摘要/Abstract

摘要： 为深入探究高温高湿环境对人体产生的影响,利用环境舱模拟高温高湿环境并开展人体热应激试验,以获得试验数据。试验温度分别为34、36、38和40 ℃,相对湿度(RH)分别为60%、70%、80%和90%,综合口腔温度t_c、心率(HR)、皮肤温度t_sk 3个生理参数和热感觉投票(TSV)、疲劳程度得分(FS) 2个主观参数,提出综合生理指标F,根据各被试的F得分,应用聚类分析法对试验环境工况分类,用判别分析法建立判别函数确立分段界值。结果表明:由4个试验温度和4个相对湿度两两组合而成的16个高温高湿环境被分成了3类,此3类环境的F得分范围分别为28.14～39.76, 39.17～45.21, 44.13～52.39,将此3类环境划分为一般恶劣环境、中度恶劣环境和重度恶劣环境3个等级。

Abstract: In order to explore influence of high temperature and high humidity environment on human body, such environment was simulated and heat stress experiment conducted by using environmental chamber to obtain data. With temperature for experiment at 34, 36, 38 and 40 ℃,Relative Humidity (RH) at 60%, 70%, 80% and 90%, a comprehensive physiological index F was proposed based on three physiological parameters which were oral temperature (t_c), Heart Rate (HR), skin temperature (t_sk) and two subjective parameters, Thermal Sensation Vote (TSV) and Fatigue Score (FS). Then, experimental working conditions were classified through cluster analysis according to Fscore for each subject, and discriminant function was built using discriminant analysis to establish segmentation threshold. The results show that 16 high temperature and high humidity environments are classified into three types whose range of F score is 28.14-39.76, 39.17-45.21, 44.13-52.39 respectively. And they can be defined as generally harsh environment, moderately harsh environment and severely harsh environment

Key words: high temperature and high humidity environment, heat stress, factor analysis, cluster analysis, classification
