The oxidation behviours of liquid tin with and without trace Ge at 250℃in atmo- sphere were studied by both observation and removing dross from the surface periodically.

采用观察液态Sn表面氧化行为和刮取表面氧化渣的方法,研究了微量元素Ge对液态Sn在大气和250℃条件下表面抗氧化性能的影响,并与纯Sn的氧化行为进行对比;利用X射线光电子能谱仪(XPS)、扫描电子显微镜(SEM)研究了合金表面元素的含量、价态,及合金氧化后的表面形貌。

Based on Atomic and Molecular Reaction Statics and Group theory, the basis sets SDD~(**) for Tin and 6-311g~(**) for H_2, and density functional (B3P86) method have been used to calculate energy E, heat capacity C_v, entropy S of hydrogen isotopes and their Tin compounds.

根据原子分子反应静力学与群论,确定了H2、D2和T2的基电子状态为1∑+g(D∞v),SnH、SnD和SnT的基电子状态为2∑+(C∞v)。
