摘　　要：本文以桉木浆为例,研究了扫描电镜低真空模式在纤维表面形貌分析中的应用,并就扫描电镜加速电压等参数对于成像效果的影响进行了探讨。结果表明,在低真空模式下,未经镀金处理的桉木浆纤维成像效果良好,设置加速电压为15kV,工作距离为5.5-7mm,真空度为10Pa时成像效果最佳。Abstract： The low vacuum scanning electron microscopy technology was applied for eucalyptus pulp fibers surface analysis. The relationship between SEM parameters including electron high tenison and the imaging effect was also investigated. The results showed that the no -coating eucalyptus pulp fibers were successfully imaged in the low vacuum mode. The optimum condition for imaging was set electron high tenison as 15kV, working distance as 5.5 -7ram, variable pressure as 10Pa.
