  2. 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。
