High speed railsurface corrosion in the form of electroplating, hot dip, spray, dip, dip galvanized. High speed rail use effect.
高速护栏表面防腐形式有电镀、热镀、喷塑、浸塑，镀锌后浸塑。高速护栏使用效果。

Testing signal is very sensitive to the lift off effect in the hardness nondestructive testing of railsurface by electromagnetic method, so lift off effect must be restrained.
电磁无损检测钢轨踏面硬度中，检测信号对提离效应极其敏感，所以必须对提离效应加以抑制。
3
An adhesion coefficient of less than 0.27 would be appropriate under dry railsurface condition.
