Relativistic and mass - polarization effects on the energies are included as the first - order perturbation corrections . the quantum - electrodynamics contributions to the transition energies are estimated by using effective nuclear charge 非相对论能量用rayleigh - ritz变分法确定；相对论和质量极化效应用微扰论计算；量子电动力学修正用有效核电荷方法计算。
