decrease of the deviation ratio of initial values, the deviation ratio of predicted and measured results gets smaller. It can be concluded that the closer their initial values, the better the results obtained.
ratios of predicted and measured results also have the relatively higher deviation ratios of their initial values (10.1–13.7 ). However, the deviation ratios of initial values of the other 14 pesticides were <10 , with a range of 0.1–9.1 . With the
