在辐射部分子模型的框架下，对纵向极化光子自旋相关的部分子分布Δfγ（x，Q2）及其结构函数g1γ（x，Q2）进行了次领先阶（NLO）QCD分析.适当选择的分解方案和相关的边界条件的重要问题进行了详细讨论。本文定量地研究了非线性光学（NLO）极化部分子分布Δfγ（x，Q2）的两种不同的可能情形下的典型效应。
A next-to-leading order (NLO) QCD analysis of the spin-dependent parton distributions Δfγ(x,Q2) of the longitudinally polarized photon and of its structure function g1γ(x,Q2) is performed within the framework of the radiative parton model. The important issues of a suitably chosen factorization scheme and related boundary conditions are discussed in detail. The typical effects of the NLO corrections are quantitatively studied for two very different conceivable scenarios for the NLO polarized parton distributions Δfγ(x,Q2).
