论文摘要
我们介绍了在双层近似值中F_L的计算，并证明了从α_s^2-阶从因子1/X的协同效应，以及完全重新定义的高点贡献的完全重新亮相的双对数贡献的陡峭X依赖性可确保小x和intutary x和intutary x^2。
We present calculation of F_L in the double-logarithmic approximation and demonstrate that the synergic effect of the factor 1/x from the α_s^2-order and the steep x-dependence of the totally resummed double logarithmic contributions of higher orders ensures the power-like rise of F_L at small x and arbitrary Q^2.
