【摘要】 本文进一步讨论了推广的 Debye-Hckel 方程中的函数 F2的性质,指出经 F2调节后的点分怖可以存在着两个值,因而存在着两条直线来拟合这—组点。高值必然对应着 F2趋近于常数,这与既有的实验和理论均不符,由此提供了的选择唯一性的根据。同时考虑到自变量离子强度Ⅰ的区间的影响,作者提出了确定方程线性范围的二元回归的方法和提出了相应的结论。更多还原

【Abstract】 The properties of the function F₂ of the extended Debye-H（?）ckel Equation are further discussed,and it is pointed out that since the data distribution adjusted by the function F₂,the two values of a are existed.Thus there are two straight lines to imitate this group of data points.The higher yalue of a corresponds with that the function F₂ tends to a constant,and this doesn t conform to the experiments or the theories established already.From this,a foundation to select the only value of a is provided.At the same time,the influence of the region of ion strength I is considered,the dual regression analysis is suggested as a method for deter- mining the linear range of the equation,and the corresponding conclusions are al- so put forward.更多还原
