【摘要】 人体长时间处于高温高湿环境中易引发热疾病，为评估室内高温高湿环境人体热应激水平，利用熵权法(EWM)确定平均皮肤温度(MST)、心率(HR)、口腔温度(OT)、耳膜温度(TT)测量参数的权重，基于多准则妥协解排序法(VIKOR)模型建立新的综合评价指标QI,与主观参数、环境参数进行拟合以验证QI的合理性，通过改进生理应激指标(PHSI)的热应力强度分级确定QI的分级。结果表明：TT、MST、OT、HR的权重范围分别为0.151 9～0.421 1、0.193 5～0.345 2、0.160 4～0.426 9、0.134 8～0.339 1,MST的权重均值较高，受环境因素及劳动因素影响较大；QI的安全范围[0,0.36),热耐受范围[0.36,0.57],危险范围(0.57,1]。更多还原

【Abstract】 The human body is susceptible to heat diseases when exposed to high temperature and high humidity for a long period of time. In order to assess the level of human heat stress in indoor high temperature and high humidity environments, the paper utilized the EWM to determine the weights of measurement parameters such as Mean Skin Temperature(MST), Heart Rate(HR), Oral Temperature(OT) and Tympanic Temperature(TT). A new comprehensive evaluation index QI was established based on VIKOR model. The reasonableness of QI was validated by fitting with the subjective parameters and the environmental parameters. The grading of QI was determined by improving the thermal stress intensity grading of the physiological stress indicator PHSI. The results show that the weight ranges of TT, MST, OT and HR are 0.151 9-0.421 1, 0.193 5-0.345 2, 0.160 4-0.426 9 and 0.134 8-0.339 1, respectively. MST has a high mean value of weight, which is greatly affected by environmental factors and labor factors. QI’s safety range [0,0.36), thermal tolerance range [0.36,0.57] and hazardous range(0.57,1].更多还原
