在高温条件下工作的工人,由于外界环境空气温度的改变,体内物质代谢的强度和性质亦将发生变化、过去有许多研究报告,认为高温条件下机体对维生素B_1、维生素B_2和维生素C的需要量增加①。根据我院高温作业研究组历年对高温作业工人营养向题的研究结果,亦发现高温作业工人维生素B_1、维生素C营养状况较一般工人为差②。所以对高温作业工人应该补充一定数量 Due to the change of ambient air temperature, the intensity and nature of metabolism in the body will also change. There are many reports in the past that the body needs vitamin B 1, vitamin B 2 and vitamin C under high temperature conditions Increase the amount of ①. According to the research results of high temperature work group in our hospital over the years on the nutritional status of workers at high temperatures, we found that the nutritional status of vitamin B_1 and vitamin C in workers under high temperature was worse than the average workers. Therefore, high-temperature workers should add a certain amount of work
