The perceived intensity and quality of binary mixtures consisting of the common but dissimilar odorants, benzaldehyde (almond), eugenol (cloves), propionic acid (vinegar) and (-)-carvone (spearmint), were determined over a wide range of environmentally relevant concentrations. Consistent data were obtained from each of the odor pairs. This showed that the intensity of odorants not their quality determined the contribution of each to the quality of a mixture. Except for the pair carvone-propionic acid, both odorants were perceived only when the difference between their intensities was small. The results confirmed an earlier finding that the total intensity of a mixture is less than the sum of the intensities of the two components, and also showed that it is never less than the intensity of the weaker component. Seven major characteristics of binary odor mixtures are defined.
我们测定了由常见但不同的气味物质组成的二元混合物的感知强度和质量，这些气味物质包括苯甲醛（杏仁味）、丁香酚（丁香味）、丙酸（醋味）和（-）-香芹酮（留兰香味），测定范围涵盖了广泛的与环境相关的浓度。从每对气味物质中都获得了一致的数据。这表明，决定每种气味物质对混合物质量贡献的是其强度而非质量。除了香芹酮 - 丙酸这一对，只有当两种气味物质的强度差异较小时，它们才会同时被感知到。结果证实了之前的一项发现，即混合物的总强度小于两种成分强度之和，同时也表明其总强度从不小于较弱成分的强度。本文定义了二元气味混合物的七个主要特征。
