摘要： The electron capture timescale may be shorter than hydrodynamic timescale in inner iron core of core-collapse supernova according to a recent new idea. Based on the new idea, this paper carries out a numerical simulation on supernova explosion for the progenitor model Ws15M$_{\odot}$. The numerical result shows that the size of proto-neutron star has a significant change (decrease about 20{\%}), which may affects the propagation of the shock wave and the final explosion energy.
