摘　　要：介绍我国客货列车空气制动力的计算参数。论述制动力计算中的基础制动装置计算传动效率、实算闸瓦压力和闸瓦实算摩擦系数的成套性。指出《列车牵引计算规程》规定的实算摩擦系数是根据实算闸瓦压力试验出来的,而试验时用的实算闸瓦压力又是按基础制动装置的计算传动效率计算的,所以在计算列车空气制动力时,其中的实算闸瓦压力必须用计算传动效率计算。否则不能得出正确的计算结果。The calculation parameters of air braking force for passenger train and freight train are introduced and the complete set properties for foundation braking rigging calculating driving efficiency and actual eomputative brake shoe pressure and actual computative brake shoe friction co- efficient of braking force calculation are discussed. According to actual computative brake shoe pressure, the actual computative friction coefficient of the stipulations of （（Regulations on railway train traction calculation）） are received by experiment, but actual computative brake shoe pressure in test is calculated by calculating driving efficiency, so that the actual computative brake shoe pressure must be calculated by calculating driving efficiency for train braking force calculation,otherwise the correct calculation result can＇t be obtained.
