A simple circular odor chart is proposed for the explanation of the relationship between sensory responses (to odor quality and intensity) to odors and chemical analysis data of the odorants responsible for each odor discharged from thirteen odor sources. The odorants were classified into eight odorant groups and were analyzed by a systematic gas chromatographic (GC) technique. The characterization of the trace amounts of the odorants was carried out by using the values of a new proposed unit (pOU) based on the ratio of detected concentration to recognition threshold value. The calculated pOU values of the eight groups were plotted in circular charts. It was found that the shape and size of each circular odor chart represent the quality and the intensity of each odor.
为解释对气味的感官反应（针对气味质量和强度）与来自13个气味源所排放的每种气味的气味物质化学分析数据之间的关系，提出了一种简单的圆形气味图表。这些气味物质被分为八个气味物质组，并通过系统气相色谱（GC）技术进行分析。基于检测浓度与识别阈值的比率，使用新提出的单位（pOU）的值对痕量气味物质进行表征。将八个组计算出的pOU值绘制在圆形图表中。结果发现，每个圆形气味图表的形状和大小代表了每种气味的质量和强度。
