摘　　要：研究了蒸汽爆碎处理甘蔗叶提取木糖过程中爆碎压力、维压时间对木糖溶出量的影响:木糖溶出量随爆碎压力增加而增加,随维压时间增加,先增大后减小,随粒度增大而减小,随固液比增大先减小后增大。并采用响应面实验和DesignExpert7.0软件分析实验设计拟合得到的模型较好地符合实际,并得到最佳爆碎工艺为:爆碎压力1.1MPa,维压时间12.5min,粒度100目,液料比15∶1(v/w),蒸汽爆碎是一种很好的甘蔗叶提取木糖的预处理方式。The steam explosion affected the production of xylose from sugar cane leaves by vitriol.In this paper,two primary factors： the pressure, the time of keeping pressure were studied. Firstly, when the pressure raised, the content of the xylose increased; when the time of keeping raised, it increased firstly, then reduced;when the granularity got large, it became reduce;when the proportion of the sugar cane leaves to water became increase, it became reduce and then increased.A mode was also got according to the practice well and the best technology with the RSM and the Design Expert7.0 software.It provided the best production technology were：the pressure was 1.1MPa, the time of keeping pressure was 12.5min, the granularity was 100, and the proportion of water to the sugar cane leaves waslS：t （v/w）.It indicated that steam explosion was a good dealing way to the fiber material.
