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。

The effects of several components in the culture medium on Lithospermum erythrorhizon cell growth and secondary metabolite synthesis were studied, as well as structural dynamic model. The two-liquid-phase culture of Lithospermum erythrorhizon was carried out by choosing the proper organic solvent as the second phase. The bioactive carrier for adsorption was prepared and the condition of cell immobilization was determined. We combined the technique of two-liquid-phase culture and immobilization to carry out the culture. We chose the suitable type of reactor, studied its characteristics and results of cell culture using this reactor. The fed-batch operation was also studied on the basis of twoliquid-phase culture and immobilization used in culture in the reactor.

As a supplement of conventional CT, CT perfusion imaging can reveal the perfusion informations of tissue or organs, such as hemodynamics, microcirculation status. It is helpful not only in finding morphologic changes, but also in providing functional and metabolizable information about the circulation parameters of hepatic diseases. So, it is valid for studying liver disorders by providing functional information, especial for the differential diagnosis and assessment for therapeutic response.
