We have developed odor sensing systems using the four and six quartz-resonators coated with absorption films, Recognition of citrus fruits with these systems was tried, From the response pattern of resonant frequency, fine difference among thirteen kinds of citrus fruits (Yuzu, lyokan, Tosa-buntan, lemon, grapefruits, etc.) could be discriminated. By vaporizing the order samples, it was able to discriminate with high sensitivity for a short measurement time. The optimization of the sensor-array components has been made, and for the recognition of citrus fruits, 11 kinds of membrane were tried, It is important to analyze the response pattern of quartz-resonators for the optimized odor sensing system. The pattern recognition analysis by neural network analysis was carried out using the gradient of six transient response curves, The recognition probability of this method for eight kinds of citrus fruits is more than 80%.

我们开发了使用涂有吸收膜的四个和六个石英谐振器的气味传感系统，尝试用这些系统识别柑橘类水果，从谐振频率的响应模式来看，十三种柑橘类水果（柚子、lyokan、土佐文旦、柠檬、柚子等）可能会受到歧视。通过使顺序样品气化，能够在短时间内以高灵敏度进行判别。对传感器阵列组件进行了优化，并针对柑橘类水果的识别，尝试了11种膜，分析石英谐振器的响应模式对于优化气味传感系统具有重要意义。利用6条瞬态响应曲线的梯度进行神经网络分析的模式识别分析，该方法对8种柑橘类水果的识别概率均在80%以上。
