对于重介子系统，我们研究了由超弦理论启发的有效膨胀-胶子耦合产生的重夸克势。我们通过对重介子系统的自旋平均能级的研究，重点讨论了这种势的新的约束产生机制。通过对Schrödinger和无自旋Salpeter方程的统一解，我们可以以一种现实的方式检查使用相对论动能的影响。所得结果与其他预测结果一致，相对论方程能更好地解释观测到的能级。
For heavy meson systems, we study the heavy quark potential, which emerges from the effective dilaton-gluon coupling inspired from the superstring theory. We put emphasis on the new confinement generating mechanism of this potential through the investigation of the spin-averaged energy levels of the heavy meson systems. By using a unified approach to the solutions of the Schrödinger and the spinless Salpeter equations, we can examine in a realistic way the effects of using a relativistic kinetic energy. The obtained results agree favourably with other predictions and the relativistic equation can better account for the observed energy levels.
