2) arithmetical average roughness height (AARH)
算术平均粗糙高度
3) profile roughness tester
粗糙度轮廓度仪
5) roughness average
算术平均偏差
1.
The testing to standard examples of surface roughness is carried out with the non-tactile MicroXAM surface profiler made by ADE Phase-Shift and the rules of 3D roughness average and root mean square are analyzed according to the testing results.
使用ADE公司的非接触式表面三维形貌仪对粗糙度标准样板进行系统测试,依据测试结果分析了三维粗糙度参数算术平均偏差与均方根偏差的规律。
6) arithmetical average deviation
算术平均偏差值
