目的 评价飞行员配穿囊式抗荷服在不同代谢水平、不同环境温度条件下的温度舒适性。 方法 6名受试者分别以不同的代谢水平暴露于 2 0℃、2 5℃和 35℃环境 ,配穿装备为KH 3抗荷服和KH 7抗荷服。每次试验 70min。采用微小气候评定装置测量衣下温度和衣下潮湿率 ,并以 3种主观感觉评定温度舒适性。 结果 试验期间 ,Ⅲ组 (或Ⅳ组 )的衣下温度增值和衣下潮湿率增值均无显著性意义。Ⅰ组 (或Ⅱ组 )、Ⅴ组 (或Ⅵ组 )、Ⅶ组 (或Ⅷ组 )分别与Ⅲ组 (或Ⅳ组 )比较 ,衣下温度增值、衣下潮湿率增值均有显著或非常显著性意义 (P <0 .0 5或P <0 .0 1)。Ⅰ组 (或Ⅱ组 )与Ⅴ组 (或Ⅵ组 )的衣下温度增值、衣下潮湿率增值均有显著性意义 (P <0 .0 5 )。Ⅰ组～Ⅷ组的衣下温度、衣下潮湿率作比较 ,Ⅶ组 (或Ⅷ组 )与其它各组的增值均有非常显著性意义 (P <0 .0 1)。 结论 在一定的环境温度范围内 ,代谢水平可以比环境温度更能影响人体的温度舒适性。 2 0℃环境中 ,飞行员配穿KH 3抗荷服和KH 7抗荷服飞行时 ,衣下微小气候是不适宜的。在 2 5℃环境下从事低代谢率活动时 ,对温度舒适无显著性影响。 35℃环境中 ,即使从事低代谢水平活动 ,也将严重影响飞行员温度舒适。
Objective To evaluate the temperature comfort of pilots with capsized anti-G clothing at different metabolic levels and different ambient temperatures. Methods Six subjects were exposed to 20 ° C, 25 ° C and 35 ° C at different metabolic levels, respectively, and were fitted with KH 3 anti-kits and KH 7 anti-kits. Each test 70min. The micro-climate assessment device was used to measure the temperature of the undergarment and the moisture content of the undergarment and to evaluate the temperature comfort in three subjective ways. Results During the test period, there was no significant difference in the value of under-coat temperature and the increase of wetness rate between clothes in group Ⅲ (or group Ⅳ). Compared with group Ⅲ (or group Ⅳ), group Ⅰ (group Ⅱ), groupⅤ (group Ⅵ), group Ⅶ (or group Ⅷ) had significant or very significant increment Sexual significance (P <0.05 or P <0.01). Group Ⅰ (or group Ⅱ) and group Ⅴ (or Ⅵ group) under the clothing temperature value, underwear moisture value increased significantly (P <0. 05). Group Ⅰ to group Ⅷ under the clothing temperature, moisture under the clothes for comparison, Ⅶ group (or Ⅷ group) and other groups added value has a very significant (P <0.01). Conclusion In a certain range of ambient temperature, the metabolic level can affect the temperature comfort of the human body more than the ambient temperature. In the environment of 20 ℃, pilots wear KH 3 anti-khaki and KH 7 anti-kimono flight, the micro-climate under the clothes is not suitable. At 25 ℃ environment engaged in low metabolic rate activity, no significant effect on temperature and comfort. 35 ℃ environment, even in low-level metabolism activities, will also seriously affect the pilot’s temperature comfort.
