采用激光粒度分析法测定无催化剂和添加催化剂纳米纤维素的尺寸分布，并对电子显微镜观察法与激光粒度分析法测定无催化剂纳米纤维素的尺寸分布进行了分析。结果表明添加间硝基苯磺酸钠（SMS）制备纳米纤维素尺寸分布较均一，体积数均尺寸为312．013m，所对应的尺寸分布宽度为10．8nm。电子显微镜观察法与激光粒度分析法的无催化剂纳米纤维素样品尺寸分布测定结果较接近，电子显微镜观察法表征纳米纤维素直径尺寸分布更具优势。

Size distribution of nano - cellulose either without catalyst or adding catalyst was determined respectively by laser particle size analysis method, and the size distribution of nano - cellulose without catalyst tested by electron mi- croscopy observation and laser particle size analysis method was separately analyzed. The results showed that size distribu- tion of nano - cellulose prepared by adding sodium m - nitrobenzene sulfonate （SMS） was uniform, its volume number av- erage size was 312.0 nm, and its size distribution width was 10.8 nm. The testing result of size distribution of nano - cel- lulose without catalyst determined by electron microscopy observation and laser particle size analysis method was closer, furthermore, the electron microscopy observation method was much better for determining diameter size distribution of nano - cellulose.
