【摘要】 本实验在72点测温基础之上计算出标准参考平均皮肤温度,以此对8个以往的人体加权平均皮肤温度测算方程进行了比较。发现其中一些测算方程在冷环境下应用的可靠性较差。本实验得出的两个新方程优于某些以往的方程,具有测温点少,可靠性高等特点,常温低温下均适用,尤其适用于冷环境中。更多还原

【Abstract】 Eight existing and two new formulas obtained from present study for calculating the weighted mean skin temperature (Ts) of men have been compared with the reference mean skin temperature (Tref). The Tref was a mean of 72 temperature measurements weighted according to the regional distribution of body surface area, The skin temperature data were taken from experiments on 6 clothed resting subjects at ambient temperature of 15, 5 and -15℃, It was found that, at -15℃, amongst the existing formulas only the results of 20-points method of Hardy and DuBois had an agreement of near 80% within ±0.5℃ with the Tref, while the others all showed a poor agreement frequency of about 50% or less, However, the two newly developed formulas each involving 12 or 11 measuring points agreed reasonably with Tref over the full range of ambient temperature in this study (agreement frequency ranged from 80.8 to 96.2%) , Because of the lesser measuring sites and higher correctness in estimating the Ts, it was concluded that they are suitable for use in temperate to cold environments for clothed subject.更多还原
