中文摘要：

用宏观—微观模型系统计算了Z=94—112偶偶超重核的基态性质．其中宏观部分基于液滴模型，微观部分采用改进的谐振子势．理论计算的结合能、Ⅸ衰变能与已知的实验数据符合，理论计算结果也与Moller的计算结果符合很好．这肯定了宏观微观模型对超重核性质研究的可靠性和稳定性．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．

英文摘要：

Based on the macroscopic liquid drop model and microscopic model with the modified single-particle oscillator potential, we have systematically calculated the ground state properties of superheavy even-even nuclei with proton number Z = 94-112. The theoretical binding energies and alpha-decay energies are in good agreement with the experimental data. They also agree well with MSller＇s theoretical results. The reliability of macroscopic-microscopic model when it is used in superheavy nuclei is confirmed by our calculation and comparison. The properties of some unknown nuclei are predicted and they will be useful for future experimental research.
