中文摘要：

研究电弱统一标准模型（W-S）里的电磁相互作用，传递相互作用的是γ光子传播子，并对光子传播子里的“树图”以及出现轻子与夸克混合圈中的“链圈图”及其“链图”作了考察与分析，获得光子重整化链图传播子函数“精确”解析计算结果．利用这一结果，又对高能物理中备受关注的一类轻子反应：e^-e^＋→μ^-μ^＋作了有关研究，计算出在光子链图传播下的反应截面，并获得“精确”理论计算结果，同时还与实验结果作了对比分析，发现本文理论计算结果与实验吻合较好，获得了有关“辐射修正”的许多重要分析结果．

英文摘要：

The electromagnetic interaction in electroweak interaction unification standard model（W-S）is studied,where the interaction propagator isγ. Besides, the ＂tree propagator＂, ＂chain-loop propagator＂ and ＂chain propagator＂ which emerged in mixing loops of leptons and quarks are analyzed; then the ＂exact＂ analytical result with renormalized photon chain propagator is obtained, and its e^-e^＋→μ^-μ^＋ cross section with proton chain propagator is calculated and obtained. This paper＇s theoretical results are accord with the experiment relatively good, and many important analytical results about ＂radiation correction＂ are obtained.
