摘　　要：采用元素分析仪法测得汽油中C/H比(摩尔数之比)与氧含量相结合的方法建立了汽油中碳,氢含量的分析方法,并用该方法测定汽油标样中的碳,氢含量,与元素分析仪直接测定法进行结果对比,C/H比计算法得出的碳,氢含量回收率均优于直接测定法。该方法准确度和精密度良好,可满足汽油中碳,氢含量准确定量分析需要。A novel method for the determination of carbon content and hydrogen content in gasoline was established using the C/H ratio（the mole ratio） from element analyzer and oxygen content in gasoline.This method was applied to the determination of carbon content and hydrogen content in gasoline standard samples.The recoveries of the method of C/H ratio calculation were proved to be better than the results of element analyzer.This method had good accuracy and precision,which could meet the accurate quantitative analysis needs of the determination of carbon content and hydrogen content in gasoline.
