高能电子在引发聚合物薄膜的损伤过程中起着重要的作用，导致老化或引发雪崩击穿。为了研究这些高能电子的输运性质，以第一代石蜡为聚乙烯的模型材料，采用界面光电发射技术，将电子注入到石蜡中，并与聚乙烯样品的测量结果进行了比较。从能量分布曲线推导出的光电子的平均自由程被认为是电子倍增所需的顺序，从而表明雪崩击穿发生的可能性。并讨论了高能电子注入烃类的可能能量损失过程。
High energy electrons play an important role in triggering the damage process in polymeric dielectrics, causing ageing or initiating avalanche breakdown. In order to investigate the transport properties of these high energy electrons, first paraffin is used as the model material for polyethylene, and the interfacial photoemission technique, the method to inject electrons into it. The results are compared with those measured using polyethylene sample. The mean free path of the photoelectrons deduced from the energy distribution curves was found to be in the order necessary for electron multiplication, thus indicating the possibility of the occurrence of avalanche breakdown. The possible energy loss process of the high energy electrons injected into hydrocarbons is also discussed.
