中文摘要：

从理想的色味连锁相出发,在SU（3）味极限附近,给出了一个3味夸克超导体的近似描述.在手征对称性明显破缺的物理影响下,运用Nambu-Jona-Lasinio（NJL）模型在平均场层次上研究了两种双夸克态和束缚双夸克态的形成.当夸克之间的相互作用非常强时,首次指出了在3色和3味夸克参与Bardeen-Cooper-Schrieffer配对的环境下,轻味双夸克态发生玻色-爱因斯坦凝聚的可能性.

英文摘要：

Starting from the ideal color-flavor locked phase,an approximate description for three-flavor quark superconductor is proposed near the SU（3） flavor limit.Under the physical influence from explicitly chiral-symmetry-breaking,we investigate the behaviors for two species of diquark states and the formations of bound diquark states at the mean-field level.In strongly coupling density regime,a theoretical possibility is pointed out at the first time,that Bose-Einstein condensation of light-flavor diquark states occur in the environment where all three-flavor and three-color quarks participate the Bardeen-Cooper-Schrieffer pairing.
