我们分析了最近的实验结果增加的快速电子穿透冲击压缩塑料[物理。81，1003（1998）]。这是由阻止功率和电场效应，这似乎是重要的，即使在低至10（16）W cm-2的激光强度的组合来解释。一个重要的结论是，必须考虑快速电子感应加热，改变材料的性质，快速电子传播。在绝缘体中，这导致从绝缘体到导体的快速相变。
We analyze recent experimental results on the increase of fast electron penetration in shock compressed plastic [Phys. Rev. Lett. 81, 1003 (1998)]. It is explained by a combination of stopping power and electric field effects, which appear to be important even at laser intensities as low as 10(16) W cm-2. An important conclusion is that fast electron induced heating must be taken into account, changing the properties of the material in which the fast electrons propagate. In insulators this leads to a rapid insulator to conductor phase transition.
