	<span style=\"line-height:1.5;\">本文以列车单轮对系统为例，设计了一组合理的轮轨黏着模型，从制动距离和耗风量指标出发，在低黏着轨面、紧急制动工况下，研究防滑器滑行检测判据改变对列车防滑性能的影响，涵括滑行检测里的减速度判据、速度差判据以及滑移率判据。研究结果表明，合理范围内分别提高各项判据阈值大小，会使列车滑行下的制动距离先降后升，压缩空气消耗量逐渐减小。<br />
Taking the train single wheel pair system as an example, a set of reasonable wheel-rail adhesion models was designed. Based on the braking distance and air consumption indexes, the slippage detection criteria of slippers were studied under low-adhesion rail surface and emergency braking conditions. The impact on the anti-skid performance of trains includes the deceleration criterion, speed difference criterion and slip rate criterion in coasting detection. The research results show that increasing the thresholds of each criterion within a reasonable range will cause the braking distance of the train to coast down and then increase, and the compressed air consumption will gradually decrease.</span><span style=\"line-height:1.5;\"></span>
