论文摘要
我们简要讨论最近发现，由于在树级和更高的循环顺序上存在外部电磁场，对QED有效作用的可还原贡献。我们将这些贡献对各种现场配置的物理影响分类，并讨论强场渐近极限。
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.
