摘要
Gagge两节点模型在预测环境对人体产生的整体热影响时具有相当的准确性,能满足大多数工程研究及热舒适评价的需求,该模型在实际应用中认可度较高。但是在低气压环境下,人体周围的环境参数及人体的一些生理参数发生了变化,直接应用二节点模型会存在一定问题。因此,本文通过高原低压舱模拟低气压环境,对Gagge两节点模型在3 000 m内的无症状高原反应域低气压环境下的适用性进行了实验研究,同时对两节点模型进行低压下的改进,并对改进后的模型进行验证,结果表明,皮肤温度的测量值和模拟值吻合较好,改进后的两节点模型在低气压环境下应用的准确性较高。
The two-node model can be used to predict physiological responses or responses to transient situations accurately. However, the application of the two-node model is limited because of the change of environment and physiology parameters in low pressure environment. The two-node model used in low pressure environment, is studied by simulation of low-pressure environment of plateau. Meanwhile, the model is improved in order to be used in low pressure and tested. The results show that the calculated results are consistent with the experimental results. The improved model can be applied to the low atmospheric pressure environment and gives a more accurate result.
