We find that the electrolyte cation (K+ ) undergoes
sorption and desorption during the system's reduction and oxidation, respectively.
During reduction anion is expelled from the film.
While uptake of cations occurs during reduction, transference of anions/solvent molecules takes place during oxidation of the film.
All data were collected using an EG&G PAR 273 potentiostat connected to a personal computer.
These forms may explain the double oxidation and double reduction apparent from figure 1.

After 45 minutes, there is a slight reduction in the amount of NaClO3 adsorbed.
At the end of the experiment, there was a reduction in chlorate adsorbed of less than 5%.
In research done by Thirumal and Kaliappan [4], close examination of the data in their graphs, show peaks around 45 minutes after which small reductions are shown in adsorption.
To obtain greater reduction in chlorate, the brine was then sent through 3 columns in series.

This reaction is called the conversion reaction that involves the reduction and oxidation of metal nanoparticles, accompanying the formation and decomposition of an amorphous Li2O [1].
X-ray diffraction (XRD) data of the powder specimens were collected on a powder diffractometer with Cu Kα radiation.
The reduction of Fe3+ to Fe0 would be occurred around 0.85 V, and then the reduction of Ga3+ to Ga0 and alloying reaction of Ga0 to LixGa would undergo at lower voltage region.
The both reductions of Fe3+ to Fe0 and Ga3+ to Ga0 might be occurred at the same time during the initial Li insertion.

Energy saving and emission reduction, reduce pollution, and pay attention to the environment construction is the trend of the future.
The data statistics shows that building energy consumption is accounts for 40% about of total world energy consumption.
Around the spirit of Copenhagen Conference, energy conservation and emission reduction, establish the spirit of green architecture, improve protection awareness of environmental and resources, to make the best use of utility and coordinated development of nature, society and economy[3].
First of all, beginning from people's awareness, the architects should have the concepts of energy saving and emission reduction, green, ecology and so on, try our best to protect the environment.
Finally, the users of buildings should also have the concept of energy saving and emission reduction, deal with harmonious coexistence relationship between the green building and environment, make the green building protect the natural environment while provide people with comfortable and healthy activities space.

According to the design parameters and the data of the blade the manufacturing industry provided, a numerical investigation on the flow has been carried on in the last three stages of a wet steam turbine.
This process not only causes the reduction of the working medium, but also affects the mainstream and influent the flow at the next stage.
The liquid mass fraction is relatively lower at the final rotor trailing edge, mainly due to the oblique shock wave, which causes the reduction of airflow velocity, the rise of pressure and temperature.
There are two low pressure locations, the pressure reduction near the blade is due to the leakage vortex, in the meantime, the pressure reduction away from the blade is due to the passage vortex.

This simulation, unlike other simulation techniques, can
provide new data and insights on nanometric machining; which cannot be obtained readily in any
other theory or experiment.
The α- to-β transformation results in a significant reduction of the atomic volume from 18.38o,A3 to 14.19o,A3 per atom or a densification reduction of about 22.8%.
Because β-silicon phase only existed under the high pressure and wasn't stable during the whole cutting process, these data couldn't explain absolutely the change of volume.
So, it needs to testify with more theory and experimental data.

The attenuation
or deterioration of signals, arises from physical phenomena in transmission lines, limits
achievable data rates and transmission distance.
In such severe environments, sophisticated pulse-shaping techniques such as equalization, preemphasis, need to be employed to increase the data rates [1].
The input data is XOR'ed with a pulse-width modulated clock in order to provide timedomain pre-emphasized data.

It was pointed out that the new evaluation criteria would contribute to energy saving and consumption reduction of power enterprises.
The data of calorific value difference show in the fig. 2.
We consider that the current standard for calorific value difference between coal as received and coal as fired is too loose to make positive impact on energy-saving and emission-reduction of power plants.

High-resolution satellite remote sensing image are mostly used for accurate updating of GIS data.
As the primary GIS data, urban roads on the image show the rich geometric features and radiation characteristics, that edge detection and grouping becoming an important way to solve the road extraction.
Due to high spatial resolution (1 to 4 m), fast orbit repeatability, rich multi-spectrum information and stable, affordable acquisition cost, remote sensed images have been taken as the main data source for road extraction.
However, in high-resolution images, roads may be hidden or not visible, and their surrounding environments are very complex [5], especially in urban areas, where objects like zebra crossings, vehicles, trees, building and shadows cause noises and reduction of contrast between roads and background.
Then line support regions are detected from grouped pixels and it makes a great reduction of the interference coming from background.

After running a cycle, select the corresponding output files to collect vehicular and pedestrian delays data, queue length data, travelling time data, which belong to the data collection point sets in the simulation system [2].
These detailed data are shown in Table 3.
And the queue length data are shown in Table 4.
After running a cycle, the outputted data contained: travel time data, queue length data, vehicular delay data, vehicular stop delay and number of stops data.
Arranging the queue length data of the three situations, we drew a comparison chart like Fig.5.
These detailed data are shown in Table 3.
