摘　　要：用宏观-微观模型系统计算了Z=95—113奇-偶超重核的基态性质．理论计算的结合能、α衰变能与已知的实验数据符合较好,也与相对论平均场的计算结果符合很好,这进一步肯定了宏观-微观模型对超重核研究的可靠性．理论计算表明形变对超重核的性质起重要作用．同时,对一些未知核素基态性质的预言可为将来的实验研究提供理论参考．Using the macroscopic-microscopic model, we systematically calculate the ground state properties of superheavy odd-even nuclei with proton number Z=95-113. The theoretical binding energies and alpha-decay energies are in good agreement with the experimental data and with the results from relativistic mean-field （RMF） model. The reliability of macroscopic-microscopic model which is used in superheavy nuclei is further confirmed by our calculations and comparisons. The calculations show that the deformations play important role for the properties of superheavy nuclei. The predicted properties of some unknown nuclei are useful for future experimental research.
