| Abstract: | An improved theoretical mode of electrical response of normal mode shock stress compressed ferroelectric ceramics is introduced . The relaxation for the dielectric and conductivity of the ferroelec－ tric material are considered as well as the shock front traveling in the specimen. Calculations show that the mode is accord with experiments. |
