Single tracks of unaccompanied charged hadrons, within a horigontal area of 0.23m~2 have been measured with a magnetic spectrometer, a pre-selector of momentum in combination with a multiplate cloud chamber in a laboratory at 3220m above sea level. Taking various possible corrections into account, the negative-positive ratio of charged hadrons was obtained as N~-/N~+=0.53±0.05 in the momentum range of 10-20 GeV/c. If we considered N~+ contained only P and π~+, N~-were π~-and that N_π+/N_π-=1, we deduced the result N_π-/N_p=0.9±0.1. Taking the form of the π~-integral spectrum as j(>p)=Kp~(-γ), it was estimated that γ(?)2.3 in the momentum range 5—20 GeV/c. In this paper the integral verticel flux intensity of all charged hadrons was also estimated roughly, the result is:j_(?)~(ρ+π)(>12 GeV/c)=(7.4±0.7)×10~(-5)/cm~2·sr·s.
