摘　　要：利用相对论平均场方法计算了奇异、粲和底超核的部分性质 ,包括各种不同味的超核的单粒子能量以及其他一些静态性质 ,并对结果进行了比较 .对各种味的重子的势阱深度和耦合常数做了估计 ,得到丰富的结果 .建议寻找质量数大于 10 0的粲超核 .同时探讨了不同重子杂质对原子核芯性质的可能影响 .The results of relativistic mean field (RMF) calculations are presented for some of strange, charmed and bottom hypernuclei and compared to each other. The calculation includes single particle energies and other static properties of hypernuclei with different flavours. The potential well depths and coupling constants of these flavoured baryons are estimated and the results show rich behaviour. A search for charmed hypernucleus with atomic number A≥100 is suggested. Possible influences of different baryons impurities on the core nucleus are also examined.
