摘　　要：本论文用扫描电镜和多媒体纤维镜观察竹浆磨浆过程中纤维的变化。结果发现:磨浆前期,竹纤维初生壁(P)和次生壁外层(S1)破裂,纤维细胞壁表面发生了较明显的起毛,纤维被大量的切断。磨浆中期,竹浆纤维以分丝帚化为主,轴向排列的微纤维逐渐从次外层(S2)上剥离下来。磨浆后期,竹浆纤维继续分丝帚化,微纤维继续从细胞壁表面剥离,但是剥离难度变大。This paper concerns a morphology study on the behavior of bamboo pulp fibers in the PFI refining process by means of scanning electron microscope and multimedia microscope. The results showed that the changes of fiber morphology were different in the refining process~ In the earlier stage of refining process, the primary wall （P） and the outer of secondary wall（ S1 ） were broken, and the surface of the fiber fibrilated obviously. It can also be seen that the fiber were seriously cut off. In the middle stage of refining process, the fibrillation of fibers were ob- vious, and the mierofibrils which were orienting with the axis were stripped down from the outer secondary wall （s2） ue to ~ In the later stage of refining process, the fibrillation of fibers were not so obvious, and the microfibrils contin- strip down from the surface of cell wall, but the stripping process of microfibrils was hard.
