Transition probabilities, oscillator strengths, and lifetimes of configurations, multiplets, and individual lines for many-electron atoms and ions are studied employing the WBEPM theory. Transition probabilities and oscillator strengths for alkali metal atoms, alkaline-earth elements Be, Mg, Be , and Mg , carbon atoms and its ions , nitrogen atom and its ions , oxygen atoms and its ions , fluorine atom, Ne , and IB elements are calculated. Lifetimes of C, N, and O atoms are evaluated as well.

运用WBEPM理论对多电子原子和离子的组态、谱项和能级间的跃迁几率、振子强度以及辐射寿命进行系统地研究,计算了碱金属原子、碱土金属的Be、Mg原子及其一价离子、C原子及其离子、N原子及其离子、O原子及其离子、F原子、Ne离子和重金属IB族原子的跃迁几率和振子强度以及C、N、O原子的辐射寿命。

The Zn-Ti distances are 0.369 nm and 0.335 nm for the single-corner adsorption mode and double-corner adsorption mode, respectively. Therefore, the EXAFS fitting data, R1=0.371 nm, R2=0.332 nm, can be well distinguished for SC and DC mode respectively. The calculation results also showed that the optimized Zn-O average distance of Zn-O tetrahedron is about 0.200 nm, which agree with the EXAFS results.

用DFT方法对四配位水合Zn离子在簇Ti2O11H14上进行优化后发现,四配位的Zn-O平均距离为0.200nm;外层Zn-Ti结合存在两种稳定的吸附模式:单角吸附模式和更加稳定的双角吸附模式,其Zn-Ti距离分别为0.369和0.335nm。

The results indicate that improving temperature to reflux, using low polarity solvent as dispersion medium and proper molar ratio of tetrabutyl titanate to stearic acid can bring out good modification. The function of tetrabutyl titanate is to react with the surface hydroxyl groups and adsorbed H2O on the powder particles to produce new binding sites such as M—O���Ti—OC4H9and M—O���Ti—OH, which can easily react with the carboxylic acid. As temperature increases from room temperature to reflux temperature, the reactions between RCOO- and Ti change from coordinate bonds to covalent bonds, which makes the carbon chains of stearic acids more strongly bound with the powder particles surface.

研究结果表明,提高处理温度、适当增加复合改性剂中硬脂酸的量并选用极性弱的有机溶剂可达到比较理想的改性效果;钛酸四丁酯的作用是与粉体粒子表面的羟基以及吸附水反应产生偶联点,如M—O—Ti—OH,这些偶联点易于与羧酸反应;在低温时RCOO-与偶联点的Ti之间以配合物的形式发生作用,在回流温度下处理时,主要发生酯化反应,使硬脂酸更牢固地嫁接到粉体粒子表面,改性效果更好。
