Keywords: model test stand, laser measuring equipment, processing of experimental data, flow, flow velocity, turbulence, the velocity profile Abstract.
However, the process of obtaining the reliable data by means of calculations must be verified by physical modeling using modern methods of flow visualization on special research dynamic stands.
Its use is intended for the development of a uniform seed flow of reflecting particles (tracers) in the measurement and reduction of fuel expensive material tracers.
In this regard, the data given in this article are new, and we should expand our research relating to the study of counter eddy flows in a particular multilayer.

The data on diffusion in undoped oxides at low temperatures is also of considerable interest.
The experimental data (Fig. 1, curve 1) for nanostructured powder of LaMnO3+δ oxide is consistent with expression (1).
According to our data, this assumption was valid only for nanoscale oxide powders obtained by mechanical activation.
High-temperature data for NdMnO3+d and SmMnO3+d are absent, but probably they obey the same law.
However, the reduction proceeds at high temperatures.

Compared with metal and ceramic materials, composite materials have great advantages in vibration and noise reduction; therefore composite gears can be widely used on occasions where low vibration and noise are demanded.
The collected signals mainly include two sets of data: 1) The 1/3 octave spectrum of noise signals.
The results analysis Based on the band sound pressure level data of the blocks without and with microcapsules obtained at different temperatures, their noise signal spectrums are drawn.
What’s more, based on the A weighted data of the two groups of samples at different temperatures, the A weighted sound pressure level contrast diagram of the two sets of gear material specimen can be drawn.
Friction noise and noise reduction technology research [D]. ​​

Through applying the corrections on the axis Z, B and Y, we seek the reduction of the deviation of the axial profile as compared to the Archimedes one, chose as a reference.
We can observe the reduction of the maximum deviations to the level of 0.003 mm, when the eccentricity is 1.8 mm.
Table 2 represents the working data regime for the finishing of the worm flank presented in paragraph 4, using EMUGE-FRANKEN solid carbide mill [8, pg. 54].

eS RA N E S + − = 100 100 ln 4 (1) Where E denotes the elastic modulus, RA means the reduction of an area, Se is the failure limit.
In terms of the reduction of an area, it was measured from the failed tensile specimen after being tested at 350 o C, which was 24.8%.
When incorporating the above data, the O'Donnell and Langer relationship for the zirconium cladding tube during cyclic pressurization can be proposed like the following formula; 6.341 7.5288 += N S (3) When the formula was collated into the data in Fig. 2, the O'Donnell and Langer relationship fitted well into the Zircaloy-4 fatigue data, which revealed that zirconium cladding satisfies the fatigue relationship proposed by O'Donnell and Langer when it was repeatedly deformed at the frequency of 1Hz.

Data collected from plants showed that wastewater enrich acrylic acid, acrolein and hydroquinone and the odor of wastewater is very unpleasant.
The reduction in the rate constant is due to the reduction in the penetration of light with surplus amount of TiO2.
The data for acrylic acid removal are shown in Fig 5.
All correlation coefficients were higher than 0.98, indicating that the proposed kinetic model was in good agreement with our experimental data.

Introduction Since occurrence of casting defects results in the reduction in casting yield, reducing occurrence of casting defects is important.
We classified casting defects according to occurrence factors and summarized the results for use as standard analysis data.
We then prepared standard data from the results of this analysis.
As a result, we have facilitated identification of occurrence causes, as well as establishment of countermeasures and their control, and have enabled reduction in rate of casting defect occurrence.
The authors intend to standardize analysis procedures through accumulation of further data and to construct an expert system.

Primary and secondary optics strongly differ between out-of-plane (coplanar geometry) and in-plane (non-coplanar geometry) configuration due to a weak diffracted signal recorded in in-plane configurations as a small material volume is sampled (x-ray depth penetration limited to some tenth nanometers at grazing incident angle of 0.2°), requiring only a system of long soller slits for divergence reduction.
From the values reported in the table it is suggested that the in-plane tensile stress is a bit higher for the thinner film indicating a reduction in the stored stress when thicker 3C-SiC films are considered, consistently with what found in ref. [5].
This value is lower than the 5.05 × 10-6 K-1 at 800 K reported by Slack et al. [6] This difference can be justified by considering that data considered in their work were taken on polycrystalline brick of mixed SiC polytypes while, in the present work, data were taken by considering a single crystal 3C-SiC film grown hetero-epitaxially on a Si substrate.
In this paper, we have shown a preliminary study about the effect of thermal treatments on 3C-SiC lattice, with measurements of the three parameters a, b and c by means of XRD. (331) skew symmetric reflection was chosen to confirm on a larger sampled volume the data obtained by in-plane XRD measurements, being the resulting values in perfect agreement.

Introduction The presenting reduction of the ozone layer leads a greater ultraviolet (UV) radiation impacting human health unavoidable.
Data was expressed as means ± standard deviation (SD) and analyzed by Wilcoxon signed ranks test that P < 0.05 was significant.
The reduction of pH might cause by oxidation of jojoba oil [5] and degradation of aloe vera as that of foundation 2 was not differed (data not shown).
In addition, other SPF booster may be applicable as the stability of the foundation without aloe vera (formula 2) was the best (data not shown).
