摘要：
I report on the survey of a number of X-ray spectra of cool stars of spectral type G and K. The relation between the X-ray luminosities (L-X) and the stellar radii is illustrated. Two spectra of Capella taken at different times show considerable difference in count rate. These spectra have been investigated. Temperature patterns by means of differential emission measure are given.
