采用支持向量回归方法建立了取代芳烃对斜生栅列藻的急性毒性值(-lgEC_50)与分子体积(v)、近似表面积(ASA)、网格表面积(GSA)、水化能(HE)、疏水系数(LogP)间的定量关系,用留一法预报了取代芳烃对斜生栅列藻的急性毒性值(- lgEC_50),相对误差绝对值平均为5．803％,其结果优于偏最小二乘法建模所得结果(相对误差绝对值平均为9．49％)。
Acute toxicity value (-lgEC_50), molecular volume (v), approximate surface area (ASA), surface area of cells (GSA), hydration energy The results showed that the absolute value of the relative error was 5.803%, which was better than the partial least The results of the two-factor modeling (relative error absolute average of 9.49%).
