Single industrial structure with high energy dependence Due to the influence of market demands, industrial structure based on high energy-consuming industries has become the main character of mature resource-dependent cities in Shanxi.
Thus, the industrial structure of these cities is at a low degree.
In addition, the internal structure of the secondary industry also lacks coordination between light and heavy industries.
Single industry structure causes labors gathered in single production sector, and the overall quality of the labor is low.
We should vigorously develop the recycling economy and achieve value-added processing from all parts, such as coal-based mature resource-dependent cities, they should integrate "coal-electricity -aluminum,""coal-coke-chemistry" and "coal-iron-steel" three complete industrial chains to build the industrial chain network.

All the obtained reflection planes satisfy the reflection condition of h+k+l=2n with non-zero structure factor.
This indicates that there are no systematic absences in the structure refinement.
This then determines the scattering behavior of the detected radiation from the crystal structure.
These results provide a detailed understanding of the defect structure at the targeted sites.

As the final product we obtain a ceramic material with a structure which is a precise copy of the adopted reference structure.
After processing, the ceramic material obtained replicates the structure of the substrate.
In effect, we obtained a ceramic material with a structure that was an ideal copy of the structure of the polymeric substrate.

The crystalline structure of the carrier and composite could be confirmed by XRD.
Keggin structure displays characteristic IR fingerprints in the range of 1100~500 cm-1 [14].
The spectra indicate the prepared composites have reserved main Keggin structure of H3PW12O40.
The composites had typical anatase crystal structure and also maintained Keggin structure of H3PW12O40 according to the characterization study.

Based on GC-MS data, it can be deduced that Ca(OH)2 has different catalytic activity on the steam reforming of tar with different molecular structures.
Lots of studies observed that CaO was an effective catalyst for decreasing the tar yield [10-12], but only limited researches studied the effect of CaO on tar compounds with different molecular structures [13-14].

The structure of the synthesized HA modified SA have been studied using Fourier transform infrared (FTIR) spectroscopy.
However, studies show that silicate ions are not easily positioned into the HA structure and they are displaced out from the apatite structure in the presence of CO32- in the medium [4,12].
In this way, the structure of HAESA does not collapse and the HA retains its original structure.
It was observed that varying synthesis conditions affect the structure of HA modified SA.
