Description	Combined theoretical and interpretational approach is proposed for better understanding of the eruptive processes in the solar atmocphere. This project can be considered as a natural continuation of our previous work. The simplified numerical models of these processes were built up, including the optical, radio and X-ray emission diagnostics. Simultaneously, observational techniques in optical and radio bandds were essentially improved in our Institute. Now motivated by new results which were ppresented at SOHO Workshop, 1994, Estes Park, USA, at IAU Colloquium No. 153, 1995, Makuhari, Japan and at YOHKOH Conference, 1996, Bath, England, and which appared in the literature, we suggest to study primary eruptive processes in the solar atmosphere, i,e, the magnetic field reconnection and electric current coalescence during the evolution of active prominesces, solar flares and post-flare loops. We suggest to build up more complex models of these phenomena. (en) Navrhujeme kombinovaný teoretický a interpretační přístup k popisu a objasnění eruptivních procesů ve sluneční atmosféře. Tento projekt může být považován za přirozené pokračování naší práce. Zjednodušené numerické modely byly vybudovány, včetně optické, radiové a rentgenové diagnostiky. Současně byly v našem ústavu podstatně vylepšeny observační techniky v optickém a radiovém pásmu. Nyní motivonáni novými výsledky, které byly prezentovány na konferenci SOHO, 1994, Estes Park, USA, na IAU Colloquium No. 153, 1995, Makuhari, Japonsko a na YOHKOH konferenci, 1996, Bath, Anglie a které se objevily v literatuře, navrhujeme studovat primární eruptivní procesy ve sluneční atmosféře, tj. rekonexi magnetického pole a spojování elektrických proudů během vývoje aktivních protuberancí, slunečních erupcí a poerupčních smyček. Navrhujeme budovat komplexnější modely těchto jevů. Zároveň to znamená studovat doprovodné radiové, optické, ultrafialové a rentgenové záření.
