چکیده انگلیسی
With specific focus on at the progenitor model, Ws15 M⊙, we have carried out numerical simulation of the instantaneous supernova explosion process using the programWLYW89. It is indicated that a proper adjustment of the pressure gradient without altering the pressure during the collapse and rebound phases can lead to successful instant explosion. In the case of limited energy release by gravity, the adjustment of the pressure gradient can strengthen the mechanism of convective transfer of energy, shorten the duration of the explosion and increase the explosion energy, so making a success of strong instantaneous explosion.
