摘　　要：通常情况下该实验用以对电子的荷质比进行测量。笔者发现,如果进行逆向构思,把电子的荷质比作为已知量时,可重新进行理论推导从而得到真空中的光速值。基于该理论基础重新设计塞曼效应试验,就可以得到测量光速的一种新方法。本文主要就采用这一方法测光速时,对影响测量精度的主要因素进行了分析。Under normal circumstances the electronic Zeeman effect experiment for the charge-mass ratio measured. This found that if the reverse idea of the electron charge-mass ratio as a known quantity, it can re-theoretical derivation,and thus obtain the value of the vacuum in the speed of light. Based on the theoretical basis for re-engineering Zeeman effect experiment, we can get a new method for measuring the speed of light. This paper mainly on the speed meter of this approach, the main factors affecting measurement accuracy are analyzed.
