能增生的鈾
英文
fertile uranium-
In analyzing the neutron active detection, the neutron multiplication in the nuclear warheads induced by outer neutron source with different neutron energys is studied with numeral simulation, and the feasibility of through counting neutrons to determine the presence of high enrichment uranium ( heu ) in nuclear warhead has been proved. the method of detecting the warhead which contains heu pit by counting the released neut rons whose energy is higher than that of source neutron is studied. the feasibility of this method has been studied
對幾種主動探測核彈頭方法進行的研究中，首先對不同能量各向同性外源中子照射核彈頭的中子增殖行為進行了數值模擬，檢驗了用外源中子照射核彈頭后，通過測量瞬發中子在核彈頭中的增殖量，來證明核彈頭中高濃鈾存在的可行性；研究了用能量低於1mev的外中子源照射核彈頭，用測量核彈頭中裂變產生的高於源中子能量中子數的方法探測核彈頭，通過數值模擬分析了可行性。And with more and more nuclear material being processed and reprocessed ? as mostly uranium - laden reactor fuel - rods turn into mostly plutonium - laden spent fuel ? the possibilities for theft or diversion can only grow
而且，隨著越來越多的核原料經過加工和再加工? ?通常是含鈾的反應堆燃料棒轉變成了含鈈的核廢料? ?發生盜竊或轉移的可能性只會增大。There are distinct changes about shifts or intensity in bulk plasmon, surface plasmon, and interband electron transitions losses as a result of oxidation of specimens, and adsorption and oxidation processes can be studied through these changes. at room temperature, the formation of oxide layers on uranium and uranium - niobium alloys were found to occur rapidly upon exposure to oxygen, and the resultant oxide in each case was near - stoichiometric uo2. due to formation of niobium oxide in uranium - niobium alloys, the diffusion of o ~ ( - ) ( o ~ ( 2 - ) ) and u ~ ( 4 + ) in the interface region was prevented, and the corrosion resistance of uranium - niobium alloys to oxygen is greatly enhanced by alloying with niobium
研究結果表明：清潔表面鈮和鈾的體等離子體振蕩所造成的電子能量損失的實驗值與理論計算值較為符合；隨著氧化程度的加劇，表面等離子體（ sp ） 、體等離子體（ bp ）以及價帶電子躍遷所造成電子能量損失的譜峰發生了明顯的連續偏移或強度的變化，這些變化可以用來分析鈾及鈾鈮合金的初始氧化過程；室溫下，鈾及鈾鈮合金很容易與氧作用，最終結果，鈾僅氧化為二氧化鈾，另外，在鈾鈮合金氧化過程中，因為有鈮的氧化物存在，不利於氧和鈾在界面擴散，增強了鈾鈮合金抗氧化性能； eels能獲得樣品表面的信息比aes更為表面，更為靈敏，但由於eels的譜線過于集中，主要在幾十ev以內，也有不容易區別和解譜的不足。
