For the oxidation of metal M in H2O giving MaOb, the global oxidation reaction can be written as follows: (5.3) Let is the differential of the number of mole of water vapour that enters the reactor, is the differential of the number of mole of water vapour consumed by oxidation and is the differential of the number of mole of hydrogen molecule produced as a result of the oxidation.
From Reaction 5.3, we see that the number of mole of H2O consumed equals the number of mole of O used to form the oxide which is the one obtained from the experiment, thus giving (5.6) where is the differential of the number of mole measured from the thermogravimetric experiment.
From Reaction 5.3, we can also see that the number of mole of H2O consumed equals the number of mole of H2 gas produced by the oxidation reaction.
In that case, the -Fe2O3/(Cr,Fe)2O3 with the thickness higher than 5 mm was found at the heart of the alloy grain while the -(Cr,Fe)2O3 close to the steel grain boundaries remained partially protective.
It can increase the oxygen permeability in the ferrite matrix or refine the oxide grain boundaries.

Abstract: Study on the effect of liquefaction mechanism on the performance of ECC, adding rubber powder mesh size effect on the performance of ECC, respectively, to 40 mesh, 60 mesh, 80 mesh and 100 orders at the same content of rubber powder and 40 mesh in different dosage on ECC compressive strength, flexural toughness was analyzed, results show that: the use of the mechanism of liquefaction of mixing rubber powder in cement based materials, with the increase of ECC number increased ductility, at the same time reduce the compressive strength is larger, rubber powder content in 12%, the comprehensive effect is ideal.
Sand: the sand grain size is 0.22~0.37mm.
a) b) Figure 2.a) Compressive strength of G1~G4 b) Compressive strength of G1‘~G4‘ Conclusion 1) the liquefaction mechanism to adjust the ECC ratio, thus liquidity or cement matrix and reducing segregation, achieve high ductility cementitious matrix and multiple cracks and thus more easily. 2) rubber powder mixed with larger mesh size, compared to the number of small can more easily achieve ECC high ductility, but the maximum carrying capacity is greatly reduced, the compressive strength has greatly decreased; with the increase of rubber powder mesh, ECC corresponding improved ductility.

In the annealed specimen, relatively large particles of Fe16N2 were formed with low number density, while in the deformed specimens, dislocation substructures due to cold rolling were disappeared by ion-implantation and fine particles were densely formed.
Number density of the �" particles in (b), cold rolled with 90 %, is obviously higher than that in (a), annealed specimen.
On the other hand, in the annealed specimen, interstitial iron atoms firstly diffuse to sinks, such as surface and grain boundaries, remaining vacancies and nitrogen atoms.

A large number of microorganisms are capable of reducing ferric iron and are widely distributed in many environments [1, 2].
Biological iron reduction has been shown to occur with a number of oxidized or partially oxidized iron compounds such as magnetite and various Fe(III)oxyhydroxides.
The samples have an average grain size diameter of about 0.1 mm and the pH(s) were circumneutral with values around 7.5.
DNA copy numbers per g dry weight obtained with qPCR quantification of 16S rRNA genes of Bacteria, Archaea and Geobacteraceae.
Conclusions Both, Archaea and Bacteria are present in similar numbers in the nickel lateritic ore deposit.

Each crystalline was then marked and the total number of crystals was counted using software.
The density of the crystals i.e. the average number of crystals per square micron was then calculated.
Variations in size and number of crystals are presented in Fig. 4.
From which we can see clearly: (1) when the Ua is less than 220V, the crystal size decreases rapidly with the increase of Ua and when the Ua is over 220V, the size of crystals increases slightly with the increase of Ua; and (2) with the increase of Ua, the crystal number increases rapidly when the Ua is less than 220V and the number decreases when the Ua is over 220V.
It is speculated that the melt-quenched titania crystallizes into grains and converts to anatase, and subsequently to rutile by virtue of local high temperature–pressure sintering in the proceeding microarc discharging.

That would increase the number of material defects and damage the compactness of the matrix and decrease the strength.
The load will directly concentrate on the inorganic particles and caused small silver grains (cracks) When the added inorganic particles are larger than the diameter of the matrix resin, which resulting in the increase of brittleness of the material and the decrease of toughness.
Round and smooth AL2O3 particles occupied a large number of dimple centers.

The alloys of titanium are few in number but have been categorized as being both a viable and attractive choice for corrosion-resistance and performance-critical applications.
The grains of the alpha phase (light in color) were well distributed through the matrix of the transformed beta phase (dark in color).
The large volume fraction of the alpha grains was predominantly nonuniform in both size and shape.
The cyclic fatigue test is the most widely used technique to establish the endurance limit of a metal by essentially determining the variation of maximum stress or stress amplitude with fatigue life quantified by the number of cycles to failure (Nf).
The alloy in the annealed condition has an alpha plus beta microstructure with the alpha grains of varying size and shape being well distributed through the transformed beta matrix. 2.

Welding is known to create tensile residual stresses, promote grain growth, recrystallisation and softening in the heat-affected zone (HAZ) [6,7], and to introduce defects that act as stress concentrations and preferential crack initiation sites.
A frequency of 1 Hz was used for all fatigue tests and the number of cycles to failure (N) was recorded for each specimen.
The number of cycles to failure (N) was recorded for each stress range (Ds) at the end of the test.
The HAZ and weld metal, characterised by large grain sizes and coarse second phase particles, were therefore found to be more prone to pitting than the base material [16].
As expected, the number of cycles to failure (N) increases with a decrease in the applied stress range (Ds).

Optical observation windows are provided on either sides of the experimental model so to take pictures of the test images and grains.
Mach numbers of 2.5 and 3.0 in the experiment should correspond to Mach numbers of 4.1 and 5.3 in flight status.
This paper only compares and analyze the data generated from numerical simulations at Mach number 2.5.
Figure 6 shows the Mach number distribution under various turbulence models.
Figure. 6 Mach number distribution of various turbulence models All turbulence model computations predict very well the development trend of the shock wave system along the tunnel.

However, danger of contention increases when the mesh is very small compared to the number of threads operating on it.
Thus it needs to elastically adjust thread number according to mesh size and the number of 3D feature points so that it can get the highest speedup.
The whole points cloud is divided into several regions according to the number of processors of the platform then assign each region to each processor.
To solve this problem, the platform is designed to elastically decide parallel grain.
From our experiments, when the number of points assigned to one processor is less than 2,000, time waste of thread operation cannot be ignored.
