Strain Based Evaluation of the Experimental Data.
Based on the Coffin-Manson model, the material parameters are shown in Table 4, which were obtained by fitting to the experimental data.
The calculation were carried out by the numerical integration of the strain-stress data (hysteresis curves) shown in Fig. 4.
The results were evaluated based on Coffin-Manson model and derived the parameters for both material, by curve fitting to the experimental data. 3.

Introduction
A ecumenic image is comprised by substantive data and they have high correlation in these images.
In addition to generic image data also have other redundancy message, for example information entropy redundancy, structural redundancy, knowledge redundancy and visual redundancy.
Diversified method of image condensation Data compression is divided into reversible compression and irreversible compression. reversible compression is redundancy reduction, irreversible compression is entropy squeezing.
Data is regarded the combine of message and redundancy.
The loss compression methods of current medical image data contain adaptive predictive coding scheme, discrete cosine transform (DCT), sub-band coding and vector quantization (VQ).

Data were used to identify the development of damage, VP and VE in the 90-layer.
The damage effect is much smaller than the experimentally observed curvature reduction.
Irreversible VP shear strains are known to develop in composites [2] but there is not much data for transverse loading.
The data and the best fit with parameters B=0.018 and β=1.5 are shown in Fig. 3a.

Graphene can be formed by the reduction of graphene oxide (GO), resulting in reduced graphene oxide (rGO).
The XRD data are obtained by using CuKα radiation with λ=1.5406 Å , showing the broad peak at 2θ ~24º as similar as the graphene peaks[13], thus these materials so-called as graphenic-like carbon (GC).
If we compared the interlayer distance with the thickness data that we got from the SEM cross-section, it shows that the graphene-like carbon (GC) sheets still consist of many layers.
For the detail data about the thickness in varying time deposition shown in Table 1.

In comparison to experimental data it was concluded that the effect of compressive stresses on the crack propagation rate was correlates with the size of the reversed plastic zone.
For shorter crack lengths, for example a = 14mm, there is a distinct reduction of the overload effect due to the compressive underload (Figure 1a).
There are two hypothetical cases. (3a) A local reduction of plastic wake, Figure 10c, or (3b) a reduction of the height of plastic wake over a wide range, Figure 10d.
The case of local reduction of the plastic wake needs further discussion.
The contact situation of the closed crack flanks does prevent a local reduction of plastic wake due to external compression.

In fact, for China's strict family planning policy, carbon emission reductions a lots. ③Carbon emission factors of economic development,GDP per capita is the macroeconomic indicators, which reflects the level of people's living standard, Of course, people hope it will continue to improve.
What’s more, the government should constraint carbon emission index of the enterprise over a certain scale, and real-time inspect and control the enterprise carbon emissions, as well as publish the data.
In order to energy conservation and emission reductions, Shandong province should actively take part in international carbon emission reduction activities, improve the discourse in the world carbon trading market and change the carbon emissions seller's role.
Increase investment in science and technology, and actively research and develop carbon-capture and sequestration technologies, alternative technologies, reduction technology, recycling technology, energy technology, biotechnology, new material technology, green consumer technology, ecological restoration techniques.
Japan has been focusing on developing capturing and storage technologies that aim to cut greenhouse gases, and emission reduction technology and equipment of fossil energy, formate a flue gas desulfurization environmental protection industry to a leading position internationally.

In the 2D-model the tools were built up by rigid, analytic surfaces.
Therefore the reduction of the spring back caused by laser assistance is 3.8°, but the reduction of the bending angle is only around 1.8°.
On the one hand the clear reduction of the sheet thickness is justified in the fact that the bending line is heated up only locally.
Thus the reduction of the sheet thickness concentrates not only on a very small zone, the zone is widened and thus the reduction of the sheet thickness smaller.
The reason is the reduction of the yield stress at a temperature of 800 °C.

Synthetically, short term experiment data and long term simulated results were considered to decide the optimum air injection position.
2.
In accumulated data, ambient temperature can present the temperature of the lysimeter inside.
This can also be demonstrated by comparing the TOC reduction data in the three lysimeters.
Results shows that the data of simulation meet the experiment data very well, which prove the model is qualified to predict longer period data for reviewing optimum air injection condition.
The initial conditions were given according to previous experiment sampling data.
