Substituting the above control experiment data into the above formula, the value of the specific reaction rate at any temperature can be obtained.
Results and Discussion Preliminary Results After many experiments and adjustments, it was found that in the case of 200 pellets, the most consistent with the original experimental data.
The results obtained are not much different from the experimental data in the literature, which proves that this method is feasible.
The degree of reduction and the reduction time of the pellets are obtained in continuous time.

Reduction of GO by TGA.
In order to ensure the reduction of GO by TGA, hydrochloride reduction of GO was carried out to compare the quality of TGA to that of the hydrochloride reduced GO.
This is attributable to the partial reduction of GO to graphene.
These XPS data suggest that the oxygen-containing functional groups have been partially removed restoring majority of the conjugated graphene network after reduction.

The main phase of the reduction product was Fe2B, FeB and SiC.
Though the best combination has in the nine experiments, but experiment were needed to increase some data to analyzing if samples has were reacted completely.
The main phase of the reduction product was Fe2B, FeB and SiC.

Stability criterion The shear strength indexes are c and φ, Fk is the strength reduction factor.
Based on such a criterion for evaluating the instability, it is convenient to compare the calculated displacement with infield-measured data, which is helpful to monitor the development of safety of the slope and make engineering judgment based on in field measured displacement data.
At each load step, the calculated data could be output as required, such as the deformed mesh, displacement and stress of elements and nodes, stress and deformation contour map.

The texture of the secondary recrystallized sample under 97.2% cold rolling reduction rate condition consists of {110}<112> orientation, which is quite different from Goss ({110}<001>) orientation obtained under lower cold rolling reduction rate conditions.
There are some experimental data demonstrating that these grain boundaries have high energy (HE) [3].
In order to change a primary recrystallized texture, it is effective to control cold rolling reduction rate.
The orientations after secondary recrystallization were measured by the back Laue reflection method, and its ODF was calculated from the secondary recrystallized orientation data using the series expansion method.
The sample under the 92.6% cold rolling reduction rate condition has highly oriented Goss texture.

Introduction Air pollutant emission reduction effect is an important indicator for the evaluation of port enterprise, national and regional energy saving and emission reduction effectiveness.
Although Eq.1 is relatively simpler, there isstill a considerable amount of work needed not only having to investigate fuel or energy consumption of all national container port,but also to statistic and analyze the data.
Hi,j,k=l=0l(TEFi,l×Tj,k×10-4) (2) In Eq.2, Hi,j,k: same as formula-1; TEFi,l: the ithair pollutant’s emission factor per unit throughput of lthcontainer terminal handling facility(t/ TEU), estimated by fuel consumption method (Eq.1) using the actual investigation data of throughput, fuel or energy consumption in representative container terminal; Tj,k: the throughputamount of jth port’s container terminal in kth year (TEU/a).
Fig. 2 Container port throughput in 2012 and highway distributing minimum mileage Fig.3 Air pollutant emissions in 2013 from port handling and highway distributing In the calculation above mentioned, the state published data of coastal and inland river port throughput and unit energy consumption, container throughput, heavy truck and ordinary truck unit mileage energy consumption in 2013 [24], and container handling facilities energy consumption of unit throughput (coastal and inland river port in the same) estimated by this research investigation are used, respectively, into Eq.4 and Eq.5.
Evaluation of air pollutant emission reduction.According to the published data of coastal and inland river port cargo throughput and container throughput from 2001 to 2013, this research has obtained the non containerized cargo throughput of port, and the classification of statistics formula predicting throughput (Fig.5 to Fig.6(left)), in which the correlation coefficients range from 0.971 to 0.998.

Research on Evaluation of Soil Fertilities of Farmland at County Level in Nongan Based on Data Mining Li Ma, Guifen Chen, Liying Cao, Yueling Zhao Jilin Agricultural University, Changchun, Jilin, China Mary19801976@sohu.com,752922110@qq.com,24426266@qq.com,14964585@qq.com Keywords:Evaluation of Soil Fertilities of Farmland; Rough set; Decision tree; Data mining Abstract:This research used the method of rough set and decision tree in data mining, building the evaluation model of soil fertility, to evaluate NongAn of Jilin province farmland productivity.
Select HAYATA 452 final, 11 paddy, vegetable 9, located in the county's 26 towns, farmland will generate sample data underlying database.
But in soil domain knowledge, a lot of data, such as soil humus layer thickness or floating-point values, are continuous values or the form of floating point Numbers, so the data must be processed before performing discrete attribute reduction, in order to accelerate the efficiency of knowledge acquisition.
With Soil data, the condition attribute is the 24 item properties as the evaluation factors above, the decision attribute is the soil fertility level, the rough set attribute reduction process is: Obtain the nuclear of condition attributes, and use it as the initial reduction.
In this paper, decision tree method is used to construct the decision tree model, using the rough data after intensive Jane,after reduction of the soil data input the decision tree algorithm, do decision tree structure and pruning, to get fertility level of the decision tree.

In OFDM data is transmitted simultaneously through multiple frequency bands, the effects of multipath delay spread can be minimized.
OFDM has been proposed for many radio systems such as the next generation mobile communication, wireless LAN, digital audio/video broadcasting, and high-speed cellular data.
The Papr in Ofdm Systems In OFDM systems, the baseband time domain signal consisting of N subcarriers may be written as , (1) Where is the subcarrier spacing, NT denotes the useful data block period.
Partial Transmit Sequences (PTS).In the PTS approach, the input data block is partitioned into V non-overlapping subblocks, which are combined to minimize the PAPR [4].
However, for both schemes, to recover the data, the receiver must to know which vector had actually been used.
