摘要：
In this paper, we present an overview of antiproton fluxes measured in modern spectrometer-type experiments PAMELA (2006-2016) and AMS-02 (2011-present). These experiments provided important data on the fluxes of antiprotons of galactic origin and contributed towards the discovery of secondary antiprotons in the near-Earth space. We discuss the impact of the scientific discovery made in the PAMELA experiment as well as the confirmation of these results in the AMS-02 experiment, which was done with high statistical accuracy and additional extension of measurements into the high energy region. An outline of the existing theoretical models that attempt to describe the newly obtained spectra by introducing additional sources of galactic antiprotons is provided.
