通过讨论化学短程有序变化的动力学特性来阐明类金属Ｂ影响居里温度Ｔｃ的原因：Ｂ原子含量的变化影响非晶态Ｆｅ１００－ｘＢｘ合金中异类原子共价键和同类原子金属键的形成；这两种键是化学短程有序变化的驱动力；化学短程有序的变化促使Ｔｃ的变化．
By discussing the kinetic properties of chemical short-range orderly changes, the reason why the metalloid B affects the Curie temperature Tc is explained: the change of the B atom content affects the formation of heterogeneous atom covalent bonds and the same atomic metal bonds in the amorphous Fe100-xBx alloy ; These two keys are the driving force for chemical short-range orderly changes; changes in chemical short-range order to promote changes in Tc.
