  1. 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

    大量實驗和理論研究表明,手征對稱自發破缺對于理解低能強相互作用十分重要,而夸克凝聚又是導致手征對稱自發破缺的因素。按goldstone理論,伴隨手征對稱自發破缺應該會有零質量的goldstonebosons產生。而對于這一條件的實現有線性和非線性兩種方法本文將用非線性的方法將手征對稱自發破缺應用於su ( 3 )模型即重子八重態,得出描述其強相互作用的手征對稱自發破缺lagrange密度。
  2. Second, the quark potential has to be at present determined phe - nomenologically due to qcd nonperturbation and the mechanism of quark confinement is still in search

    尹其次,由於夸克勢只能唯象地得到,夸克禁閉機制及其對重介子的影響仍在探索之中
  3. Chiral symmetry spontaneous breaking and confinement are two very important properties of low energy qcd

    手征自發破缺和色禁閉是低能qcd的兩個重要性質。
  4. The main assumption of qcd sum rule is that, at the transition from perturbative to non - perturbative regime, the confinement effect can be described as the power corrections in the ope

    Qcd求和規則從關聯函數出發,假設在從微擾向非微擾區域轉移過程中,禁閉效應可以用ope級數修正表徵。
