uranium cycle
解釋
鈾循環-
Uranium has been redistributed by biological processes as well as in the sedimentary cycle.
由於生物作用，以及沉積旋迴，鈾發生重新分佈。 -
The author and two colleagues recently used measurements of xenon gas ( a product of uranium fission ) to deduce that one of these ancient reactors must have operated with a duty cycle of about half an hour on and at least two and a half hours off
作者與兩位同事最近透過氙氣（鈾的核分裂產物）的測量推測，這些遠古反應器其中之一必定曾經以運作半小時、關閉兩小時半的周期進行核反應。 -
Second, there appears to be ample uranium at reasonable cost to sustain the tripling in global nuclear power generation that we envisage with a once - through fuel cycle for the entire lifetime of the nuclear fleet ( about 40 to 50 years for each plant )
其次，地球上似乎還有充份的鈾，能以合理的價格去維持未來全球核能電廠的營運這里所設想的情況是，這些電廠數目在未來將增加兩倍，而且在其整個壽命（每個電廠約40 ~ 50年）中都是使用單次燃料循環。 -
Microbial mineralization is outlined, the effects of thiobacillus, sulfate - reducing bacteria, iron - reducing bacteria, nitrifying bacteria, denitrifying bacteria, and various bacteria that play the roles during the bio - mineralization of uranium and that correlated with the cycle of geological elements were also introduced in this article
摘要概述了微生物成礦作用，並介紹了硫桿菌、硫酸益還原菌、鐵細菌、硝化細菌、反硝化細菌等各種細菌在與鈾的生物成礦過程相關的地質元素循環中所起到的作用。 -
Guided by the basic theory of high - resolution sequence stratigraphy, and based on the core observation, the analysis of chemical composition of rocks, and data of natural potential logging and apparent resistivity logging, authors have set up the high - resolution sequence stratigraphy framework of the ore - hosting yaojia formation, and discussed the relation of the stratigraphic structure of the middle cycle, as well as the paleotopography, the micro - facies to the formation of uranium deposit
在高解析度層序地層學基本理論指導下，筆者通過巖心觀察、巖石化學組分分析、自然電位及視電阻率測井等手段，建立了賦鈾巖系姚家組高解析度層序地層格架，探討了中期旋迴內地層結構、古地形和沉積微相與鈾礦床形成的關系。 -
Iran has previously threatened to break off all cooperation with the u. n. nuclear agency and resume uranium enrichment - the most sensitive phase of the atomic fuel cycle - if the security council steps into the dispute
伊朗先前威脅說，如果安理會介入爭端，伊朗就終止與國際原子能機構的所有合作，並恢復濃縮鈾提煉。濃縮鈾提煉是原子燃料循環中最敏感的階段。 -
Some countries, most notably france, currently use a closed fuel cycle in which plutonium is separated from the spent fuel and a mixture of plutonium and uranium oxides is subsequently burned again
有些國家，尤其是法國，使用一種封閉式燃料循環，能將鈽從核廢料分離出來后，與氧化鈾混合再次當成燃料。
