查询词典 serial correlation coefficient

The reaction kinetics was studied by selecting control-step method as well as modified Debye-Hückel activity coefficient model and Bromley osmotic coefficient model. The results show that the reaction order is 2 and apparent reaction activation energy 85.8 kJ/mol, and the reaction is mainly controlled by precipitation of KB5O8?4H2O.

采用选取控制步骤法并引入修正的Debye-Hückel活度系数模型和Bromley渗透系数模型研究了该反应的动力学的影响规律，得出反应级数为2，表观反应活化能为85.8 kJ/mol，反应主要受四水五硼酸钾晶体析出的控制。

In this thesis, Water Solubility, 1-Octanol/water Partition Coefficient, molecular Total Surface Area, Aqueous Activity Coefficient, Henry Law's Constant and gas chromatogram relative retention times for biphenyl and its 209 chlorinated congeners were studies with holographic QSAR techniques and highly predictive QSAR models were developed. An internal validation (cross-validation) and external validation were performed to evaluate the predictivity and robustness of the HQSAR models. Based on these highly predictive QSARs, the corresponding data of 5 properties of all these pollutants were presented.
