Abstract：
The action among nucleons is simplified as the bond of nuclear force from which the formula of volume energy and the formula of surface energy are inferred. And the two parameters are worked out by the binding energy of 21H, and then two parameters are reduced. The formula of binding energy is given by using both the experimental data and the theory value, which is obtained from the semi-rational formula and Zeng′s formula of binding energy. Then basing on this formula of binding energy, we get the D-value of odd-even mass of nuclei and β stable line. In correspondence with the empirical formula of β stable line, the value of parameter is modified, so the final formula of binding energy is obtained. The calculation values of new formula are good agreement with experimental data, especially for heavy nuclei, further supporting the utility of the formula to describe nuclear structure.
