Data of quantitative XRD-analysis for crystal phases in GNB are presented in Figure 1.
Even though these reflections were not part of the test object, in order to provide a higher quality of XRD-analysis, this data was included in the calculation of crystal components concentrations (by wt. %) in GNB.

Data necessary for identification were collected basing on measurements of free vibrations of a three-layered cantilever beam at a special laboratory stand.
It was shown that the vibration reduction capabilities of MR adaptive structures are significant.
Essential data for performing the identification were data basing on the measurements of displacement of the beam free end.
Obtained data and assumed model of the beam were used in the identification of MR fluid (type 122-2ED) complex shear modulus.

The test results were measured on profilograph and were obtained the following data: the width of the grooves wear was 936 microns with burnishing and 1152 microns with polishing, depth was 2.16 and 4.94 microns respectively.
The test results were measured on profilograph mod. 252 and were obtained the following data: the width of the grooves wear was 936 microns with burnishing and 1152 microns with polishing, depth was 2.16 and 4.94 microns respectively.
The vertical position of the shaft contributes to wear of the shaft connected with the fact that the sealing area gather the wear product generated during operation of gears and bearings in the reduction gearbox, gearbox and spindle heads.
Unfortunately, due to the confidentiality agreement it is impossible to bring the absolute values, but the relative value of these defects: front - 42%, rear - 58% (the given data based on the defects statistics for a 5 year period, due to the technological modernization of production lines it is inappropriate to carry out the analysis on the basis of 10 years of statistics).

Even when the data of regenerated energy by two motors was compared with that through gears (ig=1.0), 35.4% of improvement was obtained at the condition where the maximum improvement was obtained by two.
Nmm(t), Nsm(t), K, ifg, ic(t) denote the number of revolutions of SM and MM, the back electromotive force coefficient, the final reduction gear ratio and speed ratio of CVT, respectively.
Even when the data of regenerated energy by two motors was compared with that through gears (ig=1.0), 35.4% of improvement was obtained at the condition where the maximum improvement was obtained by two motors as shown in the figure.

According to the actual situations of our country, the study processes Radiation model parameters and simulates internal migration in Beijing based on the socio-economic data(2005-2010).
[J]Journal of Tongji University,2002.30(9):1056-1060 ], it is also very difficult to obtain accurate movements data.
The population density is one of the effective ways to measure the spatial population distribution ,the data of population density is relatively easy to get.
In China, scholars believe the census data is the most direct and reliable data on the study of spatial distribution of population, and the smaller the statistical unit is, the more it may reflect changes in population density detailed features[[] Han Jiafu, Zhang Zhong, Qi Qingwen.
On the basis of 1st Economic Census Data[[] Beijing Economic Census Data. http://www.bjstats.gov.cn/jjpcsj/index.htm ] (2005) and District/County’s Data[[] Beijing District/County’s Data. http://www.bjstats.gov.cn/qynj/2010-qynj/system/main2.htm ] in 2009, GDP of all the areas in Beijing is obtained.

According to data about GIS breakdown maintenance in Maintenance Branch of State Grid Chongqing Electric Power Company during recent years, GIS accident of Chongqing Electric Power Company that happens every year is internal fault of local air chambers (such as breaker, PT and bus) in most cases.
As a result, bad consequences like corrosion and reduction of insulating property will be caused.

On basis of the data and analysis, two conclusions are drawn: (1) Installation of baffles exerts high influence on heat transfer characteristics of the heat exchanger studied. (2) The reason why the baffles could exert such influence is that the baffles prevent much air from flowing into external zones of the baffles, so in per unit time more air exchanges heat energy with hot walls of heat exchange tubes, which are in internal zones of the baffles.

All the experiments of CuNPs-Pl synthesis and optimization were performed in triplicate run whereas antimicrobial and antioxidant assays were experimented in five runs and data was statistically expressed as mean ± S.E.
It is believed that the reduction process is increased as the volume of extract increases which is responsible for fast nucleation resulting in the small size nanoparticles.
Several functional groups have been revealed in the FTIR spectral data of PlL and CuNPs-Pl as shown in Fig. 4 (A).
DPPH assay principle involves in the reduction of DPPH radical to DPPH-H non radical form which indicates from the color change from purple to yellow.

The histogram results also demonstrate that the Co3O4-NPs possess a relatively larger average particle size compared to the crystallite size estimated from the XRD data.
For further elucidation, the experimental data were fitted by a pseudo first-order kinetic model using the equation, ln(At/A0) = -kt, where At and A0 represent the absorbance of MO dye at time t and at the initial state, respectively, and k is the rate constant of the reduction reaction [57, 58].
