The electrolytic titration method was more accurately than the inverse titration method for 2%~10% of alkene and the inverse titration method was more accurately for 0.62%~0.040% of alkene and relative error was 2~3% and -4.5~-3.5% respectively.

• 烯烃的质量分数在2%25~10%25之间时，电位滴定法比反滴定法的测量结果更加准确，相对误差约为2%25~3%25；烯烃的质量分数在0.；040%25~0
