摘要
10名男性受试者穿着战斗机飞行员不同配套防护服,在不同热环境中完成70次实验。结果表明,当受试者在30℃和35℃条件下暴露90min时,热应激强度随着服装热阻值增加而增大。但是受试者在45℃高温环境中停留30min时,未显出服装热阻值对热应激的影响。以综合热应激指数3.40作为飞行员热应激安全限,评定了热应激程度:DB30℃、WB26℃属轻度热应激,DB35℃、WB28℃为中等度热应激,DB45℃、WB31℃是重度热应激。本研究结果可作为制定飞行员夏季热负荷标准的依据。
Seventy experiments of ten young male subjects wearing fighterpilots' different complements of protective garments in different hot env-ironments were made. The results showed that the heat stress wasincreased with the insulations of the garments when the subjects had beenexposed to the environmental conditions of 30℃ and 35℃ for 90 minutes;but no significant differences were found between the heat stress and theinsulation while the subjects were exposed to the hyperthermal environm-ent of 45℃ for 30 minuts. Taking the combined index of heat stress3.40 as a safe heat stress limit for pilots, we suggested the evaluatingcriteria of the levels of heat stress to be: DB 30℃ and WB 26℃ as lightheat stress; DB 35℃ ahd WB 28℃ as moderate heat stress; DB 45℃ and WB 31℃ as severe heat stress. The results of the study can beregarded as a basis for establishing the criterion of piot's heat load.
