A model of P-spectrum and some characteristic parameters which gave an overall description of the Profile fractal were proposed and used in the statistical analysis of the Profile and rupture mechanism reserarch of ductile iron fracture. Key words:  fracture profile      fractal      differantial curve      rupture      Received:  18 April 1997      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1997/V33/I4/375 1Banerji K.Metall Trans,1988;19A:961 2穆在勤,李淑清.全国分形理论及其应用学术会议资料.武汉:华中理工大学科学技术协会,199:73 3龙起易,陈军,陈继志.全国分形理论及其应用学术会议资料.武汉:华中理工大学科学技术协会,1991:77 4Wright K,Karlsson B.J Microsc,1983;130:37 5Underwood E E,Banerji K.Mater Sci Eng,1986;80:1 6刘文予,朱耀庭,朱光喜,张军,林汉同。全国分形理论及其应用学术会议资料,武汉:华中理工大学科学技术协会,1991:90 7Voigt R C.Trans Am Foundrymer’s Soc,1986;94:637 8董连科.分形与应用.中国科学院金属研究所内部资料,1990:48 [1] LIANG Kai, YAO Zhihao, XIE Xishan, YAO Kaijun, DONG Jianxin.
