了解太阳大气加热的机制是太阳物理学中的一个基本问题。本文综述了我们在太阳活动区色球层大气加热机制方面的研究进展。我们调查焦耳加热由于耗散的电流垂直于磁场的考林电阻率使用的数据约束分析的基础上观测和列表的理论/半经验太阳大气模型数据。作为目标区域，我们专注于太阳黑子本影光桥，我们发现，这种加热机制起着重要的作用，也是高度动态的。
Understanding the mechanisms underlying the heating of the solar atmosphere is a fundamental problem in solar physics. In this paper, we present an overview of our research on understanding the heating mechanism of the solar active region atmosphere in chromosphere. We investigate Joule heating due to the dissipation of currents perpendicular to the magnetic field by the Cowling resistivity using a data-constrained analysis based on observational and tabulated theoretical/semi-empirical solar atmosphere model data. As target region, we focus on a sunspot umbral light bridge where we find that this heating mechanism plays an important role and is also highly dynamic.
