摘　　要：列车制动摩擦材料的制动效果不能光看摩擦系数的大小,制动效果的最终表现是制动距离的长短。高摩闸瓦(片)和高磷闸瓦的摩擦系数差别较大,而在速度90 km/h以下时,其制动距离却相差甚微。两者制动距离的差别主要表现在更高的速度段。Brake effect of Train brake friction material is not decided by the coefficient of friction completely, the ultimate performance of braking effect is the length of braking distance. Mount High abrasion brake block and High - phosphorous brake shoe difference was not significant, but less than 90 km/h speed, its braking distance is little difference. The main difference between the two braking distance performance higher speed.
