Since the massive neutron stars (NSs) were detected, NSs have received more extensive attention and research. The discoveries of pulsars PSR J0348-0432 and MSP J0740\(+\)6620 confirm the existence of massive NS and therefore present a strict limit to the equation of state (EoS) of nuclear matter, but the appearance of hyperons will soften the EoS. In order to get a stiff EoS and solve the hyperon puzzle, in this paper we firstly study the effects of the saturation properties of nuclear matter on the mass of NS and then in turn, constrain the saturation properties of nuclear matter by the observed mass of massive NSs with SU(6) symmetry. The study shows that based on the SU(6) symmetry, it is almost impossible to obtain a stiff enough EoS to support the maximum mass of a NS up to 2.0 \(M_{\odot }\) within the range of empirical value of saturation properties of nuclear matter.

自从发现大质量中子星（NSs）以来，NSs受到了更广泛的关注和研究。PSR J0348-0432和MSP J0740 \（+ \） 6620脉冲星的发现证实了大质量NS的存在，因此对核物质的状态方程（EoS）提出了严格的限制，但是超子的出现会软化EoS 。为了获得刚度的EoS并解决超子难题，本文首先研究核物质的饱和特性对NS质量的影响，然后再通过观察到的Ns的质量来约束核物质的饱和特性。具有SU（6）对称性的大型NS。研究表明，基于SU（6）对称性，几乎不可能获得足够刚度的EoS来支持最大质量达2.0 \（M _ {\ odot} \）的NS的最大质量。  在核物质饱和特性的经验值范围内。
