研究了3种扩大囊覆盖面积抗荷服的热负荷。这3种抗荷服的抗荷囊覆盖下体面积分别为43%，65%和90%(以下用Ⅰ、Ⅱ、Ⅲ组表示)。5名健康男性战士分别在30，35，40℃环境中穿着3组装备暴露60或90 min。测量心率、皮肤温度、直肠温度、出汗量等。以综合热应激指数(CIHS)评定热应激程度。受试者的心率、皮肤温度、直肠温度、出汗量均随着环境温度的升高而增加。各种生理指标的变化均以Ⅲ组为大。受试者配穿Ⅰ、Ⅱ、Ⅲ组装备在30℃环境中90 min时的CIHS分别为3.31，3.08，3.61，均属轻度热应激；35℃条件下90 min时的CIHS分别为4.86，4.49，5.15，均属中度热应激；40℃暴露第60 min时的CIHS分别为5.77，5.47，6.08，均已接近重度热应激。以上结果提示，配穿扩大囊覆盖面积的抗荷服，必须通风散热，否则，限制热暴露时间。另外，分体式抗荷服比连体式抗荷服的热负荷小。

The heat loads of three extended bladder coverage anti-G suit(EBCAGS)were studied.The coverage of lower body of EBCAGS ranged 43%,65%,and 90% for groupⅠ,Ⅱ,and Ⅲ respectively.Five healthy male soldiers voluntarily wearing three EBCAGS were exposed to 30℃,35℃ and 40℃ for 60 or 90 min.Heart rate,rectal temperature,skin temperature and sweat quantity etc were determined.Heat stress was evaluated according to combined index of heat stress(CIHS).All physiological variations in group Ⅲ were the biggest.Each of above mentioned physiological indexes increased as the environmental temperature raised.The CIHSs of the subjects wearing group Ⅰ,Ⅱ and Ⅲ at 30℃ for 90 min were 3.31,3.08 and 3.61 respectively,i.e. light heat stress.While at 35℃ for 90 min,t he CIHSs were 4.86,4.49 and 5.15 respectively,belonging to moderate heat stress.The CIHSs at 40℃ for 60 min were 5.77,5.47 and 6.08 respectively,approaching to serious heat stress.Obviously,pilots wearing EBCAGS must be ventilated.In addition,the heat load of the body-separated anti-G suit was less than the body-joined one.
