为了解煤矿井下工人维生素Ｂ１、维生素Ｂ２、维生素Ｃ（以下简称ＶＢ１、ＶＢ２、ＶＣ）的需要量，用饱和试验法对工人该三种维生素的需要量进行了初步调查；受试对象经过７天饱和期后，分别给予四个试验组和一个对照组不同剂量三种水溶性维生素，结果表明，当每人每日摄入ＶＢ１３．４９ｍｇ、ＶＢ２３．２２ｍｇ、ＶＣ１１８ｍｇ时，其４小时负荷尿中的排出量分别为４９１．５ｕｇ、１２５６．８ｕｇ、２６．８ｍｇ，与对照组比较差异有高度显著性（Ｐ＜０．０１）。可认为上述三种维生素的每日摄入量为该矿井下工人的适宜需要量。
In order to understand the requirements of vitamin B1, vitamin B2 and vitamin C (hereinafter referred to as VB1, VB2 and VC) in coal mine workers, the requirements of workers for the three vitamins were investigated by saturation test. After seven days Saturated period, were given four experimental groups and a control group of different doses of three kinds of water-soluble vitamins, the results show that when the daily intake of VB13.49mg, VB23.22mg, VC118mg, 4 hours of loading urine The discharge volume was 491.5ug, 1256.8ug, 26.8mg respectively, which was significantly higher than that of the control group (P <0.01). The daily intake of these three vitamins can be considered as the appropriate requirement of workers in the mine.
