摘　　要：在前期热化组分模型的讨论中,系统讨论了中心热化区的相关特性,而对两边碎裂区的相关性质还未充分讨论.在前期工作的基础上,进一步讨论了碎裂区的相关特性,初步定量得到了碎裂区变化规律,对TCM模型进一步进行了完善.We have found that the thermalization component model（TCM） can successfully be used to analyze the data of charged hadrion distributions at SPS and RHIC in the central thermalization region in former paper detailedly.By comparing with the fragmentation,the fragmentation region is unclear.In this paper,for further investigating the TCM in that region,we study the particular properties of fragmentation and provide primary and quantitative conclusions.

关 键 词：TCM RHIC能区 碎裂区
