摘　　要：本文论述了蠕滑率与粘着系数的关系;讨论了速度差V、加速度的导数dr/dt和加速度r三个参数的作用以及以dr/dt作为防空转修正信号和记忆最大粘着系数时电流的信号的优越性;分析了牵引电机串、并联的利弊以及8K机车轴重转移对粘着利用的影响;并具体介绍了8K机车的防空转、防滑行系统的电路框图、一些重要修改以及评价粘着利用的指标。The article describes the relation betwcen creepage and adhesion coefficient. It discusses the functions including velocity difference υ, acceeleration r and its derivative dr/dt, as well as the advantages of current signals when dr/dt is used as anti-slip correction signals and memorizing the highest adhesion coefficient. It analyzes the advantages and disadvantages of series and parallel connec tions of traction motor, as well as the effect of axle weight transfer on adhesion utilization of 8K electric locomotive. The article also gives the block diagram of anti-slip/slide system of 8K electric locomotive, some important amendments of the design and the criteria of the eva’uating adhesion utilization.
