身体热状态的分度及其在评价个体热防护装备中的应用

Graduation of Thermal State of the Body and its Use in the Evaluation of Personal Heat Protective Equipments

本文介绍了在不同热负荷下,身体所处的热生理功能状态,作了明确的5级分度。即分为舒适、温热及轻度、中度和重度热负荷状态。采用直肠温度、平均皮温、出汗率、心率及热积等5项生理指标,作为评定基础。并利用多元判别方法,建立了对5项生理指标的综合评价指数。已较好地用于评价个体热防护装备。

Physiological thermal state of the body was graduated onto five stages. They are respectively thermal comfort state, warm state, and light, middle and heavy heat load states. Rectal temperature,skin temperature, sweat rate, heart rate and heat store were used as physiological basis for the evaluation. And a complex evaluation index for the above five physiological indices was established by multivariate regression. It has been used successfully in the appraisal of personal heat protective equipments.
