Formerly, the setting of the parameter of the strip in the above-mentioned five parts in the process of production in cold reduction mill of roll, we adopt the method of thinking and setting alone.
When i=0, ( is the number of transverse distribution in the coming strip ); B—the width of the strip; —the average backward pull in framework i of cold reduction mill of roll; —the average forward pull in framework i of cold reduction mill of roll.
Similarly, we can understand from the model of elastic deforming in roll-system, the number of the exit thickness distribution after framework 1-5 could indicate by Eq.2 : (2) In this formula: —the setting value of the depressing rate in framework i in cold reduction mill of roll; —the force of the bending and working roll in framework i in cold reduction mill of roll; —the distribution of the roll shape in the working and sustaining rolls in framework i in cold reduction mill of roll.
In the procedure of setting and calculation of the parameter of the strip, we adopt the data under the condition that we have the experimental findings about the camber and template of the coming strip.
The Table 1 show the setting data of the bending force of framework 1-5 after the combined setting technology of the parameter of the strip, and the setting result of the bending force in traditional way of optimization.

Import tariffs equivalents calculation based on carbon tariffs The data used for this study is based on version 8 of GTAP-E (Global Trade Analysis Project- Energy) database.
The benchmark year of the data is 2007, which covers 129 countries/regions, and 57 sectors.
We adopt Walmsley’s recursive dynamic method to update the data in base year (2007) to 2020.
The updating processes for population, labor, capital and GDP data are carried out in three phases (2007-2010, 2010-2015 and 2015-2020) to reflect the endowment and economic development [8].
Thus, the impacts of carbon tariffs on global and China’s emission reduction are very limited.

The intellectual primary equipments are configured with a lot of sensors, so they can convert signals from analog form to digital form, and transmit data to the automation operating system of the power grid with optical fiber ethernet in the substation.
The Rough Set Theory The Rough sets theory is a mathematical formalism to deal with incomplete data, uncertainty in knowledge discovery [1].
It can not only efficiently analyze and process the imprecise, inconsistent, half-baked information, but also can discover hidden knowledge and reveal the potential laws through data reasoning.
The main advantage of rough set theory in data analysis is that it does not need any preliminary or additional information about data comparing with probability analysis method in statistics.
Value Reduction of Decision Table The decision table after the attribute reduction should do the value reduction.

In order to explore methods of improving phosphorous and nitrogen removal in sludge reduction technologies, an advanced process combining sludge reduction and phosphorous and nitrogen removal was developed, for short, HA-A/A-MCO Process (Hydrolysis-Acidogenosis -Anaerobic/Anoxic-Multistep Continuous Oxic tank).
Introduction An advanced process combining excess sludge reduction and phosphorous and nitrogen removal is developed,for short, HA-A/A-MCO process (Hydrolysis-Acidification-Anaerobic/ Anoxic-Multistep Continuous Oxic tank), which is helpful for improving phosphorous and nitrogen removal in sludge reduction technologies[1-3].
HA-A/A-MCO process has better performance of simultaneous sludge reduction and phosphorous and nitrogen removal.
HA-A/A-MCO is an advanced sludge reduction process which is developed by our research group, whose flow path is shown in Fig.1. 1.

The results showed that the catalytic activity of TNCuPc/AF-MWCNTs towards oxygen reduction was a two-step, two-electron process for oxygen reduction.
CV of GC/ TNCuPc shows two reduction peak ( −0.45 and -0.74 V vs.
and (c) TNCuPc/AF-MWCNTs , the oxygen reduction peaks were at similar positions(-0.50 and -0.75V vs.
From the result, GC/TNCuPc shows a two-electron process for oxygen reduction (Fig. 8A).
However, GC/TNCuPc/AF-MWCNTs led to a two-step, two-electron process for oxygen reduction.

Synthesis of boride composite powder via fused and carbon thermal reduction Dongdong Meng1, a, Chengliang Ma1, b, Yong wei Li1, c 1Zhengzhou University, Zhengzhou, 450052, China a690895262@qq.com b13623816850@139.com c805358250@qq.com Key words: Fused method, carbon thermal reduction, high-performance boride composite powder Abstract.
To properly cope with the problems and meet the demand of high performance, applying the fused and carbon thermal reduction method as well as combining with the advantages of EAF are necessary not only to produce high performance and low cost boride compound but also to succeed in the industrial production and application for this material.
To synthesize the high-performance boride compound and confirm the best choice of boron source, carbon source and agent, adjusting the category and addition of carbon source, boron source and the agent during the synthesis process, according to the analyzed data from XRD, is essential.
The main reason accounting for this phenomenon is attributed to constant adjustment of the category and addition amount of carbon source, boron source to complement the loss of boron source as well as the agent for crystal type conversion during the synthesis process according to the analyzed data of XRD.
Conclusions 1) The fused and carbon thermal reduction method is feasible to synthesize the boride composite powder.

Results and Discussion The X-ray diffraction data of the SBN61 samples are shown in Figure 1.
The oxygen-reduction degree increases in the order of SBN61Ar, SBN61H1100, and SBN61H1250.
According to the X-ray diffraction data, the lattice parameters and the theoretical densities of the samples were calculated, as shown in Table 1.
It indicates that oxygen-reduction can increase the κl of the SBN61 ceramics.
However, when the oxygen-reduction achieves some degree, the deepening of the oxygen-reduction degree has little effects on the increase of the κl.
