摘要
珍贵木材表面通常具有独特的特征纹理，是表征材料视觉特性的主要依据，也是体现材料优异装饰性的重要因素。评价珍贵木材装饰效果并无统一标准，通常以人的视觉感受及心理感觉进行非量化评价。本研究采用分形维数对家具用珍贵木材纹理特征进行量化表达，结果表明：珍贵木材表面特征纹理的分形维数在2．7144-2．8014，显示出具有比普通阔叶材树种更丰富的图案纹理立体感和秩序度；印度檀香紫檀的分形维数最高值可达2．9673，表明其具有秩序变异度最复杂的特征纹理；东南亚珍贵木材的分形维数值平均值最大为2．7621，非洲的次之为2．7377，中关和南美洲的最低为2．7273。
The unique surface feature texture of valuable wood is the principal basis of material visual characterization and the important factor reflecting the excellent decorative characteristic. There are no unique standard for the evaluation of valuable wood decorative effect, the non-quantitative evaluation by human visual and psychological feeling was adopted normally. The fraetal dimension was used for the quantification of the texture features of valued furniture wood. The results show that ： the fractal dimension of valued wood surface features texture ranged in 2.714 4-2.801 4, which has richer pattern texture stereo feeling and degree of order than that of ordinary hardwood species ; the fractal dimension of India red sand ers was max up to 2.9673, which has a variation of the most complex features of texture ; the maximum val ue of average fraetal dimension of Southeast Asia precious wood was 2.762 1, that of African followed as 2.737 7, that of Central and South American as 2.727 3.
