摘要：

Transient response curves for aromas from ethanol solutions or several kinds of alcohols with different ethanol concentrations are observed using CH3Si(OCH3)(3) a sol-gel-film-coated quartz crystal resonator gas sensor. The pattern recognition analysis using principal component analysis or neural network analysis is carried out using three parameters which characterize the transient response curves. The recognition probability of neural network for five kinds of alcohols such as Japanese Sake (ethanol concentration 15%), Shoutyuu (25%), cognac (45%), vodka (50%) and vodka (95%) is 100% for 50 trials.
