Based on the systematic analysis of the data of 46 coalbed gas samples, this paper discusses the coal metamorphism’s influence on coaled N2 concentration in Mining Area .
In the system and finishing 46 drill coal-bed gas sample data, the author analyzed the Mining area coal seam gas content of N2 changes and causes, discusses the coal metamorphic processes of N2 and CH4 yield relationship.
Fig.1 Ratios of N2/CH4 in the 2nd Coalbed along with Coal Metamorphic Degree in Mining Area In coking coal stage（Romax=1.2-1.7%）, thermal ammonification generated N2 gradually increased, CH4 generates a relative reduction in the volume, the increase of N2/CH4.
In coking coal stage, heat ammonification generated N2 gradually increased, CH4 generates a relative reduction in the volume, the increase of N2/CH4.
In the lean coal stage, heat generated by the NH3 ammonification portion in the form of NH4+ in ammonium illite is generated, resulting in production of N2 relative reduction, reduction of N2/CH4.

It is beneficial to making considerable reduction of development cycle and cost.

The laboratory tri-axial compression results of marble was analyzed, and the calibration of the micro-properties of BMP (Bonded particle model ) in PFC2D with the test data was carried out successfully.
The reduction in strength is governed by such factors as joint geometry configuration, and intact rock properties and discontinuities properties[1].
These test clearly indicated that a reduction in rock mass strength and modulus occurs with increasing size within a certain range.
The width, length, angle and properties of pre-existing fissure influence cracking propagation mode and finally determine the strength reduction from intact rock.
We introduce the laboratory tri-axial compression result of marble, the calibrated the micro-properties of BMP with the test data, the numerical simulated experiment of tri-axial compression well match the test data.

This consisted on calculating the thermal data with a fine mesh (lower CPU time cost) while the mechanical data was calculated with a bigger element mesh (bigger CPU time cost).
This implied a reduction of 1/3 in CPU time for the rotary extrusion model.
This roller achieved an accurate final geometry and an increased material flow of 10mm was obtained as shown in the data annexed to Fig. 7.
A reduction of 1/3 in the CPU time was achieved.
The requirements for a rotary extrusion machine will be obtained thanks to the data acquired from the simulation work and the experimental tests.

The experimental data were obtained by computer data collecting system.
It can be found from the curve that the electric resistance of Ga36.5Sb63.5 melts generally decreases with temperature reduction.
During the reduction of temperature starting from 860℃, the electric resistance is reduced with temperature reduction.
However, when the temperature falls to 735℃, the electric resistance comes to rise with the reduction of temperature, and reaches the maximum by the temperature nearing 723℃.
Afterwards, the electric resistance starts to decrease again with the reduction of temperature.

In this research, nanoscale iron particles were synthesized by reduction of Fe2SO4 7 H2O by NaBH4 at low temperature to avoid oxidation during the process.
Nanoscale zero- valent iron particles can be prepared in aqueous solution via reduction of ferric iron (Fe(III)) or ferrous iron (II) with sodium borohydride [4,5].
Results and Discussion In this study, zero-valent iron nanoparticles (6 – 40 nm) have been synthesised by the method of Fe2SO4 reduction using NaBH4 as a reducing agent at low temperature.
Surface area of zero valent iron nanoparticles was analyzed by data isotherm adsorption BET (Brunner Emmet Teller) using Nova instrument based on absorption of adsorbent on N2 gas.
Conclusion Zero-valent iron nanoparticles (6-40 nm) was synthesized by FeSO4.7H2O reduction using NaBH4 as a reducing agent at low temperature and high mixing speed (650 rpm).

More recently larger blades have been used, where main advantages include an increase in wind capture efficiency, a reduction in the installation and reduction in maintenance costs per MW.
The initial measurement data shows all motion relative to the camera system, where a coordinate system transformation is applied to set the global coordinate system relative to the turbine.
Fig. 14: Tower versus blade deflection during an emergency stop Fig. 15: Vector plots that can be animated during review of captured data show 3D resultant displacements for three similar points on each blade.

VFSMOD model have been tested with field data from Iowa regions [2], Canada [3], Midwest of USA [4], and Germany [5].
The applicability and performance ability of this coupling model would be tested based on plot experiment data from 2009 to 2012 year, and experimental method and results consult literature [8, 9].
As shown in Fig.1, sediments simulated values were less than measured values in addition to the individual data by VFSMOD.
Results and Analysis Using coupling model, the reduction rate of sediments concentration had been computed under different widths and slopes of VFS, as shown in table 1.
When the widths of grassed filter strips exceed 10 m, there were not obvious changes for concentration reduction rates, and this is in line with the experiment conclusions.

In this part, a sequence of continuous binary signal is converted into N low-speed parallel data streams firstly, and then these data streams are mapped to the preset 16QAM modulation.
After insert pilot sequence, data was transmit to Inverse Fast Fourier Transform module(IFFT) and that sub-carrier modulated data is completed, To reduce ISI, cyclic prefix need sign in each OFDM symbol.
At that part, the original binary data will be obtained by the opposite processing.
We can see that using wrong pilots cannot get original data.
Pilots generated by chaotic sequence at the receiving end can correctly restore the original data after the reduction, and its error rate is controlled in an acceptable range, for error pilot reduces the data’s BER is higher, almost can not get the raw data.So the pilot mapping by using chaotic sequence generated has high confidentiality, while simultaneously restoring the error rate is low.

The flow coefficient that changed according to time was calculated, and the flow-coefficient data from the injector-needle movement were secured.
Study Method The internal structure of the Urea-SCR injector and the design data for the hydraulic circuit were secured, and the Urea-SCR injector that was actually used was reverse-engineered to conduct the study.
It is expected that this result will be the cause of the reduction of the effective-flow area.
An unsteady analysis by time was conducted, and the discharge coefficient of the changing injector was used to obtain the discharge-coefficient data using the motion of the injector needle.
