Several problems related to the calculation of an emission measure differential in temperature are resolved using a new calculation technique. The analysis of a flare on 20 April, 1976, is used to evaluate the usefulness of this new approach and to estimate its future value.

The soft X-ray emission of the solar corona is investigated by comparison of the signals of several broad band photometers carried on the Solrad 9 satellite, and sensitive to the region 0.5-20 A. Temperature from 1.5 โข 106 to 25 โข 106 K have been measured with 'emission measure' S N~2 dVranging betw
The time histories of the emission at 10, 30, and 100 keV averaged over the loop from small and large loop thermal models of hard X-ray emission are studied. The small (15 000 km) loop cases show a characteristic delay in the peak of the 100 keV emission relative to the 30 keV emission of about 1.5
The problem of producing the hard X-ray burst at the onset of solar flares may be thought of in terms of the problem of producing the non-thermal electrons which emit the X-rays via bremsstrahlung. Electron acceleration to relativistic energies without similar ion acceleration is difficult to achiev
