摘要 目的：在热环境和中等运动负荷条件下，比较和量化穿着两种透气式舰员防毒服(新NC服和现HC服)人员的热应激反应和机体的热负荷状态。方法：受试人员为8名未经热习服锻炼的男性战士。在热环境中，受试人员分别着两种实验服装进行跑台步行运动试验；步行的速度和坡度分别为1.11 m/s和5%，试验持续时间为80分钟。监测指标包括：直肠温度(T_re )、皮肤温度(T_sk )、热蓄积率(ΔS)以及出汗率和汗蒸发率等。结果：与着HC服相比，着NC服时受试人员的T_re 、T_sk 和ΔS响应显著增加，出汗率和汗蒸发率没有显著差异。结论：受试人员在着NC服时产生了更强的热应激反应，机体的热负荷也更高，同时受试人员主诉着NC服比着HC服感到更不舒适。

Comparison of thermo-physiological effects between wearing two different types of permeable navy protective clothing Ding Songtao, Pan Chaorong, Zhu Xiansen, et al. PLA Research Institute of Chemical Defence, Beijing 100083

     Abstract Aim: To compare and quantify the physiological heat stress of personnel wearing two different types of permeable navy protective clothing(the new NC suit and the current HC suit) in hot environment. Methods: Eight heat unacclimatized male soldiers(20.0 ± 0.8y,1.71± 0.04m,63.8± 5.7kg) wearing the two test suits separately were exposured for 80 min to a climatic condition of 34℃ and 53% RH while performing a workload of continuous treadmill walking at the speed of 1.11 m/s and a slope of 5%. During the exposure period, rectal(T_re ) and skin(T_sk ) temperatures and heat storage rate(Δ S) of the test subjects were monitored every 5min. At the completion of each test, sweat loss and self-reported symptoms were recorded. Results: Significant (P< 0.05) NC vs HC differences were observed in the physiological responses and heat balance parameters: T_re was 1.01± 0.08℃vs 0.82± 0.17℃ ......
