摘要
本文讨论了前文提出的ＳＵ（５）大统一模型中费米子与规范场的相互作用．得到的弱电作用与标准模型一致；得到的孤粒子内部的规范作用近似于ＱＣＤ理论．本文证明了实验上只能探测到电荷，而不可能探测到前文提出的内电荷；对分数电荷的根源提出了一种解释．按本模型，三代已知轻子仅仅弱、电作用是相同的，它们与未知规范场的作用并不相同．在对称性破缺前，ｓｉｎθｗ＝１／２．
The interactions of fermions with gauge fields in the SU(5) grand unified model presented in the preceding paper are discussed. The electroweak interactions obtained from the present model are consistent with the standard model, the gauge interactions inside a soliton are approximate to the known QCD. It is proven that only charge Q0 can be detected experimentally, and the interior charge Qi presented in the preceding paper cannot be detected. A possible explanation of the origin of fractional charge is presented. Only electroweak interactions of three generations of leptons are the same. Their interactions with unknown gauge fields are different. Before spontaneous symmetry breaking sinθw= 1/2.
