摘要：

We derive an analytic form for the Heisenberg-Euler Lagrangian in the limit where the component of the electric field parallel to the magnetic field is small. We expand these analytic functions to all orders in the field strength (Fmu nuFmu nu) in the limits of weak and strong fields, and use these functions to estimate the pair production rate in arbitrarily strong electric fields and the photon-splitting rate in arbitrarily strong magnetic fields.
