帮我润色以下段落使其符合科研论文的逻辑注意不要改变意思：根据图22可知NaOH的质量分数对纤维素的得率影响显著p＜005。随着NaOH的质量分数增加水稻秸秆中纤维素的得率呈下降趋势。在反应体系中OH-离子可减弱半纤维素和纤维素之间的氢键以及半纤维素与其他成分之间的酯键冯志强 et al 2022从而使半纤维素中的乙酰基和糖醛酸基团脱离导致木质部分子间共价键断裂、木质素的结构也被破坏包裹在其中的纤维

According to Figure 2.2, it can be observed that the mass fraction of NaOH has a significant impact on the yield of cellulose (p<0.05). As the mass fraction of NaOH increases, the yield of cellulose in rice straw decreases. In the reaction system, OH- ions can weaken the hydrogen bonds between hemicellulose and cellulose, as well as the ester bonds between hemicellulose and other components (Feng et al., 2022), thereby causing acetyl and uronic acid groups in hemicellulose to detach, leading to the rupture of covalent bonds between wood components, and the structure of lignin is also destroyed, resulting in the peeling and swelling activation of cellulose (Zhan et al., 2022). However, when the concentration of NaOH is too high, some of the peeled cellulose will be excessively swollen, becoming fragile and lost, resulting in a decrease in cellulose yield. Therefore, the concentration of NaOH in the reaction system should be controlled within a certain range to ensure that the yield of cellulose is not affected. As shown in Figure 2.2, although the mass fraction of NaOH has a significant impact on the yield of cellulose, there is no inflection point in the yield during the experiment. In addition, when the mass concentration of NaOH is 4 wt%, the yield is the highest, and the amount of alkali solution required is the least, making the experiment economically feasible. Therefore, this study chooses to use a 4 wt% NaOH mass concentration alkali solution for subsequent experimental research.
