把片状石墨看作孔洞与裂纹的传统观点，忽略了对片墨在断裂过程中的行为进行研究，因此，也限制了对铸铁本质认识的深化。
The conventional viewpoint, which takes flake graphite as voids and cracks, neglects the studying of its fracture behavior and thus limits the deepening under-standing of cast iron nature.
实验结果表明，在高频脉冲电流作用下铸铁石墨片细化，石墨片变得卷曲，共晶团尺寸减小。
The results show that high frequency pulse electric current can refine and crinkle graphite flake, decrease the dimension of eutectic cell.
