1·The color screening effects are investigated on heavy quarkonium spectra within the framework of heavy quark potential model.

在重夸克势模型理论框架下，研究了重介子谱的色屏蔽效应。

2·One of the most challenging open problems in heavy quarkonium physics is the double charm production in annihilation at B factories.

B 工厂中通过双的单举和遍举的产生是重夸克偶素物理中的一个具有很大挑战性的课题。

3·The results shown that R (PT) is insensitive to the heavy quarkonium production mechanism and only related to the nuclear effect models.

结果发现，其为一个对色八重态产生机制不敏感，而只与核效应模型有关的量。

4·Using a potential model with relativistic correction we evaluated the spectrum, lepton decay widths and radiative transition widths of heavy quarkonium systems.

本文用考虑了相对论修正的势模型计算重夸克偶素的能谱、轻子宽度和辐射跃迁宽度。

5·A relativistic quark model based on the quasipotential approach in quantum field theory is briefly introduced, and by using this model, heavy quarkonium mass spectra are calculated in detail.

摘要介绍了量子场论中基于准势途径的一个相对论夸克模型，并使用这个相对论夸克模型计算了重夸克偶素的质量谱。
