On the question of the reaction of a nonlinear system to an impulse action
The author studies the resonance oscillation of crystals in polycrystal ferroelectrics with regard to exterior impulse actions and nonlinear functions of the deformation and the dipole moment. The so-called echo-effect is examined. The main result is a comparison of the manifestations of the echo-effect for different cases of certain nonlinear functions \(\varphi(x)\), where \(\varphi(x)\) are functions of the deformation and the dipole moment.
