摘　　要：在扩展夸克模型下,考虑重子的五夸克qqqq■成分,详细研究了重子β衰变过程的轴矢量耦合常数。结果表明,考虑了qqqq■分量的贡献后,计算结果与实验值符合较好。The values of the axial-vector coupling constant GA/Gv of the baryons are investigated in the framework of an extended quark model which including the qqqqiqi components in the baryon wave functions. The results are weU in agreement with the recent experimental data by taking into account the qqqqiqi components.
