摘　　要：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。To study effects of cabin temperature on human body, changes in rectal temperature, local skin temperature, local skin heat fluxes and skin infrared thermogram were observed in 5 male subjects dressed in different thermal insulation clothings under 20℃、15℃ and 10℃ cabin temperatures.The results showed that,average skin temperature and tip temperature obviously dropped, and skin heat fluxes increased with falling of cabin temperature, and changes of local skin infrared thermogram were significant.Subjective feeling were comfortable and cool at cabin temperature of 20℃ and 15℃ respectively.While subjective feeling was cold and there was a thermal debt of body 144kJ/m 2 at 10℃ which indicated that it was slightly cold but tolerable. The results may be valuable in determining the lowest tolerable limit of cabin temperature.
