For reduction 5% H2/He was used and then 25% O2/He was used for oxidation.
The data after one redox cycle was profiled in Fig. 2.
During temperature-programmed-reduction (TPR) process, the weight loss contributed to the reduction of LOS began to take place at about 700 oC.
Shown in Fig. 3 is the out situ XPS result of Ce-LOS with oxidation and reduction states.

According to the relative data and materials, the energy flowchart of Sichuan province in 2010 was drew at first, then the energy input, output, consumption, corresponding pollutants emission of Sichuan province from 2005 to 2010 were analyzed simultaneously.
How to optimize the regional energy flow and how to implement energy conservation and emission reduction has become the urgent work.
We counted the CO2 emissions in Sichuan province 2005~2010 according to equation 1 and related data.
Comprehensive evaluation of coordination degree in complex system At first, we make indicator value for standardization according to the relevant data in table 2, then take k=2, and count the coordination degree of two subsystems respectively and the synthetic coordinate degree of complex system (see Fig.2) according to the equation 2, 3 and 4.
(4) Strengthening the energy conservation and emission reduction of transportation sector and building sector.

This study analyzes the characteristics and reasons of the eco-hydrological evolution based on the 1982 and 2006 phytoplankton and zooplankton survey data[8,9].
Water quality data is from 1998 to 2010, the rainfall data is from 1956 to 2010, and the measured runoff data of Bengbu Gate is from 1956 to 2000.
The reduction of dry season runoff and flood runoff in Bengbu Segment is one of the reasons for the reduction of organisms.
But the mechanism is not clear due to the lack of data in survey data of aquatic organisms.
Due to lack of monitoring data of the Huaihe River aquatic organisms, the article only analyzes the eco-hydrological evolution of Bengbu Segment resulting in some limitations, which needs increasing monitoring points and frequency to strengthen the monitoring efforts of aquatic organisms in the Huaihe River.

The chip reduction coefficient was calculated using reciprocal of cutting ratio mentioned in equation 1.
The marginal effect of feed rate on shear angle and chip reduction coefficient was observed.
These finding has been mapped with literature data [13].
The observations are also scattered above and below the centre line confirm the data suitability for the obtained results.

To examine the impact of different input data assumptions on the results of energy certificates, sensitivity analysis was performed.
Specifically, the project had the following objectives: (i) Identifying sources of uncertainty in the calculation and issuing process of energy certificates; (ii) Analyzing the impact of different input data uncertainties onto Key Performance Indicators (KPIs); (iii) Derivation of comprehensive input data documentation to mitigate the impact of non-well documented input data for energy certificates.
Table 1: Categorization of uncertainties of input data for building energy certificates (first published in [1]).
Both groups got the same input data documentation of 16 buildings and were asked to issue energy certificates.
To furtherly be able to clearly understand the relation between input data uncertainties and impact on the corresponding output data, different alternative approaches seem promising.

According to the production data of a rolling H-beam factory, the FE model of hot continuous rolling process of H-beam is built.
In which ——Datum deformation resistance, that is resistance in condition of =1000℃, and s-1 ——the degree of deformation (logarithmic strain); ——the deformation speed; , ——the regression coefficient, whose value depends on the steel grade For the 25 steel, =150.6MPa,,,,,,。
Because of different reduction of each pass, metal flow hassubtle changes, but the trend is similar.
In this paper, It mainly analysed that the reduction of web is not varied at 21.36%, when the metal flow of web changes , the metal flow will change.When the web reduction is 21.25%, the X, Y, Z direction node displacement contours are respectively shown in Fig.4 (a), 4 (b), 4 (c).
That is, the web reduction increases and the the free extension of flange increases.

For the obtained data, the ODF was calculated using the ODF analysis program (Standard ODF 3.4.1) [11] by the iterative series expansion method. 3 Results and Discussion Fig. 1 Optical microstructures of laminates.
The average, maximum and minimum peel strengths of the laminate with a rolling reduction of 40% was higher than those of a rolling reduction of 50%.
The PE layer of the laminate with a rolling reduction of 40% about 1.6 times is thicker than that of the PE layer of the laminate with a rolling reduction of 50%.
Fig. 5 shows ODF of PE layer in the laminate with a rolling reduction of 40% and 50%.
It is found that PE layer in the laminate with a reduction of 50% is higher in (001) [100] orientation than PE layer in the laminate with a rolling reduction of 40%.

Strength Reduction Method and Poisson Ratio In 1975, Zienkiewicz proposed the concept of shear strength reduction factor to indicate the ratio of the maximum internal shear strength of the slope soil to the practical shear strength exerted by the external load in the condition that the external load remains constant.
The specific calculation is as below: to have the material strength value divided by the reduction factor F, and then to gradually increase the value F so as to decrease the intensity up until it is instable.
Document [3] employs the Poisson ratio reduction method deduced from the experimental data, in which the calculation of the Poisson ratio is as below: vtj=vi+Fj(vt-vi) (j=1,2,…
The calculation process of FEM goes as follows: (1) Preset βj=1.0, 1.2, 1.4, 1.6; (2) Preset a strength reduction factor F1, and then calculate the reduced strengths C1 and φ1 according to equation (1)
Gravity Increase Method The calculation principle of gravity increase method is quite the reverse to that of strength reduction method.

The risk analysis is a systematic and structured data processing to identify potential hazards.
The qualification of risks consists of choice of method and determinative indicators, input data and simulation of model with drawing results.
Minor Minor reduction in technical performance or supportability.
The category of high risks includes risk of reduction of indoor air quality (draft or cold radiation) and risk of reduction of the efficiency of the ventilation system.
