Using three TM images of 1991, 2004 and one OLI image of 2014 as data sources, we extracted dynamic change information of desertification land during 23 years in Wuda district in Inner Mongolia, discussed spatio-temporal evolution processes of desertification land of this area aiming to provide decision-making references for desertification control and eco-environmental restoration and reconstruction.
Landsat 5 TM images of 1991 and 2004 as well as Landsat 8 OLI image of 2014 as data sources (http://glovis.usgs.gov) were selected depending on their acquiring time from June to October for clearly identifying vegetation, and prerequisites of total cloud less than 3% preventing more information from losses.
Results and Discussions As shown in Table 1, we can see that the area of desertified land in Wuda region experienced a remarkable reduction process (114.23 km2) from 1991 to 2014.

The reliability of the regression model was tested by the correlation established with the experimental data through the following statistical analyzes: Pareto graph and response surface.

The factorial experiments showed that the interaction of glycerol with both modified clay and cassava starch was significant for the reduction of elastic modulus.

Electron backscattering diffraction (EBSD) data showed that DRX is caused not only by diffusion but also by twinning in the alpha phase.
Introduction In the next few years, automobile emission regulations will be strengthened for the purpose of greenhouse gas reduction.
The EBSD data showed that parts of their boundaries were twins, and their GOS values were lower (black arrow).

In the EU, the latest data shows that 32.5% of plastic waste is recycled and 42.6% recovered through energy-from-waste [3].
Statistical analysis Statistical significance between the studied specimen data was tested by using Daniel’s XL Toolbox Excel software.
The data were analyzed by using the one-way ANOVA Bonferroni-Holm post hoc testing algorithm. 3.

The depth data points of the offshore terrain and verification points are measured water depth data for May 2017.
The value was based on the bottom water depth data and sediment particle size distribution.
The data is calculated and obtained with the range of 0.012-0.019.
Calculate the model at 13:00 by calculating the station's measured flow data at stations 1# and 2# and 10:00 on May 7, 2017, and at 10:00 on May 8.
The wave data of Xinhe Beach is from the Damutu Ocean Station.

High-energy x-ray diffraction experiments were performed to obtain reliable diffraction data for the liquid phase of metallic glass-forming Zr-Cu binary alloys.
The data acquisition process was repeated typically three times to confirm the stability of the intensity profile obtained.
The total structure factor, S(Q), was extracted by normalizing the corrected coherent intensity data.
The RMC method has been shown to be a useful tool to construct a three-dimensional structural model of disordered materials using mainly experimental diffraction data [17].
The data of the constituent elements near their melting point were taken from the literature for a comparison [20].

This regenerative device control system using MCU by reading the temperature controller and pressure sensor data, output analog quantity to control the frequency converters, which control blower speed to achieve the control of air flow into the burner, to achieve temperature control.
MCU by reading the temperature controller and pressure sensor data, through the analog to control the inverter, the inverter controlled the air supply of blower, in order to achieve air temperature control.
Figure 10 is test results, experimental routes and bus reciprocating times is the same with improve before, as shown in Figure 8 can be seen the regeneration time shorten to 16 minutes or so, more than 50% reduction to meet the practical requirements.

Some algorithms including the gray scale processing, median filtering, edge detection and least square fitting method of measured data were analyzed to develop image processing and tool detection software of ball-end cutter.
The later method is demanding on the measurement environment, and it can only measure the simple structure; it is difficult to measure complex shape under the conditions of the cumbersome process of reading data and the long measurement time.
Common noise filtering methods mainly include mean filtering, median filtering, gradient inverse weighted method and noise reduction method [5].

Fourier transform infrared spectroscopy(FTIR) and X-ray diffraction patterns(XRD) data suggested that the nanoparticles were composed of Ag and PPy.
Silver nitrate(AgNO3), poly(vinylpyrrolidane) (PVP), ethyl cellulose and other chemicals were of analytical grade and were used without further purification. 2.2 Synthesis of Ag/PPy nanoparticles The Ag nanoparticles were synthesized by polyol reduction using PVP as the capping agent. 10mL 0.3M AgNO3-ethylene glycol solution and 6mL 0.15M PVP-ethylene glycol solution were injected simultaneously into 10mL ethylene glycol.
However, when the content reaches certain point, the adhesive attraction between enzyme film and platinum matrix will be reduced due to the decrease of their effective contact areas, which consequently causes the response current of enzyme electrode reduces. 2 4 6 8 10 12 10 15 20 25 30 35 40 45 50 Current(uA) Content of Ag/PPy(wt%) Fig.7 Effect of the content of Ag/PPy on the response of the GOx electrode. 3.6 Response time, linear range and detection limit of GOx electrode According to the equilibrium current data in 5 mmol/L glucose 40.0±1.0 °C and pH value of 7.08, the current response of the enzyme electrode reaches 94% of its steady maximum value in 5 seconds, 97% in 12 seconds, and achieves the maximum in 16 seconds.

This is consistent with other published data.
The main stream has a high velocity due to the area reduction and friction causes re-circulation to occur in the gaps between the tubes due to low pressure in the separated wake regions.
This suggest that the prediction of separation and re-attachment angle in this study is agreed well with the published data.
