给出了绝热材料中热辐射电子俘获引起的空间电荷效应的详细模型。已获得特定绝缘材料（聚对苯二甲酸乙二醇酯）的解析解。当陷阱位置的能量均匀分布在电荷传输发生的能级以下时，电荷积累和释放的速率主要取决于材料弛豫时间常数ρe与电子从陷阱释放速率的比值。在聚对苯二甲酸乙二醇酯的情况下，当时间常数的这个比率近似为1时，理论和实验之间的一致性相当好。
A detailed model of space‐charge effects resulting from trapping of thermalized irradiation electrons in insulating materials is presented. Analytical solutions for a particular insulating material (polyethylene terephthalate) have been obtained. When the trapping sites are uniformly distributed in energy below the energy level where charge transport occurs, the rate of charge buildup and release depends primarily on a ratio of the material relaxation time constant ρe to a release rate of electrons from traps. Agreement between theory and experiment is reasonably good in the case of polyethylene terephthalate when this ratio of time constants is approximately unity.
