Ultrafine-grained Cu–Al alloy samples are processed by means of rolling at ambient temperature and rolling reduction exceeds 90%.
The total thickness reduction for these samples was above 95% after multiple rolling passes with a thickness reduction of 40 μm imposed in each separate pass.
Obtain the experimental data by using the software provided by Shimadzu Corporation, and then analyze of the data.

This paper chooses Shanghai Hangzhou Bay north shore as the study area, to analyze the change of landscape pattern from 1994 to 2007, the data adopts 1994 aerial image and remote sensing image with 5m resolution of 2003 and 2007, land is divided into 11 types: urban land, rural land, factory, farm land, undeveloped land, beach, forest, water, fish ponds, road and railway.
Data resources The data of this paper are aerial images and remote sensing images, the images select 3 different periods which are 1994, 2003 and 2007, the image in 1994 is aerial image (1 meter resolution) and the other two are remote sensing images which are SPOT5 images with 5 meters resolution.
Using RS images as the basic information source, with 1:100000 map, other related maps, Shanghai statistical yearbook and other document data, using graphic splicing and geometric correction, gets 3 RS images of Shanghai Hangzhou Bay in 1994, 2003 and 2007 as shown in Fig.1.
Conclusion (1) The dominant landscape type in study area is farmland which CA is in the most significantwith most prominent change CA from 44.88% to 34.61%, an reduction of 10.27.
Area reduction of beach land was because that speed of artificial land reclamation was faster than that of natural formation of beach.

The main task of the sensor node software include the system power-on self test, data acquisition, data receiving and sending, and power management, etc.
A variety of air quality sensors are placed at each node, though the comparison the data collected by five sensor nodes to verify the data transfer accuracy and sensitivity of wireless node.
After 4:00 p.m, with the crowds’ reduction and pollution reduction of gas emissions, the concentrations of harmful gases show a downward trend.
Monitoring center can display real-time data of the monitoring points,the data can be refreshed from time to time and the historical data can be displayed in tabular form.
The frequency of data collection was increased using software method, which extends the data-transfer cycles and reduces the loss rate of data packet.

Results obtained from the kinetics data were analyzed using the STATISTICA 6.0 software (StatSoft Inc., USA)
Experimental data were correlated with the Eq. (1) and considering the equilibrium values given by Eq. (2).
The average percentage mean relative deviation among experimental and correlated data was 7.5 %.
The average percentage mean relative deviation among experimental and correlated data was 6.4 %.
The average percentage mean relative deviation among experimental and correlated data was 5.8 %.

Data Source Data were collected, in part, through interviews and site visits at local enterprises recommended by the china building materials academy.
The data of production was obtained from empirical data.
Most of the transport distance data were obtained from the survey.
Therefore, systematic, quantitative evaluation of the quality of the data may help researchers to choose the more reliable data source .On the other hand, it can provide a better understanding of the reliability of the data and the results.
The data were obtained from a typical enterprise.

The testing rig is fully computer controlled and all parameters are stored during a test by the data acquisition system.
The partial conclusion can be drawn from these data that the elongation at break is inversely proportional with the UV exposure time, i.e. the material loses its elasticity the longer it is exposed to UV radiation.
After a 120h exposure time, the reduction in maximum force was only 2.8% for the HA weld, while it maintained the same value in case of the HF weld.
This tendency is shown in Fig. 8, compared to the relative reduction of the specimen’s cross-section.
All the trendlines show good correlation with the experimental data (R2 > 0.9 in all cases).

A microcontroller unit (MCU) is used to replace the common DAQ card for cost reduction.
A complete testing data can be provided by the LabVIEW at the end of the testing cycle.
The measured data were used to analyze the status of the batteries.
Based on the measured data, LabVIEW can judge battery charging and discharging.

And in recent years, along with the trends of a global energy saving and carbon reduction, the concept of producing green products with low-carbon, water saving, energy abating, pollution decreasing attributes has arisen.
The printing process is the textile printing via digital data processing through the scanners and digital imaging machines etc to input devices.
The samples adopt the color blocks drawn by the three primary colors and match with four different inks to print respectively on the fabrics in cotton, silk and polyester fiber, and then analyze data after being measured by spectrophotometer. 4.1 Comparison between nano ink and reactive ink digital printing applied to cotton fabrics Apply nano ink and reactive ink digital printing to cotton fabrics.
Collect pictures of theme image and transform them into design sketches, fabrics, data search, analysis, and then confirm the design.
Therefore, this study, primarily through the Nanotechnology with green environmental protection and reduction of carbon from Mimaki Engineering Co.

Fig.3 Variation of current with time during electrolysis Electrical conductivity of metal is well, reduction reaction began from the sample surface to form a metal-sulfide-molten salt phase interface.
This is because that the electrolytic reduction rate was accelerated obviously by the rising of voltage, while it was greater controlled by the diffusion velocity of variety of ions and medium.
Sulfur has been divided into two main groups, sulfide form of FeS and dissolved sulfur which is in the steel surface, there are 2 reduction peaks and 1 oxidation peak, electrode reaction is mainly electron transfer process, It’s inferred that FeS occurred the reduction reaction at 850 as the following shows:

, Typically, Co/SiO2 catalysts were prepared by impregnation of SiO2 with nitrate solution, followed by calcination and reduction, which formed larger cobalt particles.
The mean Co3O4 crystallite sizes were estimated from the XRD data using the Scherrer equation.
The H2 consumption was monitored with TCD using the reduction of CuO as the standard. 2.3 Catalytic experiments Catalysts were evaluated in a pressured fixed-bed reactor at 2 M Pa, 1200 h-1 with the H2/CO ratio of 2 after reduction at 673 K for 10 h.
As the catalysts were modified with ethylenediamine, a third peak appearing at around 600-800 oC originated from the reduction of cobalt-silica interaction species[7].
The reduction degrees of catalysts were calculated.
