Abstract：High-energy cosmic rays are important probe of particle acceleration, propagation, and interaction in the Milky Way, as well as the turbulent status of the interstellar medium. They can also be used to indirectly detect dark matter particles which are postulated to be able to annihilate or decay into cosmic rays. The Dark Matter Particle Explorer (DAMPE) is a high-energy cosmic ray and gamma-ray detector dedicated to indirect search for dark matter and studies of high-energy astrophysics. After its launch in December, 2015, DAMPE detector has been operated smoothly for more than 3 years in orbit and have recorded more than 6 billion events. The performance of DAMPE detector and progress of physical analysis will be introduced. Some physical implication of DAMPE results will also be discussed.
