Abstract：
Using a large magnetic spectrometer, the vertical differential spectra for pions and protons in the momentum range (5—50)GeV/c at 3220 m above sea level were measured. The spectra of pions and protons can be given by j _π ^－ (P)=9.6×1 0 ^－ ⁴ p ^－ ^2.6 (cm² ﹒ sr ﹒ s ﹒ GeV/c ) ^－ ¹ and j_p(P)=1.26×1 0 ^－ ³ p ^－ ^2.5 (cm² ﹒ sr ﹒ s ﹒ GeV/c ) ^－ ¹ respectively. The flux ratio for pions to protons is 0.62±0.14.
