摘　　要：该文建立了北京地区日总辐射的组合模型 :确定性模型 +随机模型。首先采用傅立叶分析得到了日辐射的确定性部分。然后从原始数据减去确定性部分得到随机项。对随机项进行了平稳正态变换 ,并建立随机自回归AR(1)模型。该模型抓住了日总辐射的变化分布特征 ,能够产生具有代表意义的数据 。Combination model of daily global radiation of Beijing is established. The determined or random component of daily global radiation is obtained by Fourier analysis at first, and then stochastic component is formed by subtracting the periodic component from original data. After transforming the stochastic component to a stationary and Gaussian process, AR(1) model is built. The present model captures the main characteristics of the original data, and may produce representative data for energy analysis.
