中文摘要：

采用分形方法对20种典型的木材径向、弦向纹理图像进行了分析，结果表明：木材纹理的分形雏数值能够很好地表征木材表面纹理的形状、分布密度、均匀程度和宽度特征，符合了木材表面纹理的粗糙性和复杂性规律。分形雏数值本身是几个常规纹理特征的综合体，使得纹理特征的表迭得以简化。分形方法为木材表面纹理的分布密度和复杂度等特征参数的定量化分析提供了一种新的思路和方法。

英文摘要：

The images of radial and tangential texture for 20 typical species of wood were analysed by the fraetal method. Results show that fractal dimension is highly correlated with figure, density, uniformity, and width of wood texture, which accords with the regulation of roughness and complexity. Fractal dimension is an equation of some common texture characters, and it makes the expression become easy. The fraetal analytical method provides a new way to quantitatively analyze the character parameters for wood texture, such as density, uniformity, complexity, and so on.
