论文摘要
我们使用近似于小X处的DGLAP方程，将近代领先顺序（NLO）和近距离领先顺序（NNLO）效应纳入单元结构函数f_2^s（x，t）的模型f_2^s（x，t）和gluon分布g（x，t）中。分析解决方案均在临近领先顺序（NLO）以及近代到领先顺序（NNLO）处。然后，我们与确切的结果进行比较。
We incorporate the next-to-leading order (NLO) and the next-to-next-to-leading order (NNLO) effects in the models of the Singlet Structure function F_2^S(x,t) and the gluon distribution G(x,t) using DGLAP equations approximated at small x. Analytical solutions both at the next-to leading order (NLO) as well as the next-to-next-to leading order (NNLO) are obtained. We then make comparisons with exact results.
