摘要
在组分夸克模型基础上，极化质子、中子结构函数随Ｑ~２演化关系得到了研究．同时理论对总的光吸收截面也给出了相应的预言．计算结果与实验数据相一致．
Based on an improved constituent quark model description, the Q2-evolution of the spin-dependent structure functions for proton and neutron are calculated in the resonance region. Moreover,the total photoabsorption cross sections are also predicted. The results are in agreement wiht the recent E143 data.
