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１．１１ｍ／ｓ和５％，试验持续时间为８０分钟。监测指标包括：直肠温度（Ｔｒｅ）、皮肤温度（Ｔｓｋ）、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Ｔｒｅ、Ｔｓｋ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
OBJECTIVE: To compare and quantify the thermal stress response and the thermal load of the body wearing two kinds of breathable crew protective suits (new NC service and HC service) under hot environment and moderate exercise load. Methods: The subjects were 8 male warriors who did not exercise with heat. In the hot environment, the subjects were two kinds of experimental clothing running treadmill exercise test; walking speed and slope were 1.11m / s and 5%, the test duration of 80 minutes. Monitoring indicators include: rectal temperature (Tre), skin temperature (Tsk), heat accumulation rate (ΔS) and sweat rate and sweat evaporation rate. Results: Tre, Tsk and ΔS responses were significantly increased in subjects with NC clothing compared with those in HC clothes, with no significant differences in perspiration rate and sweat evaporation rate. Conclusion: The subjects in the NC clothing produced a stronger heat stress response, the body’s heat load is also higher, while the subjects complained NC clothes than HC clothes feel more uncomfortable
