Rz

微观不平度十点高度：在取样长度内5个最大的轮廓峰高的平均值与5个最大的轮廓谷深的平均值之和

Results (measured values) are calculated as mean values from 5 consecutive measurements

Ra

轮廓算术平均偏差：在取样长度L内轮廓偏距绝对值的算术平均值

The arithmetic average of the absolute values of the roughness profile ordinates

Rt

轮廓最大高度：在取样长度L内轮廓峰顶线和轮廓谷底线之间的距离

Maximum roughness, the distance between the highest peak and the lowest valley within the evaluation length
