AbstractIn this paper, we present a self-consistent, unified model for the solar transition region (10(4) < T < 10(6) K). Motivated by Athay's conceptual model that the isothermal surfaces of the solar lower transition region are highly roughened, we construct a configuration of isothermal surfaces for the solar transition region in which the curvature of isothermal surfaces is assumed to decrease from the lower transition region to the upper transition region. The magnetic field is assumed to be vertical, Based on this picture, we demonstrate that the thermal structure of the entire solar transition region can he regarded as being determined by constant energy of combined conduction (parallel and perpendicular to the magnetic fields) transported across isothermal surfaces. After allowing the parameter xi, the ratio of the area of the curved isothermal surface to the area of the parallel plane, to decrease exponentially from approximately 800.0 at the bottom of the solar transition region to 1.0 in the upper transition region, the predicted differential emission measure curve can be in good agreement with the observation in the entire transition region provided that the decreasing coefficient is suitably chosen.
