| 摘 要： | 对量子电动力学中重整休群方程作了新的研究。把所有的荷电轻子和夸克都计入之后，对跑动耦合常数从Ｑ＝０起一直算到Ｑ＝ｍｚ使符合实验数据，这样给出（ｕ，ｄ，ｓ）的平均质量为９２ＭｅＶ。

| Abstract: | A new study of renormalization group equation (RGE) in quantum electrodynam ics (QED) is presented,taking all the charged leptons and quarks into account. The running coupling constant (RCC) from Q= 0 till Q=mz has been calculated to fit the experimental data Wbich leads to an average mass of light quarks mq= 92 MeV, (q=u,d,s). |
