结果表明，即使是真空中超强激光场产生的单个e（-）e（+）对，也会引起雪崩式QED级联的发展，从而迅速耗尽入射激光脉冲。这证实了玻尔的旧猜想，即临界QED强度E-S m（2）c（3）/eh的电场永远不会产生。
It is shown that even a single e(-)e(+) pair created by a superstrong laser field in vacuum would cause development of an avalanchelike QED cascade which rapidly depletes the incoming laser pulse. This confirms Bohr's old conjecture that the electric field of the critical QED strength E-S m(2)c(3)/eh could never be created.
