Using the X-ray data from the SMM Satellite and the optical data from the Yunnan Observatory, the Class 3B flare of 1980 July 14 was analyzed. The time variation of the X-ray spectrum was obtained, the total number of electrons at the time of the flare and their mean energy was calculated and measured and the positions of the H-alpha flare and the X-ray burst source was compared. The results show: (1) that the hard X-ray burst was caused by high-energy non-thermal electron beam; (2) that the soft X-ray burst was basically generated by thermal bremsstrahlung of hot plasma, but the contribution by non-thermal electrons must also be included; (3) that the determined height of the X-ray burst source depends on the flare model and the magnetic field configuration of the active region. The results obtained support the newly emergent flux model of flares.
