For binary systems the new model is formally identical to the associate solution model if the associates are defind in such a way that they contain one atom of the electronegative element. 对于多元体系,新模型比缔合溶液模型含有较少的成分变量和参数。
Fluorine is the most electronegative metallic element widely distributed in nature, people exposure to fluoride through a variety of sources such as water, soil and air. 氟(fluorine,F)是电负性最强的非金属元素,广泛分布于自然界,人可通过各种来源如水、土壤、空气接触到氟化物。
