The wheel flange wear is caused by the flange action of the wheel and rail whereas the double-groove wear on tread may be mainly caused by the break shoe .

轮缘磨耗主要是轮轨相互作用的结果，而 踏 面上的凹槽磨耗可能主要由 闸瓦制动引起。

According to the features of the slot between the wheel tread and the brake shoe we propose a method for the image inspection of brake shoe wear .

根据图像中车轮 踏 面 与 闸瓦之间存在弧形缝隙的特征，提出了闸瓦磨耗的图像检测方法。

Samples were collected from the upper surface the tread of right foot for each pair of shoe then inoculated and counted for the colonies .

对每双 鞋的右脚上表面和 鞋底取样，接种并计数菌落。

Via theoretical calculation on one side when the braking leverage is constant the causes to wheel tread flat in application of high phosphor cast iron brake shoe are analyzed ;

通过理论计算，一方面分析了在制动倍率不变的情况下使用高磷 闸瓦易出现 擦伤的原因；
