过渡元素的自由能-氧化态图

DISCUSSION ABOUT THE FREE ENEYGY ——OXIDATION NUMBER DIAGRAM FOR THE TRANSITION ELEMENTS

本文以过渡元素具有多种氧化态的特征，获得过渡元素自由能－氧化态图．利用过渡元素自由能－氧化态图说明过渡元素的化学性质的变化规律．

Through the characteristics of the transition elements with a number of oxidation state, this paper gains the free energy change oxidation number diagrams. It explains the chemical properties of the transition elements by the free energy change oxidation number diagram.
