Autocorrelation topological study on the acute toxicities of substituted aromatic compound s;2. The autocorrelation topological researches on slow and acutetoxicities of substituted aromatic compound s to scenedesmus ubliquus, rat and so on;3. Results show that the SW and KOW of the substituted aromatic compound s could be better forecasted at AM1 level.

应用分子力学方法MM+和半经验量子化学AM1、MNDO和PM3法得到了54种取代芳烃的优势构象，在此基础上结合分子图形学技术，获得相应优化构象的电子结构参数和几何结构参数，并将这些参数与取代芳烃的辛醇/水分配系数和溶解度相关联。

This happens in a so called reaction center inPhotosystemⅡ, where a tetrameric chlorophylls (P680) absorb the solar light andinitiate photoinduced electron transfer reaction to the acceptors, quinone A and B. Thephoto-oxidized P680 retrieves the electron from a Mn4Ca cluster via a tyrosine, thelatter components are also called oxygen evolving center. After 4 photo-processes, twomolecular water are oxidized to a molecular oxygen.

在光系统二的活性中心，叶绿素P_(680吸收太阳光，将电子传递给电子受体、醌A和醌B，同时光氧化的P_(680)~+从释氧中心中得回电子(通过Tyr_z氧化Mn4Ca簇)，经过四次光诱导电子转移，两分子水最终被氧化生成一分子氧气。
