| 摘 要： | The quantum chromodynamics（QCD） coupling αs is the most important parameter for achieving precise QCD predictions. By using the well measured effective coupling αsg1)（Q） defined from the Bjorken sum rules as a basis, we suggest a novel self-consistency way to fix the αs at all scales: The QCD light-front holographic model is adopted for its infrared behavior, and the fixed-order p QCD prediction under the principle of maximum conformality（PMC） is used for its high-energy be...
