A density functional and ab initio theory investigation on M@B9 and M@B10 molecular wheels containing planar nona-and deca-coordinate heavy group 11, 12 and 13 metals (M=Ag, Au, Cd, Hg, In, Ti) has been performed. These unusual clusters all prove to be true minima on the potential energy surfaces of the systems and σ+π double aromatic in nature. The first two vertical one-electron detachment energies of M@B-10 (M=Ag, Au) anions and first two ionization potentials of M@B9 (M=Ag, Au) and M@B10 (M=Cd, Hg) neutrals were calculated to aid future experiments. The cluster complexes designed in this work may expend the domain of planar hyper-coordinate elements to include heavy group 11, 12, and 13 metals and serve as interesting candidates to be targeted in experiments.

A density functional theory and wave function theory investigation on the possibility of carbon-free phosphametallocenes [P3MP3]2-and arsenametallocenes [As3MAs3]2- (M=Ni, Pd, Pt) is presented in this work. Staggered singlet D3d [E3ME3]2- (E=P, As)-the smallest inorganic metallocenes possible to construct-proved to be the global minima of the heptaatomic sys- tems and may be targeted in future experiments. Cyclo-P3- and cyclo-As3- turned out to possess similar aromaticity to cyclo-P5- and cyclo-As5- and may serve as effective ligands to sandwich a wide range of transition metals. The first vertical electron detachment energies of Cs [E3ME3]Li+ monoanions with a staggered [E3ME3]2- sandwich core were predicted to be between 2.7 and 2.9 eV; the extent of stabilization by Li+ suggests that such materials be viable targets for experimental characterization.

本研究以自我、个性为内容辅以专家讲座展开了自我认知训练干预,对象为29名随机抽取的中学教师,干预实施持续了两个学期,测查工具为SCL-90、SDS、SAS。结果表明:干预后所有各项的均数均有下降,且除偏执因子外均达P<0.01显著意义水平;干预在偏执因子上效果较为一般,在"躯体化"、"恐怖"、"精神病性"、"饮食睡眠"、"敌对"、诸因子上效果良好,在强迫、人际敏感、焦虑因子上效果更为良好;总之,自我认知干预对教师心理健康具有积极影响,此影响在不同心理因子上会有不同效果。

在文学翻译中,译者主体性的发挥从一开始就受到意识形态的制约,特定的社会文化环境的制约会通过译者反映到译作中,同时也是解释特殊翻译现象的理据。译入语读者也对译者的主体性起着制约作用,但这种积极的制约往往促使译者做出创造性的努力。通过翻译事实和具体的译例,论述宏观环境下译者主体性所受的三个外部制约。
