The Equiratio Mixture Model predicts the responses to a series of equiratio mixtures on the basis of the psychophysical functions for the unmixed components. The model predicts the sweetness of mixtures of sugars and sugar-alcohols successfully, but is unable to predict mixture intensity for substances with different dynamic ranges. In this paper, the equi-intensity concept is introduced in the Equiratio Mixture Model by transforming the physical concentrations expressed in molarity into units that produce approximately equi-intense sensations. An empirical test using aspartame/sucrose mixtures shows that the modified Equiratio Mixture Model yields good predictions of mixture intensities.
等比例混合物模型基于未混合成分的心理物理函数来预测对一系列等比例混合物的反应。该模型成功地预测了糖和糖醇混合物的甜度，但无法预测具有不同动态范围的物质的混合物强度。在本文中，通过将以摩尔浓度表示的物理浓度转换为产生近似等强度感觉的单位，在等比例混合物模型中引入了等强度概念。使用阿斯巴甜/蔗糖混合物进行的实证测试表明，改进后的等比例混合物模型能够很好地预测混合物强度。
