应用分形几何理论，研究了不同条件下制备的黑稻壳颗粒的表面结构特征．结果表明：（ｌ）黑稻壳颗粒表面结构具有分形体的特征和规律性；（２）热解处理炉内的压力与环境气氛对颗粒表面结构的不规则性几乎不影响；（３）先粉碎后热解处理所得到的黑稻壳，其颗粒表面结构要复杂些 The fractal geometry theory was used to study the surface structure of black rice hulls prepared under different conditions. The results show that: (1) the surface structure of black rice hull particles has the characteristics and regularity of fractal body; (2) the pressure in the pyrolysis furnace and the ambient atmosphere have little effect on the irregularity of the particle surface structure; (3) After crushing pyrolysis treatment of the resulting black rice hull, the particle surface structure to be more complex
