摘要
论述了身体各部位组织的基础代谢、基础血流及基础热容量等热生理特征，改变气温和风速对身体各部位体表温度的影响，各部位致冷效能和效率的比较，及活动强度和致冷介质对各部位致冷效能的影响等。从而提出了两种全身液冷服（ＬＣＧ）的流量分配比例。即Ⅰ型为头颈部２０％、躯干３５％、上肢１５％、下肢３０％；Ⅱ型为头颈部２０％、躯干２５％、上肢１５％、下肢４０％。
This study was designed to demonstrate thermal
physiological featuresof basal metabolism , basal blood flow and basal heat capacitance in
different parts of thebody; The influences of ambient temperature and wind on skin temperature
were also in-vestigated。 Comparison was made among effectiveness and efficiency of
cooling of vari-ous parts of the body , and influence of physical activities and cooling medium
on the ef-fectiveness of cooling was also estimated。 Basing on these findings , two ways of
distribu-tion of the total cooling in whole-body liquid-cooled garments are suggested :(1)
head-neck 20%, torso 35%, arms l5%and legs 30%。 It is suitable for heat load of
aircraftcockpits etc。(2)Head-neck 20%, torso 25%, arms 1 5%and legs 40%。 It is suitablefor
physical activities in manned spaceflight or warship etc。
