Introducing abrasive grains of different numbers (size) intensifies the material removal but it also affects the quality of the lapped surface.
The probability of breaking the grains up increases with the increase in the micrograin size, under the constant load and abrasive particles concentration.
In order to ensure the one-layer distribution of the large number micrograins it is necessary to reduce the abrasive particles concentration on the active surface of the lap and in turn abrasive particles crushed under the higher unit pressure and the material removal rate decreases.

Introduction Grinding can be described as a multitooth operation in which a number of abrasive grains held by a bonding material perform the cutting operation [1].
Some portion of this grinding energy is spent for chip formation, but most of the energy spent is consumed in sliding friction against dulled flattened abrasive grains and the work surface without removing any material.
Here the total number of treatment (N) is 8, number of central point (Cp) is 4 and number of variable (n) is 2.

In table 1, the number in the square brackets indicates the atomic N/Al ratio.
The average ferrite grain size was 5.2 ± 0.06 mm, and the influence of the composition and the isothermal hold temperature on the grain size was not pronounced Numerical analysis of the IF spectra.
In order to resolve the Snoek spectra of Fe-Mn-N alloys into a number of Debye relaxation peaks, a three-dimensional arrangement of the Mn substitutional atoms was taken into account.
In this notation the number indicates the number of Mn atoms in the octahedral unit.

The energy of the acoustic emission events is relatively concentrative and the number of the acoustic emission events is less before and after the main damage; the acoustic emission events and their energy of limestone “break out” very suddenly and concentrative, almost no acoustic emission event occurs before and after
The number of acoustic emission events is still large and their energy rate is still higher at this time.
With further loading, coal gradually comes to the state of residual strength or deformation stage and the number of the acoustic emission events decreases gradually and their energy rate reduces gradually.
A large number of microscopic studies show that coal is a typical inhomogeneous material.
It consists of sand grains and fillings among the sand grains.

Introduction Decontamination of spent ion-exchange resins (SIER) formed at the nuclear power plants (NPP) inevitably leads to using alkaline solutions to treat the surface and the bulk of resin’s grains to decompose the acid-insoluble silicates with the cesium ions being irreversibly bound by them [1, 2].
Cs-137 extraction from neutralized eluate was performed in dynamic conditions using a column filled with a TERMOXID-35 sorbent, which is a composite spherically-grained material based on nickel ferrocyanide applied onto hydrated zirconia (TERMOXID, Russia, TU 6200-305-123422660-98 (technical conditions)) [15].
%Sorption=(1-AiA0)×100 (1) %Desorption=1i(Vki×Aki)Ac×100 (2) where Ai – filtrate’s activity (Bq/mL), A0 – starting activity of the solution (Bq/mL), Aс – activity of RFR (Bq), Aк – activity of eluate (Bq/mL), Vk – eluate’s volume (mL), i – ordinal number of eluates fraction.
Cs-137 sorption efficiency from deactivating solution increases with the number of sorption cycles that is apparently related to gradual entering the operating mode by the resin.

The rock was grinded into the grains of mean diameters size from 10 to 50 microns and warm up till 800°C due to remove the water from the particles of stone.
The basic stereological parameters like: volume fraction (Vv), number of particles per volume unit, mean particle volume, particle volume dispersion, shape factor were indicated [9].
If we compare the results of number of particles per volume unit to different fraction of Tuf it can be observed that for higher fraction of filler there is lower number of particles (Fig. 7).
Number of particles per volume unite for different fraction of Tuf.
The morphological investigations shown that particles of Tuf coagulates – increasing addition of Tuf caused increasing mean volume of the particle and lower number of particles per volume unit.

Micro erosion is found on the surface of turbine components where fine particles with grains size less than 60 μm are moving at very high velocity.

The effect parameters like filament radius (r), filament number (N), filament-substrate separate (H), and the distance between the filaments (D) have a profound effect on substrate temperature, which influence both the growth rate and the quality of the films [2].The effect of these parameters are optimized separately by varying one of the four variables while holding others as constant so as to improve substrate temperature uniformity.
Finally, the number of filaments is examined (Fig. 2(d)).
The temperature profiles for 2 and 7 filaments indicates that the temperature uniformity is significantly improved when the filament number, N, is increased.
Thus a better way to enlarge the growth areas of the diamond films is to increase the number of filaments.
Apparently, the thin film is fine and close in texture, and the diamond crystals are well-faceted with grain size of 2-5μm at position 1 or 2.

Application of Scatter Grain Cross in Multi-phase Transmission Planning.

Nevertheless a number of works show discrepancies in the temperatures and even in the type of magnetic reorientation transitions [6-8].
This procedure was chosen in order to provide favorable conditions for growing large enough single crystalline grains.
The average RE-Fe exchange interaction energy is reduced, because the number of Fe nearest neighbors decreases with the increase of x, and as a consequence, the Curie temperature of the RFe9Ti single crystals is usually lower than the TC of RFe11Ti single crystals by 12-15K.
