摘要
A non-topological soliton model with strange quarks is suggested to investigate the phase structure of strange matter.The results are qualitatively in agreement with that obtained by MIT bag model provided the ratio of coupling constants of different quarks to soliton scalar field x_(σ)≡g_(gσ)/g_(qσ) larger than a critical value χ_(c)~0.86,but as χ_(σ) gets smaller than xc,the phase structure may change.
