摘　　要：文中提出了一种测定灰铸铁含锰量的新方法,并进行了较充分的讨论。在理论分析基础上,对冷却曲线反应锰合量的判据做了选定,建立了锰含量与判据间的数学模型。实践表明,该方法是可行的。Abstract In this paper, a new method to determine the Mn content in grey cast iron has been put forward and proved. On the base of theoretical analysis, the criteria on cooling curves concerned with Mn content bas been selec- ted. Mathematical model describing the relationship betwen the criteria and the Mn content bas been established. Facts have proved that the method is useful.
