摘要：
A theoretical analysis of the nonlinear field dependence of the pulsed radiation-induced conductivity of polystyrene in strong electric fields is performed. An explanation of the previously uncomprehended phenomenon of the sharp increase in the radiation-induced electrical conductivity in the presence of an electric field with a strength of above 5 x 10(7) V/m is proposed. This behavior cannot be explained within the framework of Onsager's theory of the field-assisted thermal production of free charges from generated geminate pairs.
