摘　　要：水文频率计算中，经验频率对适线法的结果有重大影响。目前，国内外已有多种多样的经验频率公式。为了探索这些公式的来源和近似程度，本文作了回顾性的分析，并详细讨论了Г分布次序统计量情况下的经验频率值，提出了便于应用且近似性较好的经验频率公式。In frequency computation of hydrology, empirical frequency has a significant effect on the results of the curvefitting method. Now, there have been various types of empirical frequency formulas in China and other countries.In order to research the source and approximation of these formulas. this paper will make a review and analysis,discuss the empirical frequency values under the condition of Г-distribution order statistics. Otherwise, the empirical frequency formula given in this paper has a good approximation and is simple for application.
