G. Abstract Models of the chromosphere-corona transition region in which energy is supplied by thermal conduction and downflow of hot material and lost by radiation are investigated for different magnetic field geometries and for different dependences of downflow velocity on the local temperature. It is shown that neither the field geometry nor the dependence of velocity on temperature are important factors in the comparison of empirical and theoretical emission measures. Each of the models works well for T higher than 250,000 K but fails badly for temperatures lower than that.
