为实现鸭蛋白色中金霉素含量的快速预测，提高预测模型的准确性，采用导数同步荧光法和支持向量回归（SVR）建立鸭蛋白色中金霉素含量的预测模型。最后，利用支持向量回归机（SVR）对11个特征波长进行预测，预测模型的决定系数（R2）和预测均方根误差（RMSEP）分别为0.973和1.5011 mg/L，实验结果表明，该方法能满足鸭蛋白色中金霉素含量测定的要求。
To achieve the rapid prediction of aureomycin contents in duck egg white and improve the accuracy of prediction model,the prediction model of aureomycin content in duck egg white was developed with derivative synchronous fluorescence method and support vector regression(SVR).Firstly,three-dimensional synchronous fluorescence fingerprints and three-dimensional synchronous fluorescence spectroscopies within 280-400 nm were analysed,and 70 nm was selected as the optimum wavelength difference.Secondly,11 characteristic wavelengths were selected combined with siPLS and GA.Lastly,11 characteristic wavelengths were used to build prediction model applied by SVR.The determination coefficient(R2) and the root mean squared error of prediction(RMSEP) for prediction model were 0.973 and 1.501 1 mg/L,respectively.The experimental results showed that the research method in the paper could satisfy the request of determination of aureomycin content in duck egg white.
