According to the data on total output value and load amount of coal per day of Shanxi province,this paper uses grey correlation analysis model to calculate the correlation degree of the development of coal logistics and economic growth of Shanxi province.The results show that the development of coal logistics and economic growth of Shanxi province have a positive correlation relationship and the coal logistics industry will promote the economic development of Shanxi province.Based on the results,the paper makes three suggestions.First,government should provide some preferential policies for coal logistics industry.Second,the modern coal logistics system should be established.Third,the economic development model of Shanxi province should be upgraded.
III.Data The data used in the paper is from Shanxi Statistical Yearbook.The original data is showed in Table 1.
Table 1 The original data Year load amount of coal per day(car) total output value of Shanxi province(One hundred million yuan) 2006 97036 4752.5 2007 104609 5733.4 2008 105005 7055.8 2009 99689 7358.3 2010 108498 9200.9 2011 112864 11237.6 2012 118963 12112.81 2013 124405 12602.24 Above table shows that except 2009,the load amount of coal per day of Shanxi province is increased year by year during 2006-2013.Its annual average growth rate is 3.15%.The total output value of Shanxi province is also increased year by year during 2006-2013.Its annual average growth rate is 12.96%.There are two reasons to explain the development of coal logistics of Shanxi province.Firstly,pulled by the real estate industry,the national economy is growing rapidly.Secondly,Due to the free policy environment and the logistics infrastructure construction,the coal logistics is growing.Fig.1 shows the growth tendency of total output value and load amount of coal per day of Shanxi province.
IV.Correlation degree calculation Grey correlation analysis is the main part of grey system theory and used to analyze the relationship degree of tow variables[3].Its advantage is that less samples are needed.The data used in accordance with the demand of grey correlation analysis.
VI.Suggestion The added value of coal industry is accounting for 54.9% of the industrial added value in Shanxi province in 2013.But coal resources is non-renewable resources and the coal industry is one of the nine main industries which are responsible for energy conservation and emissions reduction.So Shanxi province should develop modern coal logistics to change the economic development model and promote the quality of economic growth.

The apparent creep activation energies Qc in the temperature range 398-473 K obtained for nanostructured nickel (115±15 kJ/mol) correlated with the available data on the activation energy of the GB diffusion of coarse grained nickel (Qb=115 kJ/mol [7]).
It is assumed that the observed reduction in the apparent creep activation energy of nanostructured nickel in comparison to the coarse grained nickel is due to an increased contribution of the grain boundary sliding into overall deformation.
The reduction of creep resistance of nanostructured Ni was found to take place in the case of diffusional contact with Cu in the temperature range of 398-448 K.
The effective coefficient of grain boundary diffusion calculated using experimental data is in a good agreement with the values for Al self- and Mg heterodiffusion along the Al grain boundaries.
Of coarse, our scatter is large, and it is large also for other data obtained in the direct diffusion investigations too.

Data was recorded at 10 points per mm using with a mean probe height of 120µm.
Thus, surface deformation and heat treatment produce a reduction in Ecorr but, significantly, a very large reduction, of ca. 0.5 V, is produced by surface deformation alone without any requirement for a subsequent heat treatment.
Hydrogen evolution was not observed at -0.8V vs SCE, implying that the change in cathodic polarization behavior arises primarily from an inhibition of cathodic O2 reduction.
The data in fig 2 has not been adjusted for surface roughness and it is possible that a change in roughness on etching might influence the calculation of true current density.
The Ecorr data in figure 5 was produced by SKP scanning over a ground surface which had been part caustic etched through a mask of teflon adhesive tape (subsequently removed).

At that, the estimate of treatment efficiency should take into account not only the fact of BP reduction, but also the effect of treatment on cerebral hemodynamics.
Statistical processing of the obtained data was carried out using software package STATISTICA.
Rodriguez et al. [13] in patients with DM, one could also observe the cerebrovascular regulation disorders, manifested by a reduction of cerebral blood flow adequate response to appropriate stimuli.
In the literature there are only few data on the effect of therapy by b-blockers on cerebral microcirculation at AH [17], and they are quite ambiguous.
Conclusion According to the data on 99mTc-HMPAO brain SPECT, it has been shown that in patients with AH in combination with type 2 DM the signs of brain hypoperfusion and reduced cerebrovascular reserve are identified even in the absence of focal neurological symptoms.

To analyse qualitatively, the data were grouped into categories: 10%≥S>20%; 20%≥SI>30%; 30%≥SI>40% and 40%≥SI>50%.
This analysis becomes more evident when the data are represented by concrete type (Figure 3a) and it is verified that the correlations of LTWAC1 and LTWAC2, which has presented SI lower than 30%, are not good: 0,0742 and 0,0392, respectively.
In the same way, this analysis becomes more evident when the data are represented by concrete type (Figure 3b) and it is verified that the correlations of LTWAC1 and LTWAC2, which has presented SIs lower than 25%, are very poor: 0,0003 and 0,0167, respectively.
The volumetric fraction of aggregates – related to the theoretical densities in this paper - also affected the reduction of compressive strength due segregation.
Concretes manufactured in one layer, and with density of 1700 kg/m3 presented higher reductions of compressive strength due segregation than concretes with theoretical densities of 1900 kg/m3 (one layer).

Experimental results of two sizes if filler shown that fine filler mold compound exhibited in reduction of gate chip off formation, compared to normal filler mold compound.
The demand for microelectronics package has increased tremendously in recent years because of the reduction in size of electrical components.
DOE is a technique widely used by many scientists and engineers to structure the data collection process for reducing trial and error.
DOE suggests various designs, which can reduce the number of data points to collect, while at the same time collecting sufficient data for analytical objectives [4,5].
This would lead to the reduction of possibility of gate chip off formation due higher strength of gate at fine mold compound than normal mold compund.

Though there is a lack of experimental data for high Cr steels by X-ray microtomography currently, but (b) has provided reference value for studying creep cavitation behavior in high Cr steels.
The creep data is very limited, and the extrapolation if such data using the conventional empirical methods may not be reliable.
The quantitative data also validated the description of creep damage by numerical methods.
The quantitative data provide a function of describing nucleation, growth and coalescent with creep damage exposed time in dual phase steels, but yet getting in high Cr steel.
Further work should be provided more experimental data of X-ray tomography for high Cr steels need to quantify the experimental data of X-ray tomography for high Cr steels from planning new experiments and develop new creep cavitation model that the fundamental work for the development new creep damage constitutive equations for high Cr steels under high temperature at low stress.
