对苯甲酰环己二酮类除草剂进行了多元线性回归及BP人工神经网络研究,结果表明电荷转移复合作用是影响其除草活性的主要因素。苯环2位是拉电子基,3位是给电子基有利于提高除草活性。
Multivariate linear regression and BP artificial neural network were carried out on the benzoylcyclohexanedione herbicides. The results showed that the charge-transfer complex effect was the main factor affecting its herbicidal activity. The benzene ring 2 is the electron-withdrawing group and the 3-position is the electron-donating group, which helps to improve the herbicidal activity.
