摘　　要：Quantum chromodynamics (QCD) is believed to be the basic theory of strong interaction. Experimental evidence shows that the fundamental parameters of the QCD Lagrangian, i.e. the quark masses and the strong coupling constant, are manifest in the high energy processes. On the other hand, the constituent quark model has been very successful in understanding the spectra and the static properties of hadrons. A challenging problem arises——how does the constituent quark model connect to the QCD theory? Many theoretical physicists try to solve this problem, because it is very interesting and significant not only for understanding constituent quark model (CQM) itself but also for understanding QCD in the low-energy regime, and so for improving the description of
