摘　　要：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。An experimental apparatus for measuring the effective thermal conductivity of the body surface has been built. The following tests have been completed to demonstrate the apparatus validity. Firstly, as the standard specimen, glycerine (AR) and fused quartz glass (99.9% SiO2) were respectively measured, and the relative errors compared with TPRC recommended date are less than 0.7%. Secondly, as a base of the apparatus, the validity of Takegoshi theory model was confirmed using the experimental method for inorganic specimens. Lastly, for the biological bodies characterized by metabolic heat generation and unchanged body temperature, some prerequisites for the application of the technique to measuring their thermal conductivity were discussed.
