摘要：

Using the nonperturbative Schwinger-Dyson equation, we show that chiral symmetry is dynamically broken in QED at weak gauge couplings when an external magnetic field is present and that chiral symmetry is restored above a critical temperature which is much smaller than root\eH\, where H is the magnetic-field strength.
