    • The present invention proposes an odor measuring apparatus capable of determining the similarity of the odor of an unknown sample with high objectivity and performing measurements with sensitivity similar to that of the human nose. According to a mode of the invention, an m-dimensional space is created from detection signals of m pieces of odor sensors, and a standard odor vector S1 representing the result of measurement of a standard odor and another vector Sx representing the result of measurement of an unknown sample are drawn in the space. Then, from the angle &thgr; between the two vectors, a degree of similarity is determined within the range from 0 to 100%, where the degree of similarity is corrected taking account of the difference in sensitivity between the odor sensor and the human nose. The degree of similarity of the unknown odor is calculated for each of plural standard odors measured beforehand, and which standard odor is the closest to the odor of the unknown sample is objectively shown by numeral values.
    • 本发明提出一种气味测定装置,其能够以高客观度确定未知样品的气味的相似性,并进行与人鼻相似的灵敏度测定。 根据本发明的一种模式,由m个气味传感器的检测信号和表示标准气味测量结果的标准气味矢量S1产生m维空间,另一个代表测量结果的矢量Sx 在空间中绘制一个未知的样本。 然后,从两个向量之间的角度θ,在0〜100%的范围内确定相似度,其中考虑到气味传感器和人鼻之间的灵敏度差异来校正相似度。 对于预先测量的多种标准气味中的每一种计算未知气味的相似程度,并且通过数值客观地显示哪个标准气味最接近未知样品的气味。
