摘要
用改进的Ｒａｙｌｅｉｇｈ模型Ｃ＝ａｘａｅｂｘ２描述农药的降解规律，并给出其参数估计方法，以残差平方和作为优化标准，结果表明：改进的Ｒａｙｌｅｉｇｈ模型优于常用的指数模型，具有误差小，使用方便的优点，为研究农药残留规律提供一种新方法。
The degradation of pesticides was described by a modified Rayleigh model,C=axaebx2,and the method to estimate parameters of the model was also developed.The modifiedRayleigh model was better than commonly used index model for its small error,which pro-vides a convenient method to investigate the chemical remains patterns.
