本文介绍了高电场的影响下，阐明聚乙烯的行为进行的实验结果。特别是当使用原始样品时，会出现一些“异常”，这是聚合物缓慢过渡到预加载状态的结果。它表明，如果两组陷阱被假定，不仅热力学平衡占领，但也必须考虑到的动态捕获和逃逸过程的深的和实验发现的异常的影响下，在该地区的高电场强度超过30 kV mm-1可以解释。数值模拟程序导致定性正确的结果。
The paper presents results of experiments undertaken to elucidate the behaviour of polyethylene under the influence of high electric fields. Especially when using virgin samples, some 'anomalies' occur that are a result of a slow transition of the polymer to a preloaded state. It is shown that if two sets of traps are assumed, not only the thermodynamic equilibrium occupation but also the dynamic capture and escape processes must be taken into consideration for the deep ones and anomalies found experimentally under the influence of high electric field strengths in the region of more than 30 kV mm-1 can be explained. A numerical simulation program leads to qualitatively correct results.
