摘要
实验结果表明,人体出现冷感的气温,安静坐位为5℃,蹬车运动为- 5℃;手指血流图和耳垂脉搏波产生显著变化的环境温度,静坐为5℃,运动为-5℃;肢体皮肤温度出现显著变化的环境温度,于静坐和运动状态分别是气温0℃和-5℃;裸露部位皮肤温度发生明显变化的气温界限静坐和运动均为10℃;手操作功能出现显著变化的环境温度静坐为5℃,运动为-5℃或-10℃。兔血中IgA含量测定亦表明,机体免疫功能发生明显改变的温度界限是5℃,与人体实验结果类似。根据劳动时间率和环境温度,提出了低温作业分级标准。
The results of experiment showed that the temperature of human
beings'coldfeeling appeared at 5℃ for seating and-5℃for pedalling;
Temperature for significant change of Rheolimbgram of the finger and
pulse wave of earlobe were also 5℃ for seating and -5℃for pedalling.
The environmental temperature for obvious change of skin tempera-
ture of the limbs were 0℃ and -5℃ respectively; The limit of temper-
ature in nude parts of the body was 10℃ for both seating and pedal-
ling;The environmental temperature causing significant change of opera-
ting function of hands were 5℃ for seating and -5℃or-10℃ for
pedalling; The results of measurement on serum IgA of rabbit also de-
monstrated that the temperature limit for obvious change of immunolo-
gical function were 5℃,it was similar with the human being results.
Based on groat amount of information from laboratory research, the
classified standard of work with low temperature were recommended.
