| 摘 要： | 为了避免矩方法求解强子结构函数时对函数待定形式的依赖并提高解的精确度,本文采用把A-P方程离散为常微分方程组,用龙格-库塔方法求解的方法,得出随Q2变化的价夸克、海夸克和胶子的结构函数。

| Abstract: | To avoid the dependence of hadron structure functions upon supposed function forms and to improve the accuracy, a new method to find the hadron structure fundtion at high Q2 is discussed in this paper to replace the commonly used moment method. The sturcture functions for gluon and valence quark and sea at high Q2 are obtained by discretizing the A-P evolution equations into ordinary simultaneous differential eqs. and then solving them with Runge-Kutta method. |
