Parameters obtained from topological indices and quntitative calculation regress with the biodegradation rate constants;hence,the established binary mathematical model has good correlation,robustness and reproducibility.

• 利用拓扑指数和量化计算得到的参数共同与取代苯甲酸的生物降解速率常数回归；建立的二元数学模型具有很好的相关性.；并且；该模型表现了很好的稳键性和可重复性
