Simultaneous observation of families and accompanied air showers is carried out at Mt. Chacaltaya with emulsion chambers and a air shower array. The present analysis is based on the data of experiment from 1969 to 1986. 47 families with ΣΕγ ≥ 10 TeV are coupled to the accompanied air showers of size 105 to 108. There is discrepancy between the experimental data and the simulation calculation, which indicate a need of more rapid energy dissipating process in the atmosphere in high energy region of E0 > 1016 eV.
