A simple method is presented for diagnosing the electron temperature and density of a rapidly heated, coronal-type plasma from observable, non-equilibrium enhancements of X-ray line emission. This method, it is argued, is applicable to the study of solar flares. Accordingly, theoretically predicted line enhancements are given for a representative selection of X-ray lines prominent in the preflare coronal emission spectrum. Some of these predicted line enhancements should soon be observable with instruments aboard the Solar Maximum Mission.
