【摘要】 介绍了灰色Verhulst模型的原理与检验方法,以毒死蜱在苹果中的残留量作为原始数据序列,利用Matlab编程为实验平台,建立了瓜果蔬菜中农药残留量的Verhulst预测模型,并与负指数模型进行比较。结果表明:所建的Verhulst预测模型具有较高的精度,可以准确的预测出瓜果蔬菜中的农药残留量,为人们的健康饮食提供科学的依据。更多还原

【Abstract】 In this paper,we introduced the principles and test methods of Grey Verhulst Model,Chlorpyrifos residues in apples as the original data sequence,established Verhulst predictive model of pesticide residues in fruits and vegetables using Matlab.The results show that Verhulst predictive model of pesticide residues in fruits and vegetables has higher precision and it can predict the residues in fruits and vegetables accurately,provide a scientific basis for people to a healthy diet.更多还原
