结论摘要：

紧密结合BES的实验结果，采用有关处理强相互作用尤其是非微扰效应的唯象物理模型和有效量子场理论方法，系统深入地分析和研究粲夸克偶素和粲夸克介子衰变，围绕强子物理，尤其是新强子态的研究开展了一系列工作。　研究为理解粲偶素到轻强子的衰变机制，寻找胶球存在的判据提供了有用的动力学信息，对一些新发现的粲介子量子数的确定提供了有用的理论依据。发现电磁衰变对VP过程有重要贡献，它对强衰变振幅的干涉可能是导致所谓"ρπ-puzzle"的主要原因。系统研究D、Ds介子的衰变和稀有衰变近百个衰变道，为实验提供有用的理论依据,利用目前实验上测量的几个比较好的衰变道抽取了重要的CKM矩阵元Vcd 和 Vcs。通过QCD求和规则的计算，发现北京谱仪上观测到的X（1860）态很可能是一个胶球和多夸克态的混杂态。提出的重子偶素模型目前可以很好地理解BELLE实验组在粲能区观测到的一系列奇异强子态，并预言了可能存在的其它态。通过对散射相移的分波分析，研究低能强子谱，尤其是0+态如σ ,κ 的性质。发展了一套很好地建立在色散关系、S 矩阵理论和有效场论基础上的有效的计算方法。
