Abstract
Based upon recent developments of hydromagnetic turbulence, the interaction of a cosmic-ray particle and a moving interstellar cloud is investigated. It is found that the particle can be accelerated by an inductive mechanism with a comparable efficiency to Fermi's mechanisms of collision. However, the efficiency is the highest when the particle is trapped between two interstellar clouds and is accelerated by the combined action of the two mechanisms in a "push-pull" manner. It is suggested that cosmic radiations are primarily accelerated by such a "push-pull" mechanism in some favorable regions in our galaxy.Keywords
