  3. In quantum chromodynamics ( qcd ), vacuum is not trivial, that is, vacuum carry quantum numbers. such a behavior is embodied by non - perturbative con - densates of quarks and gluons. since hadrons are excitations with respect to the vacuum, hadronic properties are ultimately related to properties of the vacuum. based on the vacuum structure, some hadron properties have been described well. in the low energy region, qcd has two very important proper - ties : chiral symmetry spontaneous breaking and confinement, which are closely related to the vacuum characteristics of qcd. much experiments and theoretical studies have shown that chiral symmetry spontaneous breaking is very important to understand the low - energy feature of the strongly interacting physics, and the quark condensates give an expression to chiral symmetry spontaneous breaking. according to goldstone ' s theorem, the goldstone bosons with zero mass will emerge as the chiral symmetry is spontaneously broken. there are two ways : inear and non - linear methods to carry out this constraint. in our paper, we will use the non - linear method
