Abstract

This paper investigates the features of the generation of fast and slow MHD shock waves in the lower layers of the solar corona. An analytical solution is obtained at the shock front for both types of shock waves and it is shown that the primary role in the formation of anomalous heating belongs to weak MHD shock waves, which do not have a lower speed limit for generation in the upper layers of the solar chromosphere.

慢磁激波对太阳色球层上层的异常加热
本文研究了在日冕下层快慢MHD激波的产生特征。对这两种类型的激波在激波前沿得到了解析解,并表明在反常加热的形成中起主要作用的是弱MHD激波,它在太阳色球层上层的产生没有下限。
