摘要	The family events observed with iron emulsion chambers at Mt. Kanbala are analyzed and compared with the simulations by the COSMOS code and CORSIKA code respectively. A detailed study on the production of super-high energy gamma-hadron families with energy concentration behavior is carried out. The preliminary conclusions are: 1) the energy concentration behavior of super-high energy gamma-hadron families is the external embodiment of high energy central shower clusters contained in the families. 2) the mean lateral spread of these clusters is about 0.37cm. 3) the frequency of this phenomenon appeared under the conditions of R less than or equal to 10mm and chi(10)greater than or equal to 90 % is (20.5 +/- 3.1) %. 4) compared to the COSMOS code based on the phenomenological multicluster model, the simulation by the CORSIKA code that adopts SIBYLL model is closer to the analytical results of experiment.
