摘要： 人们普遍接受的硅铁浓度不均匀孕育理论认为[1]硅铁孕育作用是通过形成局部富硅区和形成以CaS等硫化物为核心,SiO2为外壳的晶核联合作用来实现的.

Abstract: In this paper,the thermodynamic theory of nucleation in a cone hole is analysed.On the basis of the calculation of the thermodynamic theory, a crackle inoculation mechanism of cast iron is Put forward. This inoculation mechanism can be used to explain the various phenomona of many experiments.

Key words: nucleation, thermodynamics, inoculation mechanism
