摘要
根据实验所测有关电解质溶液的活度系数,确定其数学模型为γ=e^(a+bm+cm^2+d/m)。利用最小二乘法建立了1∶1型电解质活度系数与浓度之间的函数关系式,从而通过此关系式可对任意浓度下1∶1型电解质的活度系数进行预测,其相对误差不超过2.6％。
On the basis of the measure on the activity coefficients of the electrolytes (1 : 1) related to the concentrations, the mathematic model is found by least square method. From it we can forecaste the activity coefficients on one kind of electrolytes at various concentrations. The relative errors of the results are less than 2. 6%.
