For modeling the structures of crystalline complexes of Al2O3, an algorithm for generating the cluster structures was developed.
Cluster Models of Al2O3 Structures.
Basal-plane projection for a model of the periodic structure of Al2O3 with the explicit secondary structure, the elements of which are the Al4O6 clusters.
Numerical simulation of Al2O3 crystalline structures allows controlling the structures on multiple length scales and creating brand new materials with an ultrafine-grained structure as well as materials with unique properties and heightened operational characteristics [11-14].

The results illustrated that IPN hydrogel with 2 phr MBA provided a greater water absorption and swelling property than IPN hydrogel with 1 phr MBA due to the interior porous structure within polymer matrix.
It might be due to the appearance of interior porous structure within IPN hydrogel as shown in Table 1 (cross section view).
Due to the interior porous structure within IPN hydrogel network, it could facilitate water diffusion and also led a higher water absorption or swelling property [7].

There is a cross-linkage between Ge and the Se chain structure, due to which the rigidity of the system increases, and hence the glass transition temperature also increases [11].
It is defined as the mean number of bonded neighbors per atom in the structure [16] m= αNGe+ βNSe+ γNSbα+β+γ where α, β, γ are at. % of Ge, Se and Sb and NGe = 4, NSe = 2, NSb = 3, respectively.
This increases the rigidity of the structure.
Conclusion The addition of Sb content shows that there is an increase in cross-linking of structure due to which average coordination number increases and hence rigidity of the system also increases.

In order to utilize cartilage and CS more extensively, more and more researches are being focused on the bioactivities of CS with different structure, its content determination and structure identification.
Interestingly, these CSs from different species have different structures and bioactivities.
In order to further illustrate the structure-effect relationship of various CSs, More and more researches have been focused on their composition and fine structure analysis.
Structure properties of CS and corresponding chondroitinase are shown in Fig.1.

There are varied of pore structure forms in the minerals, the structure of the zeolite, the diatomaceous earth, and some expansive mineral materials are three-dimensional pore structure, the structure of the smectite, vermiculite and graphite are two-dimensional pore structure, the structure of the palygorskite, the sea bubble stone and asbestos are one-dimensional pore structure.
Industrial Wastes Some of the industrial wastes have extensive pore structure, such as: lignin extracted from paper industry waste, sugar bagasse and some other waste generated.
These carbon micro crystalline and amorphous carbon are connected by a carbon oxides built into activated carbon block and space structure.
And the pore structure has a good adsorption performance.

Structure adhesive.
The performance parameters of structure adhesive are shown in table 3.
After structure adhesive solidifying, the specimens were finished.
Steel bar and structure adhesive were pulled out together.
To this failure mode the anchorage bonding force was from chemistry adsorptive attraction between structure adhesive and concrete importantly, but the friction force or mechanical bite force was weaker than above force.

Blue Luminescent Center The blue luminescent center is type I Pwo crystal, the local area structure distortion Ⅱ type Pwo structure for the results.
(I) the price of tungsten metal lead acid has two kinds of structure and aberrant, they inspire spectrum and emission spectra of significant differences.
Two kinds of structure of the tungsten salts shine characteristics coexist in the PWO crystals.
The different structure crystal and different crystal orientation, X-ray diffraction pattern and diffraction spots position is different, each diffraction spots and crystals in various faces have certain corresponding relation between the diffraction of spots symmetric relations also reflects the crystal structure of symmetry.
The blue light center Pbwo4 is white tungsten mine the structure of crystal, excellent flashing performance, the crystals in luminous center, because of crystal w-o atom in groups WO42-tetrahedron structure, the blue glow of the rules of the center for WO42-and other white tungsten mine of tungsten acid salt of similar luminescence materials.

The results showed that the corrosion area has loose structure and is covered by obvious corrosion products.
The metallographic structure of flanges on both sides is martensite and ferrite, Cr rich corrosion-resistant phase exists at the grain boundary, and the valve cover structure is tempered martensite without Cr rich phase.
It can be seen from the metallographic structure analysis that the matrix structure of the flanges on both sides of the hydraulic valve is tempered sorbite.
The valve cover structure is Tempered Martensite, and there is no Cr rich phase on the grain boundary.

Hexagonal mesoporous structures were achieved in both the F127 and the P123 templated systems.
On the contrary, both the microimages for F127-80S and P123-80S present a well ordered mesoporous structure.
From the literature, only worm-like meso-structure was achieved by Yan et al. [11] using the F127 as a template, however in our case, the F127 templated 80S samples presented fine-ordered meso-structure.
The regularity of the mesoporous structure became poorer as the SiO2 content decreased.

In addition, different forest structure and canopy characteristics led to different stand microclimate, that significant influenced soil temperature and soil water content [8].
Statistical analysis The differences of soil respiration, canopy structure parameters, soil nutrient, forest microclimate, and tree growth traits between plots was test by ANOVA.
The variance of tree canopy structure was related to tree traits (e.g. crown shape, leaf shape), stages of forest development and so on.
Our study also confirmed that canopy structure had a great effect on soil respiration, there was significant correlation between soil respiration and LAI or GF) (Table 3).
Alternatively, root biomass could be an inadequate proxy for root respiration if species differ in root distribution, morphology and chemistry [4].
