摘要
玉米应力裂纹具有近似的自相似性，可用分形理论进行研究。利用盒维数的定义测量并计算了整个剖面上单裂、双裂和龟裂的平均分维值。提出了当量分维概念，计算并分析了不同干燥条件下得到的玉米样品的当量维数。
The fractal analysis on stress cracks in corn is carried out on the basis of definition of box-dimension. The average of fractal dimension of single crack, double cracks and checked cracks on complete sections are measured. The concept and counting methods of equivalent fractal dimension are proposed to measure and analyze the equivalent fractal dimension of stress cracks of corn dried in heated air.
