Abstract

A liquid membrane oscillator containing nitromethane as membrane material has been investigated. The influence of substances responsible for taste belonging to four classes (sweetness, saltiness, sourness and bitterness) on oscillation patterns of liquid membrane oscillators with cationic surfactant benzyldimethyltetradecylammonium chloride (BDMTAC) was examined. A new approach based on Gábor transformation is proposed for obtaining the power spectra of the observed oscillating signals and for establishing "fingerprints" of the investigated substances. It was shown that two-dimensional form of these power spectra might be used efficiently for this purpose.

摘要

对一种以硝基甲烷为膜材料的液膜振荡器进行了研究。考察了属于四类（甜味、咸味、酸味和苦味）的呈味物质对含有阳离子表面活性剂苄基二甲基十四烷基氯化铵（BDMTAC）的液膜振荡器振荡模式的影响。提出了一种基于加博尔变换的新方法，用于获取观测到的振荡信号的功率谱以及建立被研究物质的“指纹图谱”。结果表明，这些功率谱的二维形式可有效地用于此目的。
