摘要
对玉米应力裂纹进行了分形分析,结果表明,玉米应力裂纹具有近似的自相似性,即分形特征。因此,可以用分形的理论进行研究。利用盒维数的定义测量并计算了各种形态裂纹的分维,局部显微单裂、双裂、龟裂的分维平均值为1.08、1.16、1.26;整个剖面上单裂,双裂和龟裂的平均分维值分别为1.148、1.174、1.201。
he fractal analysis on stress cracks in corn was carried.The irregular and rough profile of stress cracks of corn can be regarded as having self-similarity statistically, and can be studided according to fractal theory.The fractal dimensions of each pattern of stress cracks were measured on the basis of definition of box-dimension.The average of fractal dimension of sectional micro-single cracks,micro-double cracks and micro-checked chacks is 1.08,1.16,1.26 defferently,the average of fractal dimension of single cracks,double cracks and checked cracks on complete section is 1.148,1.174,1.201 defferently.
