高温、振动、噪声复合应激时人体体温调节改变及数学模型

CHANGES AND MATHEMATICAL MODELS OF HUMAN THERMOREGULATION UNDER COMBINED STRESS OF HIGH TEMPERATURE,VIBRATION AND NOISE

本研究表明，高温、振动、噪声复合因素使受试者的平均皮肤温度、直肠温度和出汗量显著增加。在此基础上，我们建立了高温、振动、噪声复合应激时人体皮肤温度、直肠温度和出汗量的数学模型。这些模型提示，上述复合应激与体温调节之间呈非线性关系。统计分析表明，这些数学模型可信度高。上述模型在航空工程设计及环境医学方面有较高的实用价值。

Experiments showed that combined factors of high temperature,vibration and noise may cause remarkable increase of the mean skin and rectal temperature and amount of sweat.On the basis of these results, mathematical models were designed for human skin temperature,rectal temperature and amount of sweat under the combined stress of high temperature,vibration and noise. The models indicated that non-linear relationships were shown between above mentioned combined stress and the thermoregulation. The statistical analysis showed these models were highly reliable. The models have high practicability in aeronautical engineering design and environmental medicine.
