Abstract：
A mass formula with deformation and shell corrections for a few free parameters was described.By means of the formula the calculations of 1440 nuclear masses and 1250 two neutron separation energies s_2n in the region of 28≤Z≤81 were performed.The root-mean-square deviations are respectively 1.01MeV for nuclear masses and 0.57MeV for s_2n.The results of the theory could also reproduce the characters of the closure shell,the subshell and the deformation of the nuclei.
