建立一台可测定生物体体表热导系数的试验装置。首先试验测定标准试样一新鲜甘油(AR级)及熔融石英玻璃(99.9% SiO2),其结果与 TPRC推荐值偏差≤ 0.7%;其次用试验方法证实本文所利用的Takegoshi理论模型的适用性;最后,根据生物活体会产生代谢热并维持恒定体温的特点,指出应用本装置去测定生物活体体表热导系数时必须满足的若干前提条件。
Establish a test device that can determine the thermal conductivity of the body surface of a living body. First of all, the standard sample of fresh glycerin (AR grade) and fused silica glass (99.9% SiO2) were determined. The result was less than 0.7% deviation from the recommended value of TPRC. Secondly, the experimental model was validated by Takegoshi’s theoretical model Finally, according to the characteristics that the biological living body can produce metabolic heat and maintain a constant body temperature, some preconditions that must be satisfied when using the apparatus to determine the thermal conductivity of the biological body surface are pointed out.
