中文摘要：

利用连续介质模型并基于Nilsson模型考虑微观修正，研究了重核区原子核（Z≥82）基态性质，得到了较好的结果。通过拟合Z≥82原子核的结合能实验数据，得到了两组连续介质模型的新参数。利用这两组参数计算的重核结合能与实验值的均方根偏差约为0．8MeV，电荷半径的均方根偏差约为0．07fm。

英文摘要：

The continuous medium model with shell correction from Nilsson model is used to study the ground state properties of heavy nuclei （Z≥82）. New parameters are obtained for the continuous medium model by fitting the experimental binding energies. The theoretical calculations for the masses and radii are in good agreements with experimental values, and the root-mean-square deviations are about 0. 8 MeV for the masses, and about 0. 07 fm for the radii.
