The maxima heights decreased to 6 times with respect to the silver microphases, which is caused by the presence of a reducing agent, and is consistent with the literature data [16].
Thus there is a fold decrease of the maxima heights silver nanophases compared with silver microphases, which may be caused by the formation of the different monolayers of silver oxide as a result the chemical reduction and is consistent with the literature data [16].
This reduction of maxima heights can be associated with the formation of silver oxide monolayers in the different oxidation in the presence of large amounts a reducing agent and is consistent with the literature data [16].
These facts may be explained by the presence of an excess of a reducing agent than silver nanophases obtained in equal molar ratio of reactant which in agreement with literature data [16].
These facts may be caused to the presence of an excess of a reducing agentt which in agreement with literature data [16].

This approach will produce large amounts of measurement data, some data in the cross section, some data is not in the cross section, and even some of the data deviated from the cross section too far to become invalid data.
Field data collection methods and data formats and graphical analysis The field data was collected using the 8-shaped data sampling method, shown in Fig. 1.
The difference between the design cross-section data and actual cross-section data.
Furthermore, in considering the valid data operator is visible in the process of data reduction, which is the problem of visualization.
While the data, away from the section, not in the buffer_data1, is the invalid data.

Best results were obtained with four passes followed by 70% cold rolling reduction.
More precise data are summarized in Table 1, and the main comments which can be made on the tensile behavior are the following: (i) SPD caused a drastic reduction in W-H capacity, a feature reflected by a reduction of uniform deformation, which came down from 13.4% for the annealed bar to ≈ 3% for 1XH and 4XH.
On the other hand, total elongation was not much affected, compare data of Table 2.
Summary of tensile data, plus W-H exponent Samples sy (MPa) su (MPa) eun (%) et (%) n 0X 337 481 15.0 30 0.136 1X 561 589 3.1 11 0.027 1XH 544 573 3.9 22 0.045 4XH 651 682 3.7 22 0.041 1XH+CR(70) 747 769 3.4 19 0.029 4XH+CR(70) 779 877 3.3 18 0.043 CR(30) 538 633 2.9 18 0.087 CR(70) 605 702 2.4 12 0.093 CR(90) 697 797 3.0 12 0.058 Again on the subject of cold/warm ECAP, data shows that room temperature deformation (1X) gives little strength benefit over 1XH, whilst total elongation is halved and εun is also slightly reduced.
Recalling that Ti is a difficult material to process and that warm ECAP is a practical solution, thermal stability data are useful to plan fabrication, anneal and operational temperatures.

Au nanoparticles of about 5 nm were deposited on the surface of TiO2-NTs with hydrothermal reduction method.
However, TiO2-NT (Au) for Cd2+ reduction is reported uncommonly.
Hydrothermal reduction method was the method used to load Au onto the TiO2-NT support.
The catalytic properties of obtained samples were tested by reduction of Cd2+ ions.
All these facts are also confirmed by data from Tab.1 Fig.3 Adsorption patterns of different samples Fig.4 shows XPS patterns of TiO2-NTs (Au) composite system after reducing experiment under UV-light.

Ti(C,N) powder was prepared via carbothermal reduction nitridation (CRN) using rutile and carbon black as the raw material.
The lattice parameter (a) of Ti(C,N) can be determined by the interplanar crystal spacing (d) and the corresponding crystal indices (h k l) on the basis of the XRD data.

Comparative study of various data conversion methods for torsion tests applied to a HSLA steel J.
Conversion of torsion data The conversion of torsion data to true stress, true strain and strain rate was conducted by means of the methods described previously.
The open circles are the experimental data and the lines correspond to predictions of Eq. 11.
The open circles are the experimental data and the lines represent the fit obtained by Eq. 11.
A good correlation is obtained indicating the quality of the data reduction process.

Under this content, MSP has an outstanding friction reduction and self-repairing properties
With load increased, the friction coefficient also increased, but the data were less than 0.10, which indicated that friction pair had been in a mixed lubrication state.
All that illuminated that MSP in lubricant oil had a good friction reduction property under variable testing loads.
Based on these above data, MSP in lubricant oils can also make friction pairs representing a good anti-wear performance.
(2) Under the conditions of variable loads, MSP has a good friction reduction and anti-wear effect.

And it is a data mining method that shows clearly and objectively the knowledge provided by reduction of the massive, complex data under the condition of keeping the classification property invariant.
Different projective direction reflect different data structural characteristics, optimum projective direction should be the projective direction which can reveal some eigenstrure of high - dimensional data probably.
Dispose data discretization, prepare the data, and generate the data processed discrete information table.
It is noteworthy that, for the application of RST, data processing is very important.

Finally, X-ray diffraction (XRD) data were obtained with a Rigaku DMAX III-C diffractometer in order to analyze the structural evolution of the annealed films.
The data show that the samples are already nanocrystalline when deposited, presenting a monoclinic structure as can be deduced from the diffraction peaks position.
The reduction of the hysteresis from 0.60V to 0.18V is assumed to be related with a reduction on the oxide trapped charges.
Figure 2 - C-V data for samples: a) as-deposited, b) 2 h annealed, c) 5 h annealed and d) 10 h annealed.
The data achieved show that annealing the films for 2 or 5 hours will improve the film's density, not causing detectable structural changes.
