衣服の着用快適感評価装置の開発

研制了一种新型的用显微镜观察发汗的发汗胶囊，用于测量热不稳定状态下的发汗量和发汗频率。在50 ml/min的干燥氮气条件下，湿度传感器的时间常数为0.91*0.06秒，皮肤表面有汗液后传感器开始工作的滞后时间为0.73*0.04秒。由于湿度传感器可以在几秒的周期内检测到周期性的湿度变化，因此这种新型出汗胶囊适用于热非稳态下局部出汗率的测量。所有实验均在恒温室内进行，受试者均为健康的男性和女性。操作温度保持在32℃，从地板到天花板的风速控制在0.1 m/秒。实验开始几分钟后，环境蒸气压由18mmhg变为25mmhg。保持这种状态15分钟后，血压再次降至18mmhg。一次会议的总时间是65分钟。用显微镜拍摄的更多照片显示，一些汗珠在几秒钟内周期性地变大变小，而另一些则保持不变。利用快速傅里叶变换对局部汗液率数据进行分析，得到了典型的功率谱分布。低频区功率谱为1/f型，高频区功率谱为1/f^2型。利用新型出汗胶囊测量的局部出汗率数据，通过快速傅里叶变换分析，很有可能对出汗类型进行分类。另一项研究旨在通过对虹膜温度的非接触式测量获得一些关于核心温度的信息。虹膜温度可能显示核心温度，因为血液从颈内动脉经过虹膜。在三种不同的实验条件下，我们用辐射温度计测量了男性和女性受试者的体温，用热敏电阻测量了鼓室和直肠温度，用铜-康铜热电偶测量了局部皮肤温度。在体内由冰水或热水引起的热稳态和非稳态下，我们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一组多元回归方程。在稳态和非稳态下，虹膜温度可以作为堆芯温度的指示。在稳定状态下，鼓室温度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。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
