| 英文摘要 | The strong coupling alpha(s)(s) is an important free parameter of Quantum Chromodynamics. Based on R values measured at BES, the values of the strong running coupling constant alpha(s)(s) at 2.0-3.7GeV are determined using the ss(alpha(3)(s)) and ss(alpha(4)(s)) order expressions calculated by pQCD, then alpha(s)(s) is deduced to the M-z. scale. The numerical prediction on the improvement of the uncertainty of alpha(s)(s) with the decrease of the experimental error of R value in the future experiment is also given. |
