摘要
Ⅰ.INTRODUCTION The radiation of the solar local radio sources originates from the combined radiation mechanism of both the bremsstrahlung and the gyro-magnetic radiation.This mechanism can basically explain all the radiative characteristics of the radio sources.In the present paper,we will consider an active region possessing a sufficiently strong magnetic field of a unipolar sunspot,taking account of the gyro-magnetic radiation and the bremsstrahlung of the radio sources themselves.
