Recrystallized grains were identified automatically from the EBSD data by a program developed for this purpose, the DRG program [10].
The same data are plotted in the form of -ln(1-VV) against annealing time on a log-log scale in Fig. 1b.
The data do not follow the simple JMAK relationship VV=1-exp(-ktn) any longer.
A similar result has been observed for copper rolled to 92% reduction previously [11].

Dissimilatory sulfate reduction is a process by which the reduction of sulfate to hydrogen sulfide using an organic electron donor (e.g. glycerol) or hydrogen is coupled to energy conservation and microbial growth [2].
The line shown is the best fit based on polynomial analysis of the data.
Fig. 3 shows data from the biosulfidogenic reactor operated under three different conditions: (i) 5 mM glycerol + 0.01% yeast extract, (ii) algal concentrate #1 and (iii) algal concentrate #2.
The change does, however, help explain the low CuS production with algal biomass as this organism is not known to reduce sulfate to hydrogen sulfide (unpublished data).

Surface texturing is a widely accepted approach for friction reduction in mechanical components.
Introduction Surface texturing as a means for friction reduction in mechanical components through local cavitation is a widely accepted approach [1].
With the optimized process, the ordered microstructures with a feature size down to 5mm and smooth etched surface in large-scale are obtained and the preliminary friction drag reduction effect of the textured surface is assessed.
Based on the data mentioned above, the friction reduction effect of surface texturing was discussed.
Therefore, as a preliminary test of the friction reduction effect of patterned surface textured by the through-mask EMM, the contact angle on smooth and textured surface was measured.

Moreover, the reduction annealing could affect the appearance or diminishing WFM.
The 2D Fourier difference map of the neutron diffraction data at lattice plane [0 0 0.49c] are shown in Fig. 2.
It is found that the neutron scattering density between the observed and the calculated data at around the Cu-site increases (~4.65%) through the annealing process.
Normally, the aim of the reduction annealing process is to create oxygen vacancy in the sample.

First, five controlling factors of load were defined, which were single reduction amount (δ), reduction rate (ν), thickness of top die (ω), rotary angle (θ) and rotary way (γ) respectively, and their influence degree on load was studied later.
An appropriate material model was built to simulate, which was based on the flow stress-strain data of SA508 Class 3 steel in different temperatures and strain rates.
Before the next reduction top die should rotate an angle of 90°-θ at an anticlockwise direction.
As to this heavy and thick-walled container head, the overall forging process could be divided into three coherent stages considering the former investigation data, and the best combination mode of the values of five controlling factors was found by simulation experiments.
However, stepwise rotary way was used to raise production efficiency in stage 2 and stage 3, and smaller single reduction amount and reduction rate was accepted to reduce load.

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.

The crack affects the integral dynamic properties leading to the reduction of the natural frequencies [5].
Export analysis file, modify the damage position and depth, after many times operation, export 28 groups of data and obtain five natural frequencies database corresponding to different positions and depths crack.
Twenty groups of data are training samples, and another eight groups are testing samples to verify the network diagnosis ability.

The state council about speeding up the development of tourism opinion clearly put to greatly promote the tourism industry of energy saving and emission reduction, five years to star hotel, A level scenic area water electricity consumption by 20%.
China statistical yearbook data showed that in 90, for the national tourism since about 1/6 of the energy consumption per unit of GDP and unit value added of industry 1/11 of the energy consumption, and low consumption of industry.
Establish energy conservation and emission reduction in public technology service system and to enterprise as the main body, the combination of production for energy conservation and emission reduction technology service and the achievements transformation system.
Not only through the tourism will help others, also played the indirect effect reduction. (15) tourists to change "QiongGuFuLu" consumption habits of consumer behavior.

It may not only bring reductions in CO2 emission, but also may lead to savings in expenditure on energy.
The reduction of costs via energy saving could be the first purpose instead.
These data can teach all those involved how much energy is consumed uselessly and how they can reduce it.
Among the group members, from data analysis, essential problems for reducing energy consumption will be discussed, and their countermeasures are to be proposed and implemented selectively.
In this case power reduction rate was 30 percent and return on investment (ROI) was 2.7 years[6].
