给出在质量2Gev附近除粲粒子外还可能存在一批普通介子的色激发态，讨论了这些粒子的性质和它们在实验中表现的行为，并指出它们在一些新现象中可能的贡献。

We suggest the possible existence of several colour excited states with masses around 2 GeV in companion with charm mesons . We also discuss the properties and the experimental behavior of these colour excited states , especially , the possible contribution of these states in several new phenomena .

研究含有粲夸克的粲粒子的产生和衰变性质对检验标准模型，特别是微扰和非微扰量子色动力学具有十分重要的意义。

Studying the production and decay natures of charm-particle , which contains charm quark , this is of great significance for testing the standard model , especially the perturbative and non-perturbative quantum chromodynamics ( QCD ) .
