提出了一种扩展动态记录范围的气味记录方法。该方法利用基于变温预浓缩器的高阶传感所获得的丰富信息，将小比例组分对传感器响应的贡献从主要组分中分离出来。然后，利用Savitzky-Golay滤波器实现了小信号的提取，实现了小比值组分的定性和定量检测，并将提取的信息用于记录过程。结果表明，该方法能够成功地记录到目标气味，包括比例低至1%的组分。这种方法对于扩展动态可记录范围是有用的，特别是在具有高印象贡献的组分对传感器响应具有低贡献的情况下。
The odor recording method for extending dynamic recordable range was proposed. In this method, the enriched information obtained from higher order sensing based on preconcentrator with variable temperature was utilized so that the contribution of component with small ratio to sensor response could be separately extracted from that of the main component. Then, the signal extraction technique for small signal was developed using Savitzky-Golay filter for qualitative and quantitative detection of component with small ratio, and then this extracted information was used in recording process. It wits found that the target odors including component with small ratio down to 1% were successfully recorded using this proposed method. This method is useful to extend the dynamic recordable range especially in the case that the component with high contribution in impression has low contribution to sensor responses.
