摘　　要：依据《三点比较式臭袋法》（GB／T14675-93），对不同浓度的嗅辨样品进行分组嗅辨，考察不同性别、不同年龄对嗅辨样品、嗅辨结果准确性的影响。结果表明，嗅辨员年纪越轻，越不易产生嗅觉适应；男性嗅辨员嗅觉适应的出现也往往早于女性嗅辨员；高浓度的样品嗅辨员比较容易出现嗅觉适应，低浓度的样品嗅觉适应情况均不明显。当嗅辨员在连续较长时间嗅辨或嗅辨较多数量样品后，都会明显出现嗅觉适应的情况。为保证实验数据的准确性，建议嗅辨员的嗅辨时间应控制在1h内，嗅辨样品数不要超过20个。To take a smell at individual samples with various odour concentrations, the effect of panel members grouped in different genders and ages was studied on the accuracy of olfactory discrimination according to the national standard of 《Air quality-Determination of odour Triangle odour bag method》 （GB/T 14675-93）. It has been found that the olfactory tiredness would be prone to appear earlier if someone of the odour panel was elder in age or male in gender, or did the examination of samples with higher odour concentration. Most of the odour panel could be obviously tired of olfaction after they had worked for longer time continuously or on quite a number of samples. Considering the accuracy of monitoring data, anyone of the odour panel had better work for no more than an hour or on no more than 20 samples successively.
