摘要：
The theoretical approach to describe the delay time of a phase transition in low-temperature phase of relaxors is developed. Localized charges create local electric fields which stimulate occurrence of microclusters with local polarization. In high electric fields conduction electrons activate these local levels via shock ionization. The dependences of the delay times of the phase transition on temperature and the value of the external electric field is obtained.
