However, test data of characteristics are based on samples of rock or soil, the size of sample is much smaller than the range of rock or soil should be considered.
The data received from samples are characteristics of the given point.
According to different auto-correlation functions, kinds of expressions of variance reduction function were researched in recent years[12].
From geological data of salt mine area, terrane of cavern, top and bottom terrane are approximately in horizontal direction.
Since lacking of test data, fluctuation range are supposed as 20, 30 and 60 meters respectively, and variation coefficient as 0.10, 0.15 and 0.20 respectively.

That can lead to the binder hardening speed reduction.
The water cement relations of a normal consistence are considered as the output data.
As a result of the experimental data processing, the equations reflecting the influence of the varied factors on the studied indicators of the low-clinked binder properties have been obtained.
The analysis of the data provided in Table 4 has shown that a certain discrepancy is observed between indicators of the LCB normal density and the values of the water-binder relation of standard solutions with normal consistence.
The obtained data have shown that applying the coal ashes as a mineral additive allows receiving the low-clinked binders on the basis of the Voskresensky Portland cement.

Data are tabulated and evaluated based on different parameters incorporated; meanwhile comparisons are made between concrete and composite footbridges.
Results and Discussion The data of displacements and accelerations were collected at several critical points.
There is a significant reduction of responses between 100mm slab and 150mm slab.
Accelerations have exactly same trend as displacement (data not shown).
Any further increase in deck thickness after 250mm doesn't show any significant reduction in responses.

In the tool manufacturing phase 3D measurement data contributes in reducing the time frame for CNC machining processes, for the try-out phase, future tool reproduction as well as for repair and maintenance.
Due to these modifications, tools geometries differ after try-out from the simulated tool shape or the CAD data model.
This results in a full-field 3D data deviation plot between measured and nominal shape, available as discrete values or color plot (Fig. 11).
The inspection results are then exported as reports or tables to data bases and can be stored and if necessary post-processed.
The measurement workflow teaching process is once done on the 3D model extracted from the CAD data set of the component (Fig. 14, right) as an off-line process.

Thus it is necessary to study the reduction of CH4 in these fields.
Thus it is necessary to study the reduction of GHGs.
Thereinto, the gas supply system includes a gas cylinder and an air compressor; the water supply or drainage system involves a vacuum, stop valves and so on; the image acquisition system is composed principally of camera device and video data acquisition card; the data acquisition system mainly consists of FCC6000 data server and BT5000 supervisory & control configuration software.

Based on above data, the average dissociation rate was calculated, and it is 2.8×10-2 m 3·h -1.

In the second part of the combustion face, reduction reactions are occurred (endothermic reaction), is called reduction zone.
, based on the obtained heat and mass balance calculations data, is carried out as to application of certain blasting interfusion types for effective underground gasification process management.
(10) where: – the average heat flow in 1 m2 of the surface rock walls channel by radiation and convection, J/m2, Sn – the surface of the coal channel, m2, τ – time for coal seam gasification to the coal channel width, s, Qi – the intensity of gasification, kg/s; Q5 – additional heat losses into the environment (unaccounted losses), made on the basis of practical data.
This greatly simplifies the data processing and allows to quickly obtain end-results with a high degree of compliance.
Definition of the Mississippian–Pennsylvanian Boundary in the Lviv–Volyn Coal Basin (Western Ukraine), Based on Palynological Data.

Results and discussion Fig. 1 XRD patterns of (a) pure aluminum hydroxide and (b) the catalyst after reduction in hydrogen atmosphere at 400 ℃ XRD patterns of pure Al(OH)3 and the catalyst after reduction in hydrogen atmosphere at 400 ℃ for 1 h are shown in Fig. 1.
Fig. 1 pattern (a) shows the XRD pattern of pure Al(OH)3 and Fig. 1 pattern (b) shows the XRD pattern of the catalyst after reduction, it can be seen that the peaks of the catalyst support changed a lot after reduction.
TEM data suggested that there were more carbon onions encapsulating metallic cores in the product synthesized using C-1.
The data indicated that when alumina was used as support to prepare catalysts by impregnation, if the content of iron was low, the catalyst containing small-sized iron nanoparticles was obtained, while if the content of iron was increased catalysts containing large-sized and agglomerated iron nanoparticles in the range 45-65 nm were obtained, revealing the weak interaction between alumina and iron nanoparticles and the correspondingly high mobility of iron nanoparticles on catalyst support.

Therefore，it is necessary to optimize the structure parameters of the cutting head, which has a important theoretical and practical significance for the reduction of the energy consumption.
Optimization Model of Cobalt Crust Cutting Head Structure Parameter On the basis of large amounts of data and test, John Halkyard and his company take the best method for crushing cobalt crusts and bedrock should be the spiral mining head, disc cutter cutting, drag cutter cutting and water jet cutting.
According to data and statistics, the most economical method to collect cobalt crust is spiral mining head, which is researched in this article.
An appropriate reduction of traction speed is helpful for the increase of the chip thickness and the reduction of energy consumption.
And this is a great help to the reduction of energy consumption and the improvement of energy efficiency.

Introduction Rough set theory is a mathematical theory of reasoning about data which can be also used to deal with vague and uncertain problems [1].
Computing core and attribute reduction are very important issues of rough set theory.
For many algorithms on attribute reduction, the core is usually calculated at first, and then heuristic knowledge is combined with core to find the reduction.
Decision table reduction based on information entropy [J].
A quick attribution reduction algorithm with complexity of max {O (|U| |C|), O (|C| 2 |U /C|} [J].

Multi-staged combustion was demonstrated as a practical NOx reduction method in the late 1970s [1].
Nitrogen element in liquid fuel is converted to nitrogen gas molecule through gasification reaction in reduction condition.
As shown in the data, the peak temperature region is situated around center of the flame, which is around 1200℃.
As shown in graph, this new type of burner has two major advantages in NOx reduction over other conventional burners.
