为探讨舱温降低对人体的影响，观察了穿着不同热阻服装的５名男性青年受试者在２０℃、１５℃、１０℃三种舱温条件下，直肠温度、皮肤温度、皮肤热流、体表红外热图等指标的变化。结果表明，随着舱温的下降，平均皮温及肢端温度显著降低，体表热流明显增高，皮肤红外热图分布也有明显改变。２０℃舱温主观感觉舒适；１５℃舱温主观感觉较凉；１０℃舱温感觉冷，热债增为１４４ｋＪ／ｍ２，处于轻度冷耐受状态。提示对密闭舱室舱温下限的确定有实用价值。
In order to explore the effect of lowering of cabin temperature on the human body, we observed the effects of rectal temperature, skin temperature, skin heat flux, Body surface infrared thermograms and other indicators of change. The results showed that with the decrease of the cabin temperature, the average skin temperature and extremity temperature decreased significantly, the body surface heat flux increased obviously, and the skin infrared heat map also changed obviously. 20 ℃ cabin temperature subjective feeling comfortable; 15 ℃ cabin temperature subjective feeling cooler; 10 ℃ temperature feel cold, hot debt increased to 144kJ / m2, in a mild cold tolerance. Prompt on the determination of the lower limit of the temperature of the airtight compartment has practical value.
