N a very accurately ground block of hardened steel used to measure a gap with close accuracy: used mainly in tool-making and inspection 滑轨
But at the gauge face of the rail, high levels of slip and gravity inhibit the formation of protective layers.
但是在钢轨的内侧面，由于车轮经常滑动和重力延缓了保护层的生成。
Place the gauge on a horizontal, flat , non-slip surface . Stir the sample homogeneous with small palette knife , and the pour sufficient liquid into the deep end of the gauge channel.
将刮板放置在水平的平面上，用小调漆刀将待测样品搅拌均匀，然后在沟槽最深部分滴入试样数滴，以能充满沟槽而略有余为好。
