Slight roughness

A greyish, slightly rough, matt surface that is carved suggests bog oak (Fig. 2.5). 

Plastic coated bead simulant Very regular Not gritty, but looks slightly rough. Possible surface peeling Signs of surface chipping... 

Figure 12.19 indicated that unlike the Pt case, the Ir/diamond interface was only slightly rough, i.e. there were protuberances of Ir that were approximately... 

Fig. 3 Schematic representation of a slight (a) and a strong (b) roughness. The profile of slight roughness is described hy the fimction z = L is the effective thickness of the porous film that represents strong roughness. (From [27])...

For slightly rough surfaces, the problem was solved in the framework of perturbation theory with respect to the parameters V (i ) 1 and h/S 1,... 

Line 5 in Fig. 5 is calculated for a surface having slight roughness, according to Eq. 34 and 39. The hydrodynamic roughness factor R is chosen so that this line connects the origin with the experimental point for the highest value of 5. This yielded a value of K = 1.3. 

Fig. 5 Dependence of the parameter AF/pf on the velocity decay length points experimental data, line 1 in both plots indicates an ideally smooth surface, a Influence of strong roughness according to Eq. 44 for different values of -2 69, 3 172, 4 276 nm) and L = 506 nm. b The same for different values of L 2 460, 3 506, 4 690 nm and fn = 172 nm. Line 5 in both plots was calculated for slight roughness (roughness factor R = 1.3, Eqs. 34 and 39). (From [27])...

Figure 9. Borehole temperature versus depth (Cuffey and Clow 1997), and 5 0 of ice versus age (Grootes and Stuiver 1997), for GISP2, central Greenland. Approximate correspondence between the imprints of prominent climate events in these records are indicated by tie lines the diffusive information loss from heat flow is evident in the greater smoothness of the borehole-temperature record. The borehole record is quite smooth, but appears slightly rough because of the plotting package used.
