摘　　要：分析双线自动闭塞区段单列旅客列车及复合客车组扣除系数的构成和影响因素。针对具体区段通过计算机铺画满表运行图,采用图解法分析各种因素对客车扣除系数和通过能力影响的变化关系。结果表明:扣除系数随追踪列车间隔的减小而增大,随旅客列车对数的增加而减小且呈线性变化趋势;扣除系数及其变化幅度与旅客列车速度成正比关系;扣除系数随提速客车比例的增加先增大后变小,但变化幅度不大。通过不同区段大量的模拟分析,得出不同客车速度、不同客车对数和不同追踪列车间隔下的扣除系数取值。This paper analyses the composition and influence factors of the reduction coefficient of the single passenger train on the automatic block section of doubletrack line and the complex passenger train sets. Through working out train diagram with maximal line capacity by computer for a specific railway section, the relation of variation has been analyzed by illustrations about the factors affecting the reduction coefficient of passenger train and the line capacity. The results show that the reduction coefficient increases with the number of passenger trains in a linear relations but inversely with the train headway. The reduction coefficient and its change amblitude are proportional to the speed of passenger train. With the increase of the ratio of speedup passenger trains, the reduction coefficient increases first and then decreases, but the variation is small. Based on a large amount of simulations for different railway sections, reduction coefficients are obtained for different passenger train speed, different number of passenger trains and different train headways. 
