提出了多环芳烃的分配系数 (Kow)与其二阶连接性指数 ( 2 x)之间的定量关系方程 ,估算了 4 2个多环芳烃的Kow,估算值与实验值吻合 ,相关系数R =0 .991 4 .
A quantitative relationship equation between PAH (Kow) and second-order connectivity index (2 ×) was proposed. The estimation of Kow for 42 PAHs was in good agreement with the experimental data. The correlation coefficient R = 0 .991 4.
