摘要
应用电性拓扑态指数(Ek)模拟分析了影响42种取代芳烃在活性污泥中的生化需氧量(BOD),建构了一个8变量的QSBR模型,其可决系数(R2)为0.531,估算标准误差为10.777,具有良好的稳健性与预测能力.
8 variables quantitative structure-biodegradability relationship (QSBR) model is established applying electrotopological state index (Ek ) simulation analysis of the biochemical oxygen demand (BOD) of 42 substituted aromatic compounds with activated sludge. The model determining coefficient(R^2) is 0. 531, and standard deviation is 10. 777, which possessed robustness and predictability.
