| 摘 要： | 考虑S矩阵元和物理的截面及寿命之间的普遍关系，采用一种变通方法，通过对中微子动量k和k’的积分计算，由μ衰变寿命的观测值和实验值得到弱衰变耦合常数，最后得到μ衰变的寿命r．

| Abstract: | Considering the general relationships between S matrix elements and physical cross - section life, we got the μ decay of r life through calculating the k neutrino momentum and the k＇ points from the observations and experiments of μ decay life. The whole calculation gave us a more clear and simpler derivation. |
