As follows from the obtained data, in zone (II), with CaO content increase from 25 to 35 %, the activation energy of a viscous flow decreases, and at 45% it increases.
Obtained data are quantitatively some differ from the results reported in the literature [3].
The results obtained describe qualitatively melts structure in the same way as the known data.

Introduction Adhesive-bonding for the unions in multi-component structures is a choice to consider over welding, riveting and fastening, due to issues such as the reduction of stress concentrations, reduced weight penalty and easy manufacturing/automation [1].
The correlation of a with the P-d data, allowing the calculation of GIc, was made possible by the elapsed time from the beginning of the test, which is easily and accurately related to the P-d data (by the testing velocity) and a (by the shooting time interval).
Evaluation of GIc The most common data reduction schemes to derive GIc of structural adhesives from fracture characterization tests rely on Linear-Elastic Fracture Mechanics (LEFM) principles [9].
Particular attention was paid to the determination of GIc, carried out by two different reduction methods (CCM and CBT), whose results matched quite well.

Especially for complicated vertical buildings, using three-dimensional mode program can easily input the data.
(2) Graphic file is data document.
It is different from other domestic structural programs which only can convert graphic into data file.
EAABS allows reducing rigid zone size, and the reduction includes 0% OFFSET, 25% OFFSET, 50% OFFSSRT, 75% OFFSET and 100% OFFSET. 0%OFFSET means that there is no reduction, the calculation length is the longest and  the centerline of structural member force is calculated. 100% OFFSET means that there is reduction, the calculation length is the shortest, and bearing pad side of structural member force is calculated

However, when the adsorbed Pb and Cu in the binary solution was compared to their corresponding amounts in single-metal solutions, an average of 9% reduction was observed for Pb, while an average of 4.1% increment was observed for Cu (Fig. 2B).
The relative reduction in Pb adsorption during competition (in the binary solution) as opposed to relative increment inCu adsorption signifies that the coexistence of Pb with Cu affectedPb negatively, but Cu adsorption rather increased relatively in the midst of competition posed by Pb.
The adsorption data was fitted into the Langmuir and Freundlich isotherm models, and the parameters are listed in Table 1.
Data for metals in the binary solution fitted the Freundlich model better (R2= 0.9982 and 0.9959 for Cu and Pb, respectively) than that in the single-metal solution, and even better than the Langmuir model for all solutions.
Adsorption data of Pb and Cu fitted both Langmuir and Freundlich isotherms well with equally good linearity When Pb competed with Cu in binary solution, Pb recorded greater bonding energy (about 2.5 times more) than Cu,and seemed a possible further explanation to why the relative proportion of adsorbed Pb increased, while that of Cu decreased by same extent.

The variations of rotor tip load along with the axial direction were discussed with the reduction of flowrate.
Detailed design data is shown in Table 1.
Measured total and static pressure data were applied to calculate the average total pressure and static pressure of each section.
In addition, The computed blockage coefficient or flowrate reserve coefficient based on measured boundary layer data has a great contribution to the promotion of compressor design capability

In 2009 China's Ministry of Housing launched a official document "Assessment Framework on Carbon-reduction of China’s Lowcarbon Green Residential Communities" and created the concept of "low-carbon residential communities " from policy aspect initially.
The planners use quantitative data to reflect carbon CO2 emissions in the process of construction and management of residential communities.
It can maximize the energy efficiency and reduce the use of fossil energy by assessing and controlling the data.
Secondly, many laws and regulations also lack indicator system that can provide clear quantitative data for carbon emission.
Meanwhile planners should reduce earthwork excavation to ensure that the volume rate and building density of construction projects are not higher than the requirements from "Assessment Framework on Carbon-reduction of China’s Lowcarbon Green Residential Communities " while the green rate is not less than the requirements.

The main functions of visualization feedback analysis system of multi-message of tunnel are follows. 1) Monitoring the observing data by database, with the functions of insert new record, delete record, save data and searching certain records. 2) Can rapidly identify the mechanical parameters of surrounding rock based on monitoring data. 3) Forecast the surrounding rock deform in future based on history observing data. 4) Set the warning value which used to predict the unstability of surrounding rock. 5) Make the data and analyzed results visualized, which is based on VTK.
Data Base, Model Base and Visualization.

Of course, the quality of the analysis data depends on these parameters [1].
For profile fit function, the data from each x-ray peak are empirically fit with the equation.
To get a good profile fit of an x-ray peak, the number of data points above the FWHM should be at least 5 to 7 points [7-9].
For an x-ray peak, the number of data points above FWHM is (5) From Table 4, only 0.03o step size has the number of data points that begins to develop good models.

NaCl (0–15 g L–1) in growth media had no effect on measured ORP (data not shown).
Comparison of the abiotic data with the biooxidation data (any concentration) indicated that Fe(II) oxidation by S. metallicus started after a short lag time but that the rates of oxidation declined with increased NaCl concentration.
Data from the electrochemical monitoring of Fe(II) oxidation by S. metallicus in media with 0–6 g L–1 NaCl.
The data were consistent with those for cell growth (Fig 2) and Fe(II) oxidation.
Final Ni concentrations in leachate (up to 0.5 g L–1) were much lower than reported data for nickel concentrate leaching (up to 23 g L–1 Ni) [7].
