摘　　要：在微/纳米尺度下原子力显微镜已成为研究木质材料的重要工具。本文基于原子力显微镜对速生杨木细胞的特征参数进行测量。结果表明:利用原子力显微镜,完全可以在微/纳米尺度下对速生杨木的细胞形态特征进行测量;杨木细胞横截面的导管壁厚平均尺寸为2.230 μ m;木纤维壁厚平均为2.044 μ m,壁长平均为9.498μm;细胞外径平均为19.723 μ m。Atomic Force Microscope（AFM） becomes an important tool for the research of wood material at micro and nano-level scale. On this paper, the characteristic parameters of poplar wood cell were measured based on AFM. The results showed that AFM could be completely used in the measurement of characteristic parameters of poplar wood cell at nano-level scale. On the cross-section of poplar wood cell, the average thickness of vessel wall is 2.230μm, the average thickness of fiber wall is 2.044μm, the average long of cell wall is 9.498μm, the average diameter of cell wall is 19.732μm.
