摘　　要：纸浆细小纤维是造纸纤维原料的重要组成部分,因制浆原料、制浆工艺、打浆工艺等条件的不同,纸浆细小纤维在形态、数量、表面电荷等方面各不相同。纸浆细小纤维的制备可以先对纸浆适当预处理,然后采用筛分仪筛分法、DD J筛分法、湿筛分法等方法进行。纸浆细小纤维可以采用数量分析法、光学长度纤维分析仪法、图象分析法、水力比容积法、共焦激光扫描显微镜法、电镜扫描法等多种方法进行研究。Fines of pulp, as one of the important composition of cellulose material for the paper industry, have different characteristics in shape, quantity and surface charge when pulping raw material, pulping process and beating process differ. After proper pretreatment, fines of pulp can be prepared by the way of Bauer - McNett classifier method, DDJ sieving method and wet -sieving method. Methods used in the research of pulp fines are also introduced in this paper, including quantity analyzing method, optical fibre length analyzer method, image method, hydrodynamic specific volume method, confocal laser scanning microscope method, scanning electron microscopy method and so on.
