| 摘 要： | 提出了拟合消解方程y=C_0e(-kt)的直接寻优法。对27套农药残留试验数据的计算表明该方法的剩余平方和比经典方法和加权回归法的都小,其相关指数也都比后两者的更接近1。因此,直接寻优法是三种方法中效果最好的。

| Abstract: | This paper gives a direct optimal method of fitting the degradation equation y= C_0e~(-kt). With the caculation of 27 sets of experimental data, it is shown that the residual sum of aquares of this method is less than those of the traditional method and weighted re- gression method, and the related index of this method is closer to 1 than those of the other two methods. So, the direct optimal method is the best one among the three methods. |
