摘要
热刺激电流技术是研究聚合物驻极体内电荷衰减及贮存的有力工具．用分压技术使补偿运算放大电路能够测量１０－１３Ａ的电流．整套设备能在－１９０～１６０℃按０．５～４℃／ｍｉｎ均匀升温．
Thermo stimulated current (TSC) technique is a valuable tool in studying the charge decay and charge store in polymer electrets. The divide voltage technique is adopted to make compensating operation ample circuit could measure a weak current of 10 -13 A. The whole apparatus is capable of rising temperature at the same speed of 0.5￣4 ℃/min from -190 ℃ to 160 ℃. TSC of polypropylene is measured.
