The transport model of detrapping carriers of the PTFE electret which shifted towards the back electrode of the sample was investigated by means of the heat pulse technique, and the LIPP method in combination with the TSD experiment.

• 利用热脉冲技术和激光感应压力脉冲法(Laser Induced Pressure Pulse Method；LIPP)组合TSD(Thermally Stimulated Discharge)实验研究了PTFE脱阱电荷在电荷层自身场作用下的输运模型.
