However, there are not any thermodynamic data of the reaction of the hydrogen interaction with Ce6Ni1.67Si3 in the scientific literature until now.
Results and discussion According to the X-ray diffraction data the synthesized Ce6Ni1.67Si3 sample had the hexagonal structure, space group P63/m, with the unit cell parameters close to those reported previously [3, 4].
Crystallografic data for the Ce6Ni1.67Si3 compound and its hydrides.
According to the X-ray diffraction data the sample under investigation did not decompose after partial desorption i.e. it remained the hexagonal structure P63/m of the original sample but the lattice parameters changed slightly.
On basis of the obtained data it could draw a conclusion that in the range of the hydrogen concentration in the IMC 10.0< C <11.2 the enthalpy values for the absorption and desorption processes coincide in magnitude.

Results and discussion The minimum-energy configurations of pure anatase TiO2 obtained by GGA and GGA+U methods in our study were compared with experimental data [14] as shown in Table 1.
It showed that the agreement between GGA method results and experiment data is better for the structural parameters than ones of GGA+U method.
For Ce-doped TiO2, Fig. 2b shows that the VBM consists mainly of O 2p and Ce 4f states, whereas the CBM has Ti 3d and Ce 4f states, the impurity states change the construction of band, and thus led to a band gap reduction by about 0.29 eV, which would be expected to lead to but a little enhancement in photocatalytic efficiency.

According to data from [11] Friedel’s salts at high pH are stable and only if pH is lowering (for example, due to concrete matrix carbonization) their solubility becomes higher.
According to the data in [6; 12], CN is bound in stable CHNA С3А´Са(NО3)2´10Н2О, morphologically similar to CHSA of the monosulfate form and CHChA.
The analysis of published data allows us to state the absence of an unambiguous solution regarding how to define the amount and conditions of the guaranteed binding of calcium chloride and calcium nitrate in poorly-soluble hydrated cement products.
The input data for thermodynamic calculation are given in Table 2.
(7) Considering the known data on the partial pressure of CO2 which corresponds to its content in the atmosphere and the data on possible concentration of chloride ions and nitrate ions within the range from zero to the calcium chloride and calcium nitrate solubility the stability fields of these salts at the partial pressure СО2 3.97×10–4 were obtained (Fig. 1).

Both twinning and strain induced phases transformations are impeded by grain size reduction [4, 5].
The resulting tensile data has been differentiated numerically by means of a piecewise polynomial fitting to obtain the work hardening rate.
A good fit to the experimental data was found when m was taken to be linearly dependent on 1/ √D.
Fig. 5 illustrates the results of nonlinear programming used to obtain an optimal set of parameters for matching the experimental data (Fig. 2).
An implementation of a Kocks-Estrin-Mecking model incorporating twinning, previously developed by Bouaziz and Guelton [6] was applied to this system giving a good fit to the experimental work hardening data (beyond yield).

Vertical collision have some experimental data, you can do some kind of analogy analysis[7].
However, the oblique impact has little experimental data, validation of the theory and practice are not fully[8].
Establishment of Procedural framework By obtaining all parameters users input, each parameter is converted to a float data type, define the double type v (v1, v2) on behalf of the speed values to be drawn, use the equation for the speed of c # syntax to build, cars and car rear-end collision types, for example, The typical traffic accident patterns in the technical identification of vehicle speed gives the following formula: (4) (5) Using the appropriate equation for the C# function to build the C# statement is: (6) (7) Secondly, displaying the calculation result, unless the parameter input values, results are not displayed and vice versa if the all parameter values have been entered, then the speed values of double type are v (v1, v2) converted to a float type and keep only two decimal places, and then directly label to display the value of the label, the corresponding C# statements is: label31.Text = "" + ((float)((int)(v1

By combining frequency data with growth characteristics (rhizomatous, stoloniferous or bunchgrass), warm or cool season grass, and habitat preferences, the species most frequently found across counties and recorded in the widest range of habitats were selected.
This reduction of mixtures evaluated was due to the fact that the RY species, big galleta (Pleuraphis rigida), was eliminated from the study after preliminary tests revealed poor germination.
Monthly settings for each growth chamber were determined by calculating the mean minimum and maximum temperature and mean relative humidity data from historical data obtained from the Western Regional Climate Center for weather stations within each respective ecoregion.
Where significant differences existed, data from the differing ecoregion(s) were separated.
Data from all other ecoregions were combined.

Yu studied the mechanism of data sharing in such system by using XML [5].
Description of Data.
As a specific kind of application of C/S architecture, B/S architecture is made up of browser, server and database, which allows application program for user separate from code of operation logic and figuring data by introducing a group of operation objects.
Thus user is only responsible for showing the final data, having nothing to do with all other complexity hidden behind operation objects [7].

When n is assigned, both the bulge height and wall thickness reduction decrease with K increasing.
Then the K and n values are achieved by the experimental data from the tensile test.
In addition, the width of weld and HAZ cannot be measured accurately, so the microhardness test and data solving can cause error.
The results had demonstrated that the deformation data were favorable for high accuracy of this approach.
The data from THF are more accurate than that from tensile test since the data are under actual stress state.
