Abstract：
With Mountain Emulsion Chamber (MEC) data obtained from Mt. Kanbala, the relation between family flux and the energy spectrum of showers in the family is investigated. A Monte-Carlo generator can reproduce the main features of families. It indicated that no global change appeared in the hadronic interaction at the fragmentation region in the energy region from 10¹⁴ to 10¹⁵ eV.
