As additives organic substances of different structure usually are used.
When the entire structure is completely destroyed, there is a minimum in viscosity.
Furthermore, the process of their adsorption on the surface of a larger structures is possible.

So arouse universal attention in natural science and social science, it has been widely used in mathematics, physics, chemistry, material science, biology and medicine, geological and astronomy, geography, earthquakes and computer science, etc.
It has the irregular forms, fine structures, self-similarity partial and the whole and dimension of non- integral, and the formation of the iteration, etc.
The graphic in the world is diversity, colorful, and most graphics are in complex structure, graphics in simple and regular structure are rare, except the quadrangular and triangular spaces that drawn by Euclid etc, most graphics are hard to draw by hand-painted, fractal graph is the one [2].

The ablation mechanisms of the C/C-ZrC-SiC composites were supposed to be the synergistic effects of thermo-chemistry ablation (oxidation and sublimation) and mechanical erosion.
Because of these characteristics, the C/C composite was used successfully as the thermal structure materials in aerospace indurstry[1].
Fig.2 Contrast of ablation rate between C/C-ZrC -SiC and C/C The ablation mechanism of C/C-ZrC-SiC composites Fig.3 shows the structure of the C/C-ZrC-SiC specimen was dense, compared to the C/C specimen.

Thus were obtained catalytic supports with the composition Ce1-xCuxO2 and the effect caused by doped element in the structure of the CeO2 was evaluated.
The results showed that the doped element (Cu) was not completely incorporated in the CeO2 structure and was evidenced that how much larger the quantity of Cu larger maid the disorder of the atomic structure of the obtained material.
The analyzed supports present mesoporous nature structure.
The proportion of each reagent in the mixture obeyed the concepts of the chemistry of propellants so as to favor the oxidizer/fuel = 1 relation [9].
Thus, it can be stated that the structure of cerium dioxide has become much more amorphous the higher the concentration of copper used in dopping.

Different coarse-grained structures were obtained by annealing at temperatures ranging from 540 to 1300 o C.
Subsequently, severe plastic deformation by high-pressure torsion at room temperature, produced the nanocrystalline structure.
%Co-30%Cr alloy by high-pressure torsion results in a partial transformation of the initial phases and the formation of a nanocrystalline structure [5].
%Co-30%Cr alloy in severely deformed condition and for different samples having coarse grained structure produced by annealing at different temperatures.

Crystal Structure of the Compound Sc1.33Pd3Al8 with Layers of R Atoms and Al3 Triangles Vasyl Stotskyia, Svitlana Pukasb, and Roman Gladyshevskii c Department of Inorganic Chemistry, Ivan Franko National University of Lviv, Kyryla i Mefodiya St. 6, 79005 Lviv, Ukraine avasylchemscientist@gmail.com, bsvitlana.pukas@lnu.edu.ua, croman.gladyshevskii@lnu.edu.ua Keywords: scandium, palladium, aluminum, X-ray powder diffraction, ternary compound, crystal structure.
Together with the structure types Tb0.67PdAl3, Y2Co3Ga9, Sc0.67Fe2Si5, Er4Pt9Al24, Yb0.67Ni2Al6, and ErNi3Al9, the structure type Gd1.33Pt3Al8 forms a family of intergrowth structures built up of three kinds of similar monoatomic layer.
The crystal structures of these aluminides belong to 34 different structure types of 29 different stoichiometries.
Their crystal structures were refined on X-ray single-crystal diffraction data; for the compound Er1.33Pt3Al8 the average structure was determined.
The structure drawings were made with the program ATOMS [12].

The composition, phase structure, particle size, absorbance spectrum, and photocatalytic performance of samples were characterized by XRD, nano laser particle size analyzer, ultraviolet-visible spectrophotometer.
It can be concluded that the nano-structures of S-doped TiO2 was not changed.

Co-doped ZnO nano powders exhibit wurtzite (hexagonal) structure.
Co2+ enters into ZnO crystal structure and substitutes for Zn2+.
The phase structure of samples was characterized by XRD.
They belong to a hexagonal wurtzite structure.

The structure, morphology and photoluminescence of as-synthesized product were characterized.
While after thermal treatment, the hexagonal structure was disappeared to transform into the monoclinic structure of the LaPO4 in P21/n(14) space group (JCPDS file 32-0493), and no additional peaks for other phases associated with the doped component can be detected, indicating that the final product are of pure monoclinic structure and rare-earth ions have been uniformly incorporated into the host lattice of LaPO4.
This indicates that the structure and crystallinity can be effectively controlled by the added molten salt.
Conclusions Monoclinic structure of the LaPO4:Eu nanocrystals were synthesized by molten salt method.
