从气味强度和成分的其他相关特性出发，比较了几种预测混合气味强度的数学模型的性能。这些模型包括Berglund的向量模型、Patte和lafford提出的U模型的扩展模型、利用心理物理幂律指数的UPL模型以及一些简化模型。模型测试的数据来自文献和新的实验测量，其中28种气味物质及其168种二元，112种三元和28种重复的四元混合物的蒸汽气味强度与1-丁醇相匹配。U模型对文献数据的处理效果最好，这是用幅度估计方法得到的。用简化的向量模型和U模型对丁醇标度法得到的新数据处理效果最好；他们使用了相互作用项cos的常数值。
Performances were compared of several mathematical models for prediction of the perceived odor intensities of odorant mixtures from the odor intensities and some other related properties of the components. The models included Berglund''s vectorial, an extension of the U model proposed by Patte and Laffort, a UPL model which utilizes exponents of the psychophysical power law, and some simplified models. Data for the model testing were obtained from literature and from new experimental measurements in which the odor intensity of vapours of 28 odorous substances and their 168 binary, 112 ternary, and 28 duplicated quaternary mixtures were matched vs. 1-butanol. The best performance on the literature data, which were obtained by the magnitude estimation methods, was shown by the U model. The best performance on the new data obtained by the butanol scale method was by the simplified vectorial and U models; they used constant values of the interaction term cos .alpha.
