Dedicated tools were also developed to further post-process the recorded data.
Saved throughput data are then used for the post-processing.
By using this method speed fluctuations were removed from accumulated data.
Here the amplitude of vibration is clearly magnified with respect to the reference data.
All measured data are strongly dependent on direction of small wind turbine bed plane.

The data shows what level of surface roughness is achieved when choosing different cutting conditions.
For sample no. 6 there was a reduction in oscillation speed, which resulted in a larger removal of material.
By increasing the feed rate of the grinding wheel (10x, 50x, 100x, 100x reduction oscillation speed), it was clearly visible that there was an increased roughness of the surface with a maximum value Ra 0.352 µm (sample no. 6).
In a ratio of values of the Ra and Rz parameters there was a reduction or increase in values of approximately 5 %.
Sample no. 6 with the feed rate of 0.254 mm.min-1 and the reduction of the oscillation speed by half did not suit the desired parameter Ra to 0.3 µm.

Alkali treatment also helped eliminate the non-cellulosic constituents via reduction in the 1240 and 1750 cm-1 peak.
The FTIR spectrum of the acid-hydrolyzed fibers was similar to those treated with NaOH (data not shown).
The untreated fibers appeared as large clumps without noticeable bundles or fibers (data not shown).
An aqueous dispersion of cellulose was obtained after acid treatment, signifying stabilization due to surface anionic charge [2] and significant size reduction of the alkali-treated fibers.

But with the use of calcined hongurin there is a slight decrease in the water resistance of the rock: in the optimal composition from 0,96 to 0,87, it is explained by the decrease in the activity of hongurin due to the reduction in the number of active groups, and the resulting new centers have a Lewis character.

As a result of mathematical processing of experimental data the equations of dependence on variable factors were received: Normal density: Y1 = 48,11 – 1,17X12 – 8,00X22 + 3,33X1 + 3,33X2 + 1,88X1X2; (1) Bending strength of samples: Y2 = 0,52 + 0,1Х12 + 0,08Х22 – 0,01Х1 + 0,1Х2 + 0,04Х1Х2; (2) Compression strength of samples: Y3 = 15,62 – 0,73Х1 + 2,5Х2 – 4,47Х12 – 1,5Х22 – 1,53Х1Х2; (3) Sample softening factors: Y4 = 0,81 – 0,11Х1 + 0,01Х2 + 0,08Х12 - 0,04Х22 + 0,02Х1Х2
Calcination of hongurin at a higher temperature (360 ° C) was determined to cause further reduction of the strength of the samples.

Due to the presence of ferrous ion, nickel reduction is inhibited while iron deposition rate is enhanced when compared to their respective deposition rates in single metal plating baths.
In the earlier studies, the anomalous behavior was assumed due to precipitation of iron hydroxide on electrode surface that it was inhibited nickel reduction, instead of iron reduction.
Ni-20%Fe deposit has a lowest remanence and the coercivity show a monotonic decrease with increasing the Fe content in deposit.The test data indicate that the Ni-Fe deposit has a satisfactory magnetism property.

This data is consistent with the reference[7] and is reliable.
So the reduction of the number of the GB can lead to the reduction of the energy of the interconnect system.
As the result of the reduction of the number of GB, which is an important EM diffusion path, the EM diffusion is restrained.

Porosity reduction of cements can be accomplished by reducing the water demand of the system or by compaction.
Two main features are to be noted, firstly the agreement between the density measured by pycnometry and that calculated from phase composition is generally very good, (< 3%) providing independent verification of the phase analysis data and secondly density appeared to increase with compaction pressure, suggesting that the amount of unreacted ßTCP, (� = 3.0 g cm-3) was higher in the compacted material.
At compaction pressures of between 10-25 MPa, although the reduction in the porosity was ~10% this did not result in a marked increase in compressive strength possibly due to the lower degree of reaction (Fig.2).
Such dramatic gains were not noted following the compaction of this cement system; this is probably due to the reduction in the extent of reaction with an increase in compaction pressure.

At home and abroad, experts and scholars have done a lot of work in the single-bent industrial factories, but there are few theoretical achievements in thses multi-layer frame-bent structure industrial factories, especially in the analysis of energy dissipation and seismic reduction.
Therefore, study of the energy dissipation and seismic reduction to the new multi-layer frame-bent structure of industrial factories has important practical significance.
The S shaped steel damper is a new kind of seismic reduction device, which can absorb the earthquake energy by plastic deformation to protect the main structure.
The paper only extracts some parts of the results, due to a great quantity of the datum.
And the other datum also has the similar conclusions.

Introduction With the rapid development of information technology, the miniaturization of electromagnetic devices, the reduction of the power, the improvement of the reliability and the increasing of data transmission rate become the inevitable trend of development.
In addition, it is well-known that eddy current losses give rise to a reduction of the permeability, which can significantly effect the efficiency of electromagnetic devices [4,6].
With the increase of Al2O3 chips n, diffraction peak is gradually widen, indicating a reduction of the grain size of the films.
