摘　　要：著名的日本 美国乳胶合作实验组的宇宙射线数据被用来展示,如何直接从实验数据出发,获得关于强子化的有用信息.结果显示,在强子化的过程中,自组织临界现象也被观察到了.这个事实预示着,强子化过程中潜在的动力学机制就是复杂系统中的BTWThe question whether, if yes, how useful information on hadronization can be directly extracted from experimental data is discussed, and the well-known cosmic ray data of JACEE-Collaboration are used to demonstrate how the proposed method works. It is observed that Self-Organized Criticality (SOC) manifests itself also in hadronization processes. The obtained result strongly suggests that the underlying dynamics of hadronization is the BTW-avalanche Dynamics for Complex Systems.
