It points out that the antislide system of this type of locomotive mainly controls the macro sliding. Therefore, the resistance brake performance of the SS4 eclectic locomotive should be further improved if the issue of abrasion is to be resolved.

• 同时指出 ,由于SS4改进型电力机车防滑系统主要抑制宏观滑行 ,因此 ,要解决动轮擦伤问题 ,就要进一步改善SS4改进型电力机车的电阻制动特性 ,一方面在进行电阻制动时 ,要防止励磁电流上升过快 ;
