Results of Monte-Carlo simulations for combined experiment of emulsion chamber and extensive air-shower array are shown. Two totally distinct models are assumed for nuclear interactions, one based on UA5 Monte-Carlo algorithm (model-A) and the other including exotic processes of Centauro and Mini-Centauro (model-B). Effects of different assumption on chemical composition of primary particles are also considered. Longitudinal and also lateral structures of gamma-families triggered by air-shower size, [ital N][sub e], are studied and are compared with the data of HADRON'' experiment at Tien-Shan. The experimental data are found to disagree with the results of model-A, even when we introduce heavy dominant assumption for primary cosmic-rays. On the other hand, the model-B explains general tendency of the experimental characteristics. It suggests that energy dissipation of produced particles in nuclear interaction is very strong in primary energy over 10[sup 16] eV.
