运用化学键参数模式识别方法,总结氧化物系热力学性质的半经验规律,提出经验函数L作为氧化物酸碱性的标度。L和复合氧化物生成热、氧化物熔体的混合热、活度系数以及Masson熔渣模型聚合平衡常数K_(1,n)等均有对应关系。举例说明了L函数的应用。
The semiempirical rules of the thermodynamical properties of oxide systems have been proposed by the pattern recognition technique with chemical bond-parameter, and an empirical function L has been suggested as a scale for the acidity or basicity of oxides. It seems to indicate that the correlation between L and such physico-chemical quantities as the heat of formation of complex oxides, the heat of mixing of oxide melts, the activity coefficient and polymerization equilibrium constant K_(1,n) of Masson's model of slags may be presented respectively. The applications of L function are illustrated with some examples.
