摘　　要：光速是物理学最重要的常量之一。通过分析光电振荡法测光速实验的原理及测量数据,发现了测量仪附加时延造成的系统误差,完成了误差的补偿和修正,使光电振荡法测光速的相对误差从13.6%改善为0.6%。The light speed is one of the most important physical constants. According to the analysis on the principles of the experiment of measurement of light speed with optoelectronic oscillation signal and the measurement data,this paper finds the systematic error caused by the additional time delay of measuring instrument,finishes the compensation and correction of the error,and makes the relative error of the measurement of light speed with optoelectronic oscillation signal be improved from 13.6% to 0.6%.
