头颈部皮肤红外热图的医学研究

本文利用红外技术, 研究在两种气温下头颈部体表温度分布的特点和变化的规律.发现头颈部皮肤可以根据受气温影响的程度, 分为热稳定区和热不稳定区两部份.这一特点对体温调节的基础性研究以及为设计航天员使用的液冷帽关于流量分配及流向确定等方面, 均具有理论和实际的指导意义. 

Studies of Infra-thermogram of the Head and Neck

The characteristics of the skin temperature distribution in the head and neck regions under two different air temperatures are researched. According to the degree of the effects of air temperature on them, the. distribution in the head and neek regions can be divided into thermostable and thermolabile areas. By computer processing, the result of digital image displays of temperature show that skin temperature presented in irregular and large lumped or small scattered distribution. The latter condition more often occurred under the air temperature of 20℃. By statistical measures, mean skin temperature under higher air temperature has the following features: the temperature of the frontal part is higher, that of the lateral part is moderate, while that of the back part is lower. When the air temperature lowered down, the differences among these parts do not remain, but the surface temperature of each corresponding part still show the ability in changing skin temperature under the influence of air temperature. The characteristics of skin temperature distribution in the head and neek regions has a practical significance for the design of personal protective equipments such as liquid-cooled cap etc.
