How can you use “roughness” in a sentence? Here are some example sentences to help you improve your vocabulary:
These roughness values were primarily based on wave shaped surface where the distance between the peaks was around 200 μm and where the main peak-to-main valley distance was around 20 μm (Figure 5).
To verify the surface roughness values, the finished die surfaces were recorded with a profilometer (Federal Surfanalyzer System 5000, Federal Products Co, Providence, RI).
Thirty-six metal dies were machined out of carbon steel to dimensions shown in Figure 1. During the machining procedure all the surfaces to which the zinc phosphate cement would be attached were finished to roughness values around 6.3 μm.
A texture measure was developed, based on a gradient-filtered image, as an indicator of fine spatial changes in the cytoplasm [ 36 ] . The cytoplasm of control livers had a smooth and uniform appearance, compared to that of treated animals, which exhibits more roughness, mainly caused by vacuoles.
The profilometer readings of the metal die surfaces gave an average surface roughness value (R a ) of 5.49 ± 0.98 μm.
