In this paper a new analytical method is proposed. Using the kinetic equation and taking into account the energy losses for accelerated particles in solar flare, we obtained the time-dependent particle energy distribution. It was shown that the particle energy distribution in emission region is generally different from that in aeceleration region and the deviation from power law speetriim seems to be evident. The results derived from the kinetic equation can be used to analyse the radiation spectrum of the impulsive...

In this paper we further discuss the reverse shock wave model that was suggested by Mckee in 1974. Mckee's formula about the propagation of the reverse shock wave is improved. Finally, we discuss the influence of the reverse shock wave on the evolution of young supernova remnents. The conclusions are: 1. The temperature of the shocked gas behind the reverse shock wave will be increased progressively. The thermal X-ray luminosity emitted by the gas will be decreased. For example, the relative increment of the...

In this paper we further discuss the reverse shock wave model that was suggested by Mckee in 1974. Mckee's formula about the propagation of the reverse shock wave is improved. Finally, we discuss the influence of the reverse shock wave on the evolution of young supernova remnents. The conclusions are: 1. The temperature of the shocked gas behind the reverse shock wave will be increased progressively. The thermal X-ray luminosity emitted by the gas will be decreased. For example, the relative increment of the temperature is about 1% and relative decrement of the luminosity is about 0.2—0.3% every year for Cas A. 2. The relative decrement of the radio radiation in young supernova remnants will be further decreased under the influence of the reverse shock wave. Shklovsky (1960) has predicted a decrement of luminosity of 1.7% every year for Cas A, but the observational value is about 1%. The difference between the two values can better be explained when the influence of the reverse shock wave on SNR's evolution is taken into account.
