In the present paper, in terms of the theory about the mechanisms of radio radiation, we have briefly classified, induced, summarized and reviewed the methods for deriving the magnetic field in the solar (radio) active regions.

We briefly discuss the observed features including the high flux density, short duration, narrow emission band, fast frequency drift, quasi-periodic oscillation and fast variation of polarized components, of 51 spike emission events observed at 2545/

In the present model, we have assumed the plasma conditions above a solar active region to be varying continuously from the center of the active region to the adjacent quiet region and derived the 3-dimensional distributions of three physical paramet

By using the data of an especially great solar radio microwave burst occurring at 1700 UT on 30 October, 1992 in a “very active” active region NOAA/USAF Region 7321, on the basis of the theoretical emission mechanism of nonthermal gyro-synchrotro

Choosing a representative solar radio microwave burst, a typical burst which contains a precursor and an impulsive burst followed by a slowly decaying component, as an example, we have researched its radio emission mechanism and calculated the two im

Using the theory of radiation mechanism of gyro-synchrotron from both the thermal and the nonthermal electrons and adopting the relation between the peak frequency and the corresponding rise time of microwave bursts, we have derived several varied an

We assume that the physical conditions above an active solar region vary continuously from the centers of sunspots to the adjacent quiet region and try to take into account the influence of the magnetic field. Thus we calculate the three-dimensional

Based on the theory of gyro-synchrotron radiation from both thermal and nonthermal electrons, and adopting the relation between the peak frequency and the corresponding rise time of microwave bursts, we have derived several analytical formulae for ca
