摘要:

Experiment shows that the impulse electric strength of prestressed polythene film varies appreciably, whereas without prestress it remains constant during a period following quenching from about 100°C. The phenomenon is attributed to morphological changes which influence the density of traps and hence the space charge formed by the prestress.
