集體躍遷 的英文怎麼說
中文拼音 [jítǐyuèqiān]
集體躍遷
英文
collective transition-
The coupling admixes the particle and collective degrees of freedom in such a manner as to partially transfer the one-particle transition strength onto the collective modes.
耦合使粒子和集體自由度按這樣的方式混合，即使單粒子躍遷強度部分地轉變到集體模式中。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。In 106mo, a total of 31 new levels and 68 new transitions were identified with spin up to 16 ?, and a total of 8 rotational bands, among which, four of them are new ones, have been observed
在~ { 106 } mo中識別了31條新能級和68條新躍遷，共識別了8個集體轉動帶，其中有4個帶是新識別的，最高自旋態擴展到16
