局部热暴露对人体热反应的影响研究(1):局部热感觉对全身热感觉的影响
Effect of local exposure on human thermal responses(1):effects of local thermal sensation on overall thermal sensation
摘要:
随机选取30名男性受试者,在中性偏热的房间中,局部冷气流分别作用于脸部、胸部和背部,采用问卷调查的方法以一定的时间间隔记录了受试者身体各个部位的局部热感觉和全身热感觉。结果表明,局部热暴露在改变暴露部位和全身的热感觉的同时,也显著改变了非暴露部位的热感觉,据此提出了基于影响因子的分析方法和全身热感觉的预测模型。
Abstract:
At the room temperatures ranging from neutral to warm, three sensitive body parts—the face, the chest and the back of 30 randomly selected male subjects are each exposed to local cooling air. Records local thermal sensations of each body part and overall thermal sensation at regular intervals by questionnaires. The results show that local exposure affects not only thermal sensations of the exposed body and the whole body, but also thermal sensations of the unexposed body parts. Proposes a new influencing factor method and a predicted model for overall thermal sensation based on the method.
