文摘Experimental evidence shows that the fundamental objects in the quantum chromodynamics (QCD) are the current quarks which are manifest in the high energy process. On the other hand, the constituent quarks as effective degree of freedom have been very successful in describing the hadron properties. The questions are: how do the constituent quarks relate to the QCD quarks? What are the general properties of the constituent quarks?
