【摘要】 为明确不同极端低温环境与防护装备下,日间清醒和夜间睡眠状态下各部位皮肤温度变化特征,在-16℃～-30℃极端低温环境下,采用皮温测量系统对实验对象5个代表性部位(胸部、手臂、大腿、小腿和脚趾)皮肤温度进行测试。结果表明:日间测试胸部温度相对最高,大腿和小腿在实验中后期出现温度反转。夜间除脚趾外,各部位皮肤温度变化差异较小,大腿温度相对最高,小腿温度与其他部位分离。研究结果可为低温环境下防护服研发与保暖效果评价提供参考。更多还原

【Abstract】 In order to clarify the change characteristics of skin temperature at various parts in the daytime awake and night sleep states under different extreme low-temperature environments and protective equipments, the skin temperature measurement system was used to measure the skin temperatures of five representative parts of experimental subjects, including the chest, arm, thigh, calf and toe, under the extreme low-temperature environment from-16 ℃ to-30 ℃.The results showed that in the daytime tests, the chest temperature was relatively the highest, and the thigh and calf temperatures reversed in the middle and late stages of the experiment.In the night tests, the skin temperatures change of various areas had little difference except the toe, the thigh temperature was relatively the highest, and the calf temperature was separated from other parts.The research results provide reference for the research and development of protective clothing and the evaluation of thermal insulation effect in low-temperature environment.更多还原
