In contrast to the cold weather on the day, the students generated a scotching hot atmosphere.

天气虽然很冷，但是一点都没有影响同学们热火朝天的气氛。

In combination with precision motion control and laser scanning along axle and circular direction, the method can classify and recognize the defects of scotching and flaking on wheel tread.

再结合精密运动控制，以及车轴和圆周方向的快速激光扫描，实现了踏面擦伤和剥离等缺陷参数的分类和识别。
