The relationship between perceived odor intensity and flow rate during inhalation was studied. Thirty subjects, mainly students of psychology, participated. The odor from a solution of pyridine and water (0.5 ml/liter of H2O) was inhaled at five different flow rates, ranging from 75 to 1000 ml/sec. Three different conditions of sniffing were used, i.e., constant-duration sniffing (2 sec), constant-volume sniffing (1000 ml), and three successive short sniffs. The perceived odor intensity, expressed with a magnitude-estimation method, was found to increase with flow rate under all sniffing conditions.
研究了吸入过程中嗅觉强度与流速之间的关系。30名受试者参与其中，主要是心理学专业的学生。以五种不同的流速（范围从75至1000毫升/秒）吸入吡啶和水的溶液（0.5毫升/升H₂O）产生的气味。采用了三种不同的嗅闻条件，即持续时间恒定的嗅闻（2秒）、体积恒定的嗅闻（1000毫升）以及三次连续的短嗅闻。通过量级估计法表示的嗅觉强度在所有嗅闻条件下均随流速增加。
