【摘要】 本文对国内５个铀矿山１９８８～１９９３年间２０６５７个平衡因子Ｆ值进行了统计分析。结果表明，平衡因子Ｆ按各矿实测样品数加权的总平均值为０．３３，文中同时给出平衡因子Ｆ值每年逐月的变化更多还原

【Abstract】 The statistical results of 20 657 equilibrium factor F values from 1988～1993 in 5 uranium mines of China indicate that total mean value of equilibrium factor F weighted by number of measuring samples in these mines is 0 33.Monthly variation of equilibrium factor F value in each year is also given in this paper.
