Abstract：
An analysis on the characteristics of lateral distributions of the shower particles in high energy family events with visible energies 100TeV-400TeV observed in lead emulsion chambers at Mt. Kanbala (5500m a.s.l.)is done. The experimental results are compared with those of the corresponding Monte Carlo simulation. The code CORSIKA with QGSJET as the hadronic interaction model is applied in the simulation.It shows that the lateral distributions of shower particles in the simulated family events are basically in agreement with experimental data and the whole distribution tendency of the rate of energy concentration for simulation is basically consistent with experimental data.
