相对论粒子在晶格中相关散射

本文采用与粒子运动纵向分量相同的坐标系来考察相对论粒子同晶格原子相关碰撞及其量子辐射。通过相对论变换,使三维运动问题转化为两维问题(轴向沟道运动)或一维问题(面沟道运动),从而大大简化了计算步骤,并以几种典型的相互作用势,讨论了沟道轻粒子在晶格中运动时束缚态之间的跃迁。用Moliere势计算出MeV电子在晶格轴向沟道中运动时发射与韧致辐射不同的量子辐射谱的特征,与实验结果相当符合。     

Regularities of formation and lattice distortion of perovskite-type compounds

Based on 489 known perovskite-type complex oxides and a number of other type complex oxides, the pattern recognition-atomic parameter method is adopted to find regularities of the formation and the lattice distortion of the perovskite structure. It has been found that the restriction on Goldschmidt's t factor constitutes only a necessary but not a sufficient condition to form perovskite-type compounds. A more effective mathematical model, which can precisely sum up the regularities of the formation, the lattice distortion,and the cell constants of known perovskite-type compounds and reliably make corresponding predictions on unknown compounds, can be set up by integrating multiple atomic parameters such as ionic radii, ionic valency, and Basanov's electronegativity of constituent elements. Based on it, an intelligent database has been implemented. Its prediction accuracy is tested by eight newly discovered perovskite-type compounds such as Eu(Mn0.5 Ni0.5)O3, etc. (they are not included in the database during the test). The prediction resuits are in agreement with experimental facts.     

非离子表面活性剂溶液自聚集行为的Monte Carlo模拟

用MonteCarlo方法模拟了非离子表面活性剂溶液形成胶束的情况。考察了链长、分子间相互作用能对表面活性剂的聚集能力、聚集形态的影响。模拟结果显示:尾基-溶剂间、尾基-尾基间的作用能越大,越易形成胶束,所对应的临界胶束浓度(CMC)越小,而头基-溶剂间的作用能对胶束的形成影响不大。CMC随表面活性剂链长的增加而降低。胶束在溶液中的形成过程经历了形成大胶束→大胶束分散为小胶束→小胶束再长大的过程。
