界面扩散 meaning in English
interfacial diffusion
Examples
- But long time anneal will cause thermal degradation the whole spin - valve because of interlayer diffusion
但长时间的高温退火处理将会造成自旋阀其它各层之间的界面扩散，影响其性能。 - 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
研究结果表明：清洁表面铌和铀的体等离子体振荡所造成的电子能量损失的实验值与理论计算值较为符合；随着氧化程度的加剧，表面等离子体( sp ) 、体等离子体( bp )以及价带电子跃迁所造成电子能量损失的谱峰发生了明显的连续偏移或强度的变化，这些变化可以用来分析铀及铀铌合金的初始氧化过程；室温下，铀及铀铌合金很容易与氧作用，最终结果，铀仅氧化为二氧化铀，另外，在铀铌合金氧化过程中，因为有铌的氧化物存在，不利于氧和铀在界面扩散，增强了铀铌合金抗氧化性能； eels能获得样品表面的信息比aes更为表面，更为灵敏，但由于eels的谱线过于集中，主要在几十ev以内，也有不容易区别和解谱的不足。
