| Outline of Final Research Achievements |
The purpose of this work is to detect Recombining plasma (RP) from many SNR, using the Suzaku high spectral capability, and address new scenario of SNR evolution. We found RP from 7 SNRs for the first time, and study the evolutional scenario to produce the RP. Furthermore we detect Cr, Mn, Fe and Ni K-shell line from many SNRs and address the explosion mechanisms, origin of the Galactic diffuse X-ray emission and the origin of the Cosmic Rays.
