摘  要:
采用气相色谱法测定抗蚜威在黄瓜果实中的残留量数据,建立指数负增长函数模型、Rayleigh动态模型、灰色预测GM(1,1)模型等不同类型的数学模型,然后对其进行拟合度检验,结果表明:灰色预测GM(1,1)模型的预测拟合度最好,农药在生态环境中的降解过程是一个典型的灰色系统,应用灰色预测GM(1,1)模型可以很好地模拟抗蚜威在生态环境中的残留消解动态.

摘  要:
The different types of mathematical models,such as the exponential negative growth function model,Rayleigh dynamic model and GM(1,1) model were established on the basis of the pirimicarb residual content in cucumber fruits by gas chromatography,and their fitness were tested.The results showed that the fitness of grey predictive model is the best.And,because dispelling process of pesticide in ecological environment is a typical grey system,the grey predictive model could simulate the dispelling dynamic of the pirimicarb residue in ecological environment better.
