摘要 本文应用数理统计原理,系统地阐述了研究列车到达流和卸截流的分布规律的方法与步骤。根据卸载流的特点,提出了位移统计法。通过几个典型实例的统计分布研究,以及对大量的实测数据和历史资料的统计分析,得出井底车场列车到达流和卸截流一般均服从负指数分布这一规律。 A systematic exposition is made of the mathematically statistical methods and step concerning studies of train arrival flow and unloading flow at a shaftbottom station.Based on the characteristics of train unloading flow,a displacement method is advanced. After discussing statistical distribution of several typical examples and analysing great quantities of data and past records,it is concluded that train arrival flow and unloading flow are in mst cases of a minus exponential distribution
