Scientific paper

The evolution of the temperature and ionization fraction of the expanding envelope of SN1978A are discussed by use of the recombination theory of hydrogen. A new approach to the evolutions of temperature and ionization fraction is proposed based on the fact that the evolutional information of these two parameters must be contained in line variation because the changes in them govern the line variation behavior. By comparing the theoretical Hα light curve deduced from the radiative transfer theory using the escaping probability approximation with the obserational, the evolutions of them are achieved.
