摘要
基于分形理论建立了可锻铸铁石墨颗粒的生长模型，推导出了分形生长方程：ＲＧ＝Ｋｔ￣（３／Ｄ），该方程揭示了石墨颗粒生长与形态之间的关系，它表明随着分维值的增大，石墨颗粒的生长速度下降，从而解释了石墨颗粒生长过程中其生长速度变化的原因。
Based on the fractal theory,a growth model for graphite nodules in malleable iron hasbeen developed.The fractal growth equation derived is RG = Kt(3/D), which reveals the rela-tionship between the growing process and the shape of the graphite nodules and shows thatthe growth rate decreases while the fractal dimension D increases. This is the reason why thegrowth rate varies during the growth of the graphite nodules.
