  13. The results show that the chiral symmetry is restored partially when the strange matter density increases and 2 plays a very important role in the strange matter which may approach the constituents of the neutron stars. in additions, we can find that the strange matter density where the - condensate emerges is led to the ratio of the nucleon number to baryon number. and the occurrence of - condensate is only in certain density and gradually increases for higher density, so we guess that - field may be necessary to carefully consider for studying the neutron stars

    ( 3 ) -凝聚出現時所對應的奇異物質密度值與核子在奇異物質中的比例有關。另外,雖然本文對夸克凝聚的討論是在低密度的奇異物質中進行的,但是-凝聚的出現卻需達到一定的密度值並且隨密度的增大而遞增,所以我們推測場可能對于仔細研究中子星是一必要因素。
  14. There has been many papers to discuss the in - medium quark and gluon condensates in nuclear matter which use the models with su ( 2 ) l su ( 2 ) r sym - metry. now, we make use of the chiral model su ( 3 ) l su ( 3 ) n including the baryon octet to discuss the quark condensate < qq > in strange matter, where q is an up or down quark field. on the one hand, from the experimetal data, it is found that < qq > vac = - ( 225 25mev ) 3, on the other hand, with the hellmann - feynman theorem, quark condensate can be evaluated on the hadronic level. in this paper, we will investigate the quark condensate in strange matter with the chiral symmetry su ( 3 ) l x su ( 3 ) rspontaneous breaking lagrangian to obtain the variation of the quark condensate in the strange matter when the baryon number change. it can be applied to understand the neutron stars when the neutron star are considered to be constructed by the strange matter. because nertron stars are homogeneous and at very low temperature, we will use the mean - field approximation and zero temperature throughout this paper

    鑒于已有大量文獻討論了核物質中的夸克凝聚,本文將討論在奇異物質中的夸克凝聚。而在介質中的夸克凝聚的基本公式可由hellmann - feynman理論導出,所以運用手征對稱自發破缺拉氏量以及平均場近似,我們就可以討論在奇異物質中的夸克凝聚,由所計算的結果表明: ( 1 )奇異物質中的夸克凝聚隨奇異物質密度的增大而單調減小。 ( 2 ) -凝聚的出現對衰減率有影響。
