提出了一个由库仑能和对称能作用组成的超重核α-衰变能（Q值）关系式。它不仅可以在很大程度上验证实验观测和测量结果，而且可以以较高的精度预测最重SHN的Q值，这对今后的实验有很大的帮助。此外，利用该公式还讨论了超重区壳层闭合和对称能对SHN抗α衰变稳定性的影响。
A formula for the relationship between the α-decay energies (Q values) of superheavy nuclei (SHN) is presented, which is composed of the effects of Coulomb energy and symmetry energy. It can be employed not only to validate the experimental observations and measurements to a large extent, but also to predict the Q values of heaviest SHN with a high accuracy generally which will be very useful for future experiments. Furthermore, the shell closures in superheavy region and the effect of the symmetry energy on the stability of SHN against α decay are discussed with the help of this formula.
