摘要
本文研究将大麻杆除髓，分离出韧皮部和木质部，测定其化学组成，并采用振动球磨的方法分别提出木素，以经典化学法与现代检测仪器相结合，研究其化学特性．结果表明两部分原料不论化学组成还是其木素的结构特性都存在着较大的差别．
The hemp stalk removed it pith is separated into phloem and xylem,and their chemical compositions are tested,and the lignin is extracted by vibro-ball grinding method,its chemical characteristics is studied by both classic chemical methods and modern testers.The results show that are obvious differences between the two parts of the raw material whether the chemical compositions or the characteristics of its lignia structure.
