摘　　要：在人体、动物实验基础上,对有可能作为人体热舒适客观评价指标的重要生理参数进行探讨。人体热反应实验在人工气候室内进行,对不同环境温度下受试者的生理参数和主观感觉同时进行测量。研究结果表明:受自主性体温调节活动影响的生理参数如人体皮肤温度、心率变异性、新陈代谢率、脑电波、肌电、排汗率与人体热舒适具有较好的生理相关性,并且在人体处于热舒适与不舒适状态时差异显著,具备作为人体热舒适客观评价指标的生理基础;平均皮肤温度反映热舒适程度的灵敏性较高,具备较高的可靠性,而且其测量与计算较为简单,可作为一个有效的客观指标来评价稳态热环境下的人体热舒适程度。Based on the human and animal experiments,several potential physiological indices were discussed.The experiments were carried out at different air temperatures,and the physiological response associated with thermoregulation was measured.And subjects＇ thermal comfort and sensation were investigated.The results indicate that skin temperature,heart rate variability,metabolism rate,brain wave,discharge frequency of muscle and sweating rate have favorable physiological relationship with thermal comfort.They can reflect thermal comfort in specific thermal environment.Among these physiological parameters,mean skin temperature has higher sensitivity and reliability,with easy measurement and calculation.Therefore it can be used as an effective objective index to evaluate thermal comfort in steady thermal environment.
