Abstract
The general properties of two-dimensional polarons with non-zero momen tum are investigated by a concise approach. Some characteristic parame ters of polarons, such as the ground-state energy, the phonon number, the effective mass and the distribution of phonons as functions of the total polaron momentum and electron-phonon coupling strength etc., ar e calculated numerically in a wide range of the coupling strengths.
