Results and Discussion Annealing of the samples implanted at RT resulted in a strong decrease of the total number of Al atoms and profile broadening both towards the surface and into the bulk (Fig.1).
The fact that not even a residual of the implantation peak was visible after Journal Title and Volume Number (to be inserted by the publisher) 2 the annealing and only slight diffusion into the bulk took place indicates that Al diffusion towards the surface and its attendant evaporation must be very fast.
Highresolution imaging and selected area diffraction have revealed that the re-crystallized layer contains 3C and 6H grains and stacking faults.
However, the lack of amorphization and the fact that most of the Al atoms were Journal Title and Volume Number (to be inserted by the publisher) 3 either trapped in precipitates [8] or occupied lattice sites resulted in significant suppression of their diffusivity.
Journal Title and Volume Number (to be inserted by the publisher) 4 Summary In conclusion, SIMS and TEM studies have revealed that redistribution of ion implanted Al in SiC during annealing reflected the amount of disorder, the type of damage and the initial state in which the Al atoms existed.

Grain is broken or split the material processing process (natural or artificial) have been a group or a batch of the shape and volume which affects chemical properties such as has some common features in the granular content group [1].
Specific algorithm as follows: (1) after the treatment of the equilibrium of nonzero gray level number N to statistics, so as to achieve effective statistics of the actual degrees series.
We set that the number of gray value is M, the gray value is ranging from 0 ~ M-1, in this range we select t as gray value, divided the image into two groups calls G0 and G1, the gray value in G0 range from 0 ~ t pixel, the gray value in G1 range from t +1 ~ M-1 pixel, we use N to represent the total number of pixels, ni represent the number of the pixel whose the gray value is i.

We researched on the observation under a microscope and found that the high APS to grain of bamboo was main attributable to vascular bundle arrangement of the rules, and effects of soil AK content on the APS were larger than AN and AP.

In the macroscopic view, the surface morphology of coating is shiny white, its colour and lustre is uniform and continuous; in the microcosmic view, coatings are compact and flat with small crystalline grains instead of many holes made by micro-arc discharge, because the silver layer has completely covered the MAO coatings which can seal the holes produced by micro-arc oxidation.
The concentration of reducing agent was certain, as the reaction processing, the number of Ag+ which can be deoxidated was decreased when the concentration of AgNO3 was larger than 5 g/L.

Later, as the improvement of drainage condition and construction method, it was gradually applied to fine grained soil.
The vibration produced by the dynamic compaction is different from the blasting or earthquake, which sums up with the following characteristics: first, the dynamic compaction vibration belongs to point source, which spreads around in the earth by the form of vibration wave, which can be divided into two types: body waves and surface waves. in the far away from the source, construction mainly affected by the Rayleigh wave, and the biggest factor of impacting environmental usually was the vertical vibration component of Rayleigh wave; Secondly, through the analysis of a large number of field measured data, we can know that the vibration wave produced by the dynamic compaction has the characteristics of distance decay faster with short duration(within 1.0 s), and its main frequency is usually at about 10 Hz, which belongs to the low frequency vibration.

Microstructure with low level porosity and very fine grain after firing process at specific temperature was obtained.
Many factors could have been selected, but it will greatly increase the number of experiment needed to be conducted and consequently, cost increase [11,18].
If the number of factors is quite high as in our case and is possible to assume that there may be low-order interactions, the data for the interaction and main effects can be obtained by running only a fraction of the factorial designed experiment.
Unlike simple design which requires a large number of experiment and no interaction between the factors, factorial design is the most complete and widely used technique where by all combinations can be tested, main and interaction effects can be easily captured and number of trials can be reduced [10,11].

Specifically, the energy conversion efficiency of the photo-electrochemical cell depends on the surface electronic structure, the charge separation and charge transport capacity, the Fermi level of the surface layer and on the number of the reactive surface sites.
Thus, the role played by difference in chemical composition between the bulk and the surface, as well as the difference in the number, the type and the distribution of defects between the bulk and the surface, must be understood in detail.
The BG of surface layer can be modified by doping, and a number of dopants were proposed and tried, such as Cr, Mo, V, Nb, N and Oxygen vacancies (VO..).
The BG in TiO2 can be lowered by doping, and in Fig 2 we summarised a number of results, including a comprehensive DFT study on C doping [2].
Fig. 6: SEM of polished and annealed polycrystalline rutile: (a)- before implantation; (b)-after 31keV Ti; and (c)-after 67keV Pt implantation at 1016at/cm2 In Fig. 6-a of the above SEM micrographs, we can clearly see the grain boundaries and the growth steps, and these features are significantly different for the implantation with Ti and with Pt.

Experiments were conducted indoor at five different Reynolds numbers (1447 ≤ Re ≤ 7237) and three different radiation intensities (430, 573, and 716 W/m2).
Furthermore, the heated air can directly be used for drying some farming product such as grain.
The corrugated channel gave higher Nusselt number than the straight channel and a higher channel height gave higher Nusselt number for the flow with the same Reynolds number [6].
The result of experimental study done in turbulent flow regime (Reynolds number of 5000 to 25,000) showed that multiple 60° V-baffle turbulator fitted on a channel provides the drastic increase in Nusselt number, friction factor, and the thermal enhancement factor values over the smooth wall channel [7].
The experiments were performed at five different air inlet velocities, i.e. 1.0 m/s, 2.0 m/s, 3.0 m/s, 4.0 m/s, and 5.0 m/s or at Reynolds number of 1447, 2895, 4342, 5790, and 7237, respectively.

The XRD results show that the addition of Nd3+ doping increases the number of SrNdFeO4 phases.
Whereas a new peak at 68.4965°, which matched with the ICDD number 01-072-0739, constitute the hexagonal crystalline system of SrFe12O19, which the dominant crystal phase as before.
XRD peaks at 32.7399°, 46.9959° and 62.6870° conform to tetragonal crystalline system of Sr3Fe2O6.64 (matched with the ICDD number 01-082-0427) with crystallographic parameters of a = b = 0.38704 nm, c=2.01763 nm, α = β = γ = 90°.
On the other hand, XRD peaks of 35.8377°, 49.6982°, and 58,4165°, which matched to ICDD number 01-076-1875, evidence a transform of the crystalline phase from hexagonal SrFe12O19 to tetragonal SrNdFeO4.
In SNF samples with higher Nd concentrations, the microstructure revealed the presence of strontium ferrite grains (dark colors) and also Nd-rich area (bright colors).
