Abstract：
For the nuclear mass even-odd difference ratio P/P′, there is sharp contradictionbetween Danos-Gillet's mass formula and the experiment. A new formula is presentedin this article, which has the different forms of coulomb energy, symmetry energy andpairing energy terms from the convensional ones. Not only it gives right value of P/P′but also the good agreement of β stability position and calculated binding energy withthe experiment are obtained.
