体温升高可造成生理机能障碍和生产率下降,因而许多科学家正在努力研制一个有效的外部降温系统来防止这种危害。全部使用空调在目前尚难以实现,采用个体降温措施还存在着两个有争论的问题即:空气降温还是液体降温;全身降温还是局部降温。虽然关于个体降温措施的调查研究已经开始了二十多年,但至今仍未能得到理想的结论,因此本实验在相同的干热(50℃,30％相对湿度)环境中检验了七种降温措施的效果,根据所引起的生理学作
Increased body temperature can cause physical dysfunction and decreased productivity, and many scientists are working hard to develop an effective external cooling system to prevent this harm. All the use of air conditioners is still difficult to achieve at present, the use of individual cooling measures there are still two controversial issues that are: air cooling or liquid cooling; body cooling or local cooling. Although more than twenty years have passed since the investigation of individual cooling measures, so far no satisfactory conclusion has been reached. Therefore, in this experiment, seven kinds of cooling tests were conducted under the same dry heat (50 ° C, 30% relative humidity) The effect of the measure, according to the physiology made
