摘　　要：In the paper the authors from the Key Laboratory of Particle Astrophysics,Institute of High Energy Physics,Chinese Academy of Sciences in Beijing proposed a new model trying to explain the knee at cosmic ray spectra.The knee kept as a puzzle in cosmic ray physicsIn the paper the authors from the Key Laboratory of Particle Astrophysics, Institute of High Energy Physics, Chinese Academy of Sciences in Beijing proposed a new model trying to explain the knee at cosmic ray spectra. The knee kept as a puzzle in cosmic ray physics for nearly half a century. The work was inspired by the recent observation of anomalous excess of electrons and positrons in cosmic rays. The work tries to explain the knee and the electron/positron excess in a single model.
