In our paper we present theoretical assumptions and methodology of our investigations of interactions occurring between non-thermal electrons and plasma in flaring loops as well as the energetic balance of the solar flares. Taking into account an influence of the energy distribution of the non-thermal electrons speeding down the flaring loops, geometry of the loops and properties of the plasma (density, temperature), radiative losses of the material and other processes, we intend to explain the processes of the plasma evaporation and formation of the observed chromospheric emission in strong Fraunhofer lines (like H-alpha, calcium lines etc.).
In our investigation we using two approaches: semi-analytical considerations of the observational data and hydrodynamic modeling of the flaring loops. As an example of the applied methodology, we present preliminary results of an investigation of the energy balance of some solar flares of a moderate C class. Our analysis was based on observations collected with Yohkoh SXT and HXT telescopes. |

In our paper we discuss the methodology and optimal strategy of the diagnostic of the temperature and emission measure based on Hinode XRT data. As an example of the applied methodology we present determination of the temperature using two and three filter ratios. We also tested some methods for determination of the differential emission distribution based on Hinode XRT data. |
