dendrimer as a template 樹(shù)形分子為模板劑合成介孔磷酸鋁
Rather the lion ' s share was trapped in aluminum phosphate minerals , which contain no uranium at all 相對(duì)的,大部份的氙被囚禁在磷酸鋁礦物中,這種礦物根本完全不含鈾。
After my colleagues and i had worked out in a general way how the observed set of xenon isotopes was created inside the aluminum phosphate grains , we attempted to model the process mathematically 在想通了觀察到的氙同位素大致如何在磷酸鋁顆粒中生成之后,我和同事就試圖用數(shù)學(xué)模式來(lái)仿真這個(gè)過(guò)程。
But even if nature could miraculously create a similar process on a microscopic scale , the mix of xenon isotopes in the aluminum phosphate grains we studied would have been different from what we found 但是,即使大自然能奇跡似的在微小尺度創(chuàng)造出類(lèi)似的過(guò)程,磷酸鋁顆粒中的氙同位素組成也會(huì)和我們所發(fā)現(xiàn)的不同。
Nature ' s fission reactors suggest the possibility of locking those waste products away in aluminum phosphate minerals , which have a unique ability to capture and retain such gases for billions of years 天然的核分裂反應(yīng)堆暗示著,將這些廢物鎖進(jìn)磷酸鋁礦物里的可能性,這類(lèi)礦物具有獨(dú)一無(wú)二的能力,可以捕捉并保存上述氣體達(dá)幾十億年之久。
When the reactor cooled down , the longer - lived xenon precursors ( those that would later spawn xenon 132 , 131 and 129 , which we found in relative abundance ) were preferentially incorporated into growing grains of aluminum phosphate 當(dāng)反應(yīng)堆冷卻下來(lái),氙的放射性母核中生命期較長(zhǎng)的,則被選擇性的包納進(jìn)正在成長(zhǎng)的磷酸鋁顆粒中,例如那些可以生成我們所見(jiàn)的大量氙132 、氙131 、氙129的物質(zhì)。
