We study the process of rapid quenching of the liquid iron at 2200K through 2000K, 1800K, 1600K to 1400K and then obtain the statistical analysis of the pair distribution function, mean square displacement, correlation and the Voronoi polyhedra at the temperature equilibrium state.

研究了液态铁在2200K下淬火，经过2000K、1800K、1600K至1400K的过程，并统计分析了各温度平衡态的双体分布函数、均方位移、配位数、及对Voronoi多面体进行分析。
