✦ Synopsis

This paper studies the temperature and density distributions of the transition zone and inner corona in two cases: (1) the action of mechanical waves (e.g. Alfvrn waves) in a self-consistent theoretical model; (2) the solution of the energy equilibrium equation by assuming that the upper corona is heated by mechanical wave energy; but the lower part is heated by conduction, while cooling is by radiation. We make a comparison between two models corresponding to the above two cases. Calculations show that in our case collisionless Alfv~n waves formed in the bottom of the transition zone can only transfer upward to about one scale height, and the pressure in the transition region decreases with height.
