Extensive air showers with sizes from 8×10 4 to 5×10 6 particles were observed by the scintillator array in Kobe University near sea level. Results obtained in the experiment are as follows: (1) The lateral distribution of EAS is well expressed by the NKG function of single age parameter in the range distance from 1 m to 50 m from the core. (2) The average age parameter of EAS decreases with increasing shower size and approaches a constant value, and the fluctuation of age parameters decreases with increasing shower size monotonously. (3) The absorption length \(\varLambda_{\text{abs}}\) of EAS is almost constant in the observed size range, and it is 117±8 g/cm 2 . (4) The integral size spectrum of EAS in the size range 8×10 4 –5×10 6 can be expressed by a power law of single exponent, i.e. \begin{aligned} I({\geqq}N_{\text{e}}){=}(3.01{\pm}0.34){\times}10^{-6}(N_{\text{e}}/10^{5})^{-1.87{\pm}0.05}/\text{m$^{2}$.s.sr.} \end{aligned}
