摘　　要：The cross sections of fragments （δf） produced in the even 36～52Ca projectile frag- mentation reactions at 80 AMeV are calculated in the framework of the statistical abrasion- ablation model. The distributions of af are investigated. Linear correlations between the peak positions of the distributions and charge numbers of the fragment isotopes are found.The cross sections of fragments （δf） produced in the even 36～52Ca projectile frag- mentation reactions at 80 AMeV are calculated in the framework of the statistical abrasion- ablation model.
