摘  要:
根据非线性方程最小二乘法原理、为葡萄酒中酒石酸稳定性的估算进行方程拟合。当X为乙醇含量(%v/v),y为pH值,对酒石酸氢根比率Z计算的方程可被表达为:Z=-P(x)y2+Q(x)y-R(x)。酒石酸稳定性估算的方程为:CP=[K+][Tartrate]Z/100。本文对该方程二维、三维图形特征,方程在生产实际中的应用及低温下判别值的增补问题,进行了重点的讨论。

摘  要:
Curve equation fit for prediction of tartrate stability was completed on the principle of least-square.Theequation Z for (%HT-) is in the form of Z=-P(x)y2+Q(x)y-R(x),where x as concentration of ethanol y as pHof wine. Concentration product for [K+]and [HT-] is in the form of CP=Z[K+][Tartrate]/100.The supplementary workon the reftrence data for stability judgment the characteristics of three dimension figure and the application of theequation to the wine production were also presented.
