EDS analysis carried out on pit show spectra similar to those reported in Fig. 2 (zone 2) and in figure 3 (zone 4).They grow under the specimens surface following the bronze grain structure.
However it has been observed that even if the global patina thickness grow with the number of exposition cycles, it becomes more and more less compact.
The 0 cycle points are those of the original bronze, while the others represent the behavior after different number of cycles.

Traditional soil erosion research needs a large number of field investigation and work, which takes too much time and can’t calculate accurately in specific region, in addition, it is also difficult to obtain the dynamic change information of soil erosion.
(3) In formula(3), Sn=1-Sd/100; Sd, Si, Cl and C are content of sand grain, silt, clay and organic material.

The 180º domain walls are pinned by obstacles such as defects of the microstructure, grain boundaries, dislocations or precipitates, and need energy to move from these pinning sites.
The amplitude and the number of MBN pulses depend on the number and morphology of the obstacles and on the derivative of the magnetic field applied.

These wastes show considerable heterogeneity of grain, chemical and mineralogical composition [2].
The total number of binding sites available for sorption was calculated for Ni (II) ions = 67.57 mg.g-1 and for Mn (II) = 73.52 mg.g-1.
The number of binding sites, that were in fact occupied in the experiment with Ni(II) ions equals to 59.29 mg.g-1 and for Mn(II) to 65.58 mg.g-1.

The class including the major number of fiber length was 20-25 mm (20.5%), as shown in Fig. 4.
Water, two different grain sizes of limestone aggregates and locally available sand were also used.
A total number of twelve panels have been realized (Fig 9), varying the ordinary steel reinforcement when reinforced concrete is applied.

However and in this case, according to provisions of molecular dynamics, redistribution of atoms in an adjacent zone with increase in number of contacts is observed.
There is the creation of conditions for mechanical syneresis fluid, as well as the creation of the percolation in the form of links between the grains (refer with: Fig. 3).
In the course of the development the system undergoes a number of rheological changes.

It can be seen that for the steel corroded in pure water of 5 days, there were few corrosion products on the specimens, the surfaces of specimens were still smooth and clean, except for some pitting points, and the number of pittings did not increase with the immersion time.
There have been a number of reports on the relationship between martensite and pits.
At first, S2- ionized from H2S was attached to the surface of specimens, and pits initiated at some chemical or physical heterogeneity at the surface, such as inclusion, second phase particles, solute-segregated grain boundaries, flaws, mechanical damage, or dislocation [17, 18].

If , then the AS stores the role number into its database.
Finally, the AS sends the result number back to the issuer.

In addition all of the intensity of peaks are low, and the characteristic peaks are broadened, indicating that the samples are with low crystallinity and small grain.
(2) where F is Faraday’s number, z the differential atomic charge (for Mn2+/Mn4+, z equals 2), MMnO2 the molar weight of EMD, WMnO2 the total weight of deposited EMD, I the deposition current, t the deposition time (t equals 2 hours).
As the solution gradually penetrates into the catalyst layer and then fully contacts with the catalyst, the cathode potential is stabilized after the formation of a sufficient number of the three-phase boundaries.
