摘要：

我们简要地讨论了最近发现的可减少的贡献QED有效的行动，由于外部电磁场的存在下，在树水平和更高的回路阶。我们对这些贡献的物理效应进行了分类，并讨论了强场的渐近极限。

英文摘要：

We briefly discuss the recent discovery of reducible contributions to QED effective actions due to the presence of external electromagnetic fields at tree level and higher loop-order. We classify the physical effects of these contributions for various field configurations and discuss the strong field asymptotic limit.
