摘　　要：制动距离限值是列车(包括机车、车辆)制动系统设计的依据,也是布置信号机、确定闭塞分区长度的依据;制动系统的性能决定列车的制动能力,轮轨黏着允许限度及车轮和闸瓦的制动功率极限限制了列车的制动能力;制动距离限值、铁路通过能力及以上几个方面互相影响、互为因果、互相制约。The braking distance limit is the basis of designing the train(including locomotive and rolling stock) braking system,as well as the basis to arrange signal device and determine the length of blocking section. The performance of the braking system determines the braking capacity of train. The permissible wheel-rail adhesion limit,the ultimate braking power of wheels and brake shoes restrict the braking capacity. The braking distance limit,the railway passing capacity and the several aspects above interact as both cause and effect,affect mutually and restrict mutually.
