The density spectrum and the energy spectrum have been observed at sea level and at mountain altitude (800 g cm/sup -2/) with an AS tray. The exponent of the density spectrum was --1.53 plus or minus 0.1 at 800 g cm/sup -2/ and -- 1.55 plus or minus 0.1 at sea level. The exponent of the total energy flow spectrum was -- 1.7 plus or minus 0.1 at both altitudes. The exponents of the energy flow spectra with AS coincidence both at sea level and at mountain altitude were found to continuously steepen with increasing energy flow, and the spectrum varied largely depending on the condition of AS coincidence. From these features, it was found that (1) there is a clear change in the character of the core at about 10/sup 5/ in size of EAS, and (2) the change comes from interaction character in the high energy region. The series of observations is continuing by means of a water spectrometer, and preliminary results are presented. (auth)
