Fig.1 Flow chart of ferrite rolling test Fig.2 Temperature distribution photo at 800°C Fig.3 shows the temperature distribution data along both rolling and transverse directions of the strip.
(a) Rolling direction (RD) (b) Transverse direction (TD) Fig.3 Temperature distribution data of strip before rolling at 800°C Results and discussions Rolling Parameters.
Fig.4 shows the reduction effect on the rolling force in the ferrite temperature range.
It can be seen that reduction has an obvious effect on the rolling force.
A higher reduction always achieved higher rolling force.

WARDM Algorithm The WARDM model proposed in this paper is divided into three phases: data input stage, data mining stage and data output stage.
At the same, with the reduction of the wminsup, the advantage is more obvious.
The WARDM algorithm has good stability and is more applicable to data mining in large-scale data sets.

Data were analyzed by Kruskal-Wallis and Mann-Whitney U test at p<0.05.
Evaluation of biofilm formation was assessed through the XTT reduction assay at 492 nm [12, 14].
By using XTT reduction assay, the amount of biofilm formation are expressed as the optical density (Table 1).
But, within these AgNPs groups, the reduction was not dose dependent.
They also showed the reduction of flexural strength of PMMA with the increase of AgNPs in heat polymerized PMMA resin.

Cavity volume of ring after compression to different reductions.
All rings expands when m < 0.09 irrespective of the reduction.
The white contact area is determined by binary data analysis of the micrographs observed in a microscope in five different radial positions as shown in Fig.7.
Fig. 8a shows the change in m with increasing reduction.
The friction coefficients m are constant at a reduction less than about 20%, while m decreases at a reduction of 30%.

The most useful function of data mining technology is extracting valuable information and knowledge from irregular data.
Data mining technology [2] is a process to extract unknown before while valuable information and knowledge from those seemingly fragmented and irregular data.
As an analytical tool, Data mining technology is usually constituted by multiple steps.
By means of information management technology and database technology to achieve data integration and logistics management, thus data mining technology provides basis for intelligent logistics decision-making system.
At present, the application of genetic algorithms is a relatively mature technology of data mining techniques.

The simulated experiment shows the modeling data is fit to the field data.
And even through Gleeble press and other equipment, it is not easy to attain accurate data.
To get the resistance of deformation model using neural network technology from the field data is an attempt to solve this dilemma.
In the same time, is calculated with Eq.(9) based on the data in table 1.
A model is shown in Figure 2: Fig.2:The deformation resistance of Q235 between 1310~1360K with rolling speed 52.5m/s and reduction 35mm Compared the data in Fig.2 with available data [1], the difference is less than10 %.

Also, reduction of molybdenum trioxide by hydrogen or carbon has been reported in the literature [4, 5].
In the present study, carburization-thermal process for reduction of MoO2 is done by using carbon [4, 6].
For identification purposes of crystalline phase composition, diffraction patterns obtained were matched with standard diffraction data (JCPDS) file.
Summary The reduction process of MoO2 to metallic molybdenum can be completed by a two-stage reaction process.

The displacement has been studied for three typical kinds of aluminum reduction cells (semi-graphitic, graphitic and graphitized) after 30 days start-up.
Clearly, in our country, the 350 ~ 400KA aluminum reduction cell has gradually become the mainstream, and the cell deformation increases with the higher amperage [4].
Researching the relation between the graphitization degree of the cathode materials and the cell deformation on the basis of the thermo-electric field analysis, this paper could provide the valuable data for the cell technical improvement and the development of the new cell.
