冷水作业分级标准的研究——Ⅰ.冷水浸手的生理反应及温度限值

The research on classified standard of work in cold water Ⅰ.The physiological effects on hands immersed in 3～20℃ cold water

对18名受试者进行了20℃、18℃、15℃、13℃、12℃、10℃、8℃、5℃和3℃共9组冷水浸手生理实验。结果表明显著影响心率差值、手指皮肤温度、知觉、操作功能和冷感率的冷水温度主要在10℃及以下。据此,建议把10℃作为划分冷水作业的温度限值。

The physiological effects on hands immersed in 20℃, 18℃, 15℃,13℃,12℃, 10℃, 8℃,5℃ and 3℃ cold water were studied on 18 subjects.The results showed that heart rate value, body temperature, skin temperature,skin consciousness, cold feeling and operative function were affected significantly under 10℃cold water.
