衣服の着用快適感評価装置の開発

我们研制了一种带显微镜观察出汗的新型出汗胶囊，用于测量热非稳态下的出汗及其频率。在50ml/min的干氮气中，湿度传感器的时间常数为0.91*0.06秒，传感器在皮肤表面出汗后开始工作的时间延迟为0.73*0.04秒。由于湿度传感器可以检测到几秒内的周期性湿度变化，因此这种新型出汗胶囊适合于测量热非稳态下的局部出汗率。所有实验均在气候室中进行，受试者为健康的男性和女性。工作温度保持在32ﾟC，从地板到天花板的风速控制在0.1m/秒。实验开始几分钟后，环境蒸汽压从18毫米汞柱变为25毫米汞柱。在保持状态的15分钟内，压力再次降至18毫米汞柱。一次治疗的总时间为65分钟。视频ca…More Mera用显微镜显示，一些汗滴在几秒钟内周期性地变化，变得越来越大，而另一些则保持不变。利用快速傅立叶变换对局部出汗率数据进行分析，得到了典型的功率谱分布。功率谱在低频区呈1/f型，在高频区呈1/f^2型。利用新的出汗胶囊测量的局部出汗率数据，通过快速傅立叶变换分析，很有可能对出汗类型进行分类。另一项研究旨在通过非接触式测量虹膜温度来获得一些关于核心温度的信息。虹膜温度可能会显示核心温度，因为来自颈内动脉的血液通过虹膜。在三种不同的实验条件下，用辐射温度计测量男女受试者的皮肤温度，用热敏电阻测量鼓室温度和直肠温度，用铜-康铜热电偶测量局部皮肤温度。在体内用冰水或热水引起的热稳态和非稳态状态下，建立了虹膜温度与环境温度、鼓室温度、直肠温度、平均皮肤温度和前额温度之间的多元回归方程。在稳态和非稳态下，虹膜温度可以作为核心温度的指示。在稳态下，鼓室温度将是虹膜和平均皮肤温度的函数。在非稳态状态下，鼓室温度的最大偏差是虹膜温度和直肠温度最大偏差的函数。较少

We developed a new type of sweating capsule with a microscope for observation of sweating to measure the sudorific ejection and its frequency under thermally unsteady state. Time constant of humidity sensor and the time lag that the sensor started to work after sweat on the skin surface were 0.91*0.06 sec and 0.73*0.04 sec, respectively under 50 ml/min of dry N_2 gas. Since the humidity sensor could detect periodic humidity change with a few seconds' cycles, the new sweating capsule was suitable for measuring local sweat rate under thermally unsteady state. All experiments performed in a climatic chamber using healthy male and female subjects. Operative temperature maintained at 32ﾟC and air velocity controlled to 0.1 m/sec from the floor toward the ceiling. Ambient vapor pressure changed from 18 mmHg to 25 mmHg after minutes after starting the experiments. In 15 minutes keeping the condition, the pressure lowered again to 18 mmHg. Whole time of one session was 65 minutes. The video ca … More mera with a microscope showed some sweat drops changing periodically bigger and smaller in a few seconds and others remaining unchanged on the skin. Analysis of local sweat rate data using Fast Fourier Transform gave a typical distribution of power spectrum. The 1/f type of power spectrum showed in the low frequency region, and 1/f^2 types presented in the high frequency region. It is highly possible that sweating types can be classified by Fast Fourier Transform analysis with the data of local sweat rate measured by the new sweating capsule.Another study aimed to have some information on core temperature from a non contact measurement of the iris temperature. The iris temperature might show an indication of the core temperature, because the blood from the internal carotid arteries passes through the iris. Under three different experimental conditions, we evaluated the ires temperature of male and female subjects by means of a radiation thermometer, and tympanic and rectal temperatures with thermistors, and local skin temperatures with copper-constantan thermocouples. Under thermally steady state and unsteady state induced from the administration of iced or hot water in vivo, we present a set multiple regression equations between the iris temperature and the ambient, tympanic, rectal, mean skin and forehead temperatures. Under the steady state and the unsteady state, the iris temperature could be the indication of the core temperature. Under the steady state, the tympanic temperature would be a function of the iris and mean skin temperatures. Under the nusteady state, the maximum deviation of tympanic temperature would be a function the maximum deviation of the iris and rectal temperatures. Less
