Abstract：
At the atmospheric depth x=700 g/cm ², the vertical intensity of the antiproton is calculated by using the data of the high energy accelerators. The comparison with the experimental result shows that up to energy E₀=10 ⁵GeV of the primary cosmic ray, the law of the pN collision producing antiproton is consistent with the law of the pp collision at the energies of the high-energy accelerators.
