摘　　要：为探究人体不同体段皮肤对气流的敏感性差异及影响因素,测试了人体前胸、后背上、后背下、大腿前和大腿后5个体段在接受低于皮肤温度5℃、等于皮肤温度和高于皮肤温度5℃的气流刺激时,各体段的局部皮肤温度变化率以及主观气流强度感觉,应用韦伯分数分析各体段对气流的敏感性差异。结果表明:通风温度对人体气流敏感性有显著影响,当通风温度与局部皮肤温度相等时,皮肤气流敏感性最差,说明温度感受器对皮肤气流感知发挥重要作用;后背上部与大腿前部对热气流最敏感,而后背下部与大腿后部对冷气流最敏感,但各部位之间并未发现显著的统计学差异。In order to explore the influencing factors of airflow sensitivity for different human body segments,this study evaluated the local skin temperature change rate of each body segment and the subjective airflow intensity feeling of the front chest,upper back,lower back,front thigh and back thigh under the airflow stimuli at temperatures of 5℃lower than,equal to and 5℃higher than skin temperature,and the Weber fraction was used to analyze the sensitivity difference of each body segment to the airflow.The results show that the stimulating air temperature has a significant effect on the airflow sensitivity of the human body.When the stimulating air temperature is equal to the local skin temperature,the skin airflow sensitivity is the lowest,indicating that the temperature sensor plays an important role in the skin airflow perception.The upper back and the front thigh are most sensitive to the warm airflow,whereas the lower back and the back thigh are most sensitive to the cold airflow,although no significant statistical differences were found between the various body segments.
