Oxide impurity inhibited the reduction kinetics of the ilmenite, yielding a lower reduction extent[1].Suresh’s study showed that reduction rate decreased with increasing weathering degree of ilmenite[2].
Temperature had great influence on the reduction rate.
Fig. 3 Effect of temperature on the solid state reduction degree of ilmenite To determine the solid reduction mechanism of ilmenite, shrinking unreacted core model was used to analyze the isothermal reduction results.
Experimental data at the interface was used as follow: where x is fractional reduction, t is time and k is rate constant; The plot of curve-fitting was shown in Fig.4.
Temperature had great influence on the reduction rate.

On the above basis, an attribute reduction algorithm is presented.
This kind of decision table with definite form has been widely used in data mining, machinery learning, decision analysis, process control, data analysis, artificial intelligence, and so on[6-12].

To correct the reduction modes, it is necessary to have experimental data on the geometry and wall thickness deviation ends of the roughing tubes after the continuous mill.
Some data in relation to TPA-80, having in its composition 8-stand continuous and 24-stand reduction mills, published earlier [5,6,7].
Processing of Initial Data For improving the technological modes of rolling in order to reduce the length of the thickened ends, at the first stage, the analysis and processing of actual data on the end wall thickness deviation were carried out.
However, an analysis of the actual data showed that Eq.1 gives understated values of thickening due to the fact that it was obtained for reduction in one stand and does not take into account the features of the TPA-80 multistand reduction mill.
A distinctive feature of the technique is the calculation based on actual data on the volume of the end thickening, which must be reduced by a specified value when rolling the end areas of pipes in the head stands of the reduction mill.

Energy saving and emission reduction are becoming strategic issues in China.
Current Research about Energy Saving and Emission Reduction Performance Evaluation Foreign scholars study energy saving and emission reduction early.

Then, based on the involute theorem, the gear data of helical spur gear pairs we obtained.
Finally, according to the gear data, its corresponding engineering drawings were accomplished and its corresponding prototype was manufactured.
Tables 3 and 4 showed some important gear data of this two gear reducers.
According to the gear data, the corresponding engineering drawings were accomplished and their corresponding prototypes were manufactured.

At that time, the COD reduction rate(full aperture) will be 11.2%, the Sulfur dioxide emission reduction rate will be 6.5%, the Ammonia emission rate (full aperture) will be 13%, the Nitrogen oxide emission reduction rate will be 9.5%.
Then from the 35 industrial categories, select the pillar industries in Dalian City, which are also the 7 large industries of energy consumption, and then collect the specific industry evaluation index data of Dalian city in 2011( see Table 1).

Introduction Slurry pipeline transportation has greatly advantages such as less investment, construction period shortly, less environmental pollution and ease of management,causing various aspects of attention.It has been used widely in many fields.With increasing depletion of energy and intensification environmental pollution,energy-saving and emission reduction have to be solved.Thus the research of drag reduction technology plays an increasingly important role.There appears a variety of drag reduction methods.For instance,soluble high molecular weight polymer,fiber material, spiral flow, changing pipe geometry,heating drag reduction and adjusting the size of particles etc.With the analysis of the theoretical knowledge and experimental data to be established,the above drag reduction technologies had been made great progress, but there are some disadvantages and some of the drag reduction technology apply in reality still for a long time.This article will discuss micro-bubble drag reduction

This article conducted an empirical study with China’s provincial data in an attempt to test that whether China’s industrial restructuring may have an effect on emission reduction.
We would need more micro data for that purpose.
This article would use this database and collect provincial data from four-digit businesses.
This article has processed the data as follows: (1) deleted the data from mining industry, power industry, gas industry and water industry, only reserve the data from manufacturing industry; (2) rearranged the data before 2003 according to national economy industry classification(GB/T 4754-002); (3) filled up the missing data (such as added value, sales volume, gross output, output of new products, export value and other variables) in 2004 with the average value of the data from the year 2003 and 2004; (4) only reserved four-digit businesses that had complete data during 1998 to 2007.This article drew from the constructing method of indexes measuring the changes in government spending put forward by Brender & Drazen (2009), and constructed the following indexes to measure the extent of industrial restructuring: This construction is similar to that of Liu Kai’s (2007), and is called Michaeli index
All the other data of emissions come from the journal China Environment Yearbook.
