摘要
广泛应用于非相对论量子力学的费曼-海尔曼定理被推广到相对论二体波动方程并由此得到了计算介子质量的理论公式。分析表明本文所考虑的两种波动方程不能很好地描述夸克偶素的短程相互作用。
The Feynman-Hellmann theorem widely used in nonrelativistic quantum mechanics is applied to relativistic two-body wave equations from which we obtain the meson mass formula It is shown that wave equations considered here are unable to describe the short-range interaction of quarkonium reasonably.
