The surface roughness (Rz) is a ten-point average roughness.
The back (100a) of the substrate of the InGaAs laser is processed into an optically irregularly reflecting face having a continuous irregularity the surface roughness (Rq: root mean square roughness) of which is 100 nm.
The surface roughness Ra(b) and the surface roughness Ra(i) are arithmetical mean roughness values and are surface roughness parameters determined in accordance with a Germany standard "DIN-4768".
The preliminary average surface roughness is less than the final average surface roughness.
The second surface roughness value is lower than the first surface roughness value.

The texture of an element provides information.
Check the quality of the keratin (colour, texture, roughness, irregularities, etc).
A 10-point rugosity scale was developed, using 10 different textures.
After 2 hours: Rough skin texture is decreased by 11%.
The textured surface can be textured by way of an imprinted pattern or by roughening, and can be extruded.
The nanoparticles may serve as catalysts for activation rugosity of mesoporous carbons.
The nanoparticles may serve as catalysts for activation rugosity of mesoporous carbon blacks.
These factors will also be influenced by the shape of the fragments and the rugosity of the surface.
The Ra parameter indicates the rugosity and is attained as an average level of rugosity, considering the absolute value, along a period of time defined as L (figure 4.2).
The invention relates to a method for reducing the rugosity of the free surface of a slice of semiconductor material.
Vehicle transfer function for wheel and bogie emission
Surface coarseness of the workpiece surface is determined on the basis of the relative roughness relationship described above.
The resultant surface has both nanoscale roughness and microscale roughness.
The roughness of the second layer corresponds to the roughness of the first layer, where the first layer has a roughness greater than or equal to about 20 Å root mean square (RMS).
1/3 octave band roughness level, dB
The roughening can occur in two steps.
Roughness of tissue is characterized by Average Primary Amplitude and Average Peak to Valley Waviness.
The roughness of the slide surface of the shaft is preferably 0.2 μm or greater in arithmetic average roughness.
The second rolling contact surface has a second RMS roughness Rq2 and has a second roughness pattern y2.
The RMS roughness value of the second surface can be greater than the RMS value of the first surface.
Wheel and rail roughness
First portions (41) of the wall provide the outer surface (23) with a finish having a first roughness while second portions (43) of the wall provide the outer surface with a finish having a second roughness different than the first roughness.
Layer A has a SRa roughness of from 1 nm to 5 nm and a SRz roughness of from 10 nm to 100 nm.
Layer B has a SRa roughness of from 5 nm to 50 nm and a SRz roughness of from 10 nm to 200 nm.
Upon the performing of the plurality of ion exposure cycles the mid frequency and low frequency linewidth roughness are reduced.
