聚氯乙烯缺口冲击断面粗糙度定量分析于杰（贵州工学院材料中心，贵阳，５５０００３）金志浩，周惠久（西安交通大学材料系，西安，７１００４９）关键词分形，冲击强度，温度，聚氯乙烯实际材料的断裂表面是一种近似的或统计意义上的分形模型．分形维数是断面粗糙度的定...
ractal dimension of impact fracture surfaces of PVC at differenttesting temperture were investigated by means of secondary electron line scanning.Experimental results shows that the impact strenth rises linearly with the increaseof fractal dimension.The fractal dimension on crack growth region decreases butthat on final fracture region increases with the testing temperature decreasing.
