Similar to the oxidation process of Si(111)-7×7 by water,the gradual insertion of S atom into Si_a-Si_s backbond is possible to occur,and the insertion pathway,which begins with directly destroying Si_a-Si_s backbonds by a foreign H_2S molecule,remains more favorable.However,when H_2S attacks at the Si_a site to split Si_a-Si_s backbond with its S or H atom,there is no distinct thermodynamical and kinetical difference between these two attacking behaviors,whereas Si_a-Si_s backbond is easilier broken when H_2O attacks at the Si_a site with its O atom.This mainly lies in the fact that the electronegativity of oxygen is larger than that of sulfur.
5类似于H_2O对Si(111)-7×7的氧化历程,S原子逐步插入Si_a-Si_s键是可以发生的,且H_2S直接打开Si_a-Si_s键进而使S原子插入的途径仍是动力学上较为有利的,但H_2S以S或H原子进攻Si_a位从而打开Si_a-Si_s键的两种反应机制在动力学和热力学上并没有表现出明显的差别,而当H_2O以O原子进攻Si_a位时,Si_a-Si_s键则较容易断裂,这应归因于O的电负性比S大。

On the one hand,PH_x(x=2,1) can insert into the Si-Si backbond at elevated temperature,and a surface Si=P or a subsurface Si_3P unit was formed via subsequent H_2 liberations.On the other hand,the PH_2 species adsorbed on the Si_r site may completely dissociate across the other two unsaturated adatoms,and P adsorbed on the Si_r site may desorb in P_2 gas form at high temperature.
一方面,在高温下PH_x(x=2,1)可插入Si-Sibackbond,继而经过脱H_2步骤形成表面Si=P单元或次表面Si_3P单元;另一方面,吸附在Si_r位上的PH_2也可能在相邻的另两个Si adatom上实现后两个P-H键的解离,在高温下,吸附在Si_r位上的P可能以P_2的形式脱附。

In this method onlydihedral angles were selected as independent variales,a proper target function was minimized by loacl-to-globular optimization,thus these dihedral angles andthe coordinates of six kinds of the backbond atoms (N,HN,Cα,IIα,C′,0) were calculated.
这种方法把肽平面之间的二面角当做独立变量,通过从局部到整体逐渐最优化的方法使适当构造的目标函数最小,计算出这些二面角,以及主链每个残基上六种原子N、H%%^^N%%^^、C%%^^α%%^^、H%%^^α%%^^、C′、O的空间坐标,绘出蛋白质分子的溶液三维结构图案,并成功地把这种方法编写成计算程序DISNMA,且以碱性胰蛋白酶抑制剂为标准结构,得到了很好的验证。

For the oxidation channel from OH group migration to O atom insertion,the activation energy barriers for OH migration are 58.4,65.3, and 79.2 kcal/mol,respectively,whereas those for O atom insertions beginning with directly destroying Si_a-Si_s backbonds by a foreign H_2O molecule are much lower,the respective values are 19.0,16.7,and 24.8 kcal/mol.
对于先经过OH迁移致使O原子插入Si_a-Si_s backbond的氧化途径,OH迁移所克服的能垒依次为58.4、65.3和79.2 kcal/mol,而H_2O以O原子进攻Si_a位来打开Si_a-Si_s键进而使O原子插入的能垒则相对较低,仅为19.0、16.7和24.8 kcal/mol。
