摘要
量子电磁场处在真空态时,它的场量仍然有"真空涨落".本文以简明的办法解释了这种涨落的起因,计算了它对氢原子光谱的影响———Lamb移动.
When the quantum electromagnetic field be in its vacuum state, still its field quantities have the 'vacuum fluctuation'. With a concise way this paper demonstrates the origin of this quantum fluctuation and calculates its effect on 2(()~2S_(1/2)) and 2(()~2P_(1/2)) energy levels of hydrogen atom--Lamb shift.
