以玉米秸秆为原料，探讨稀硫酸预处理玉米秸秆过程中影响糠醛类抑制物产生的因素，运用偏相关性分析法分析不同预处理条件与还原糖、糠醛的相关性。分析得知，影响预处理液中糠醛类抑制物产生的主要因素是硫酸浓度，二者呈正相关。预处理温度和时间与糠醛浓度显著相关，而固液比对糠醛类抑制物的产生没有显著影响。实验结果表明，当硫酸浓度为1％、预处理温度120℃、时间90 min，固液比1∶10时预处理液中糠醛浓度为0．99 mg／mL，还原糖浓度为27．6 mg／mL。

To explore the factors that affect the generation of furfural inhibitor during the process,corn stover was pretreated using diluted sulfuric acid.The correlation between pretreatment conditions and re-ducing sugar and furfural was analysed by partial correlation.The analysis showed that the main factor af-fecting furfural generation was the concentration of the sulfuric acid.There was a positive correlation be-tween the concentration of furfural and sulfuric acid.Pretreatment temperature and time were associated with the furfural concentration significantly;however the solid liquid ratio was not associated with the generation of furfural.The results showed that the optimal results were achieved by using 1% sulfuric acid to pretreat the corn stover at 120 ℃ for 90 minutes and ratio of solid to liquid 1∶10,as results,the furfural concentration was measured as 0.99 mg/mL with reducing sugar at 27.6 mg/mL.
