Introduction Gas-solid heterogeneous reactions take place in a large number of domains, whether at the natural state or at industrial scale.
Due to its nature, on the sulfide phase, diffusion can occur by two ways inside the ZnS phase, in the bulk through solid-state diffusion via point defects and/or through the grain boundaries between ZnS particles.
(4) where nv is the number of vacancy defects, N the number of lattice sites in the crystal, T the temperature, k the Boltzmann constant and ΔHf the formation energy of one Schottky defect (corresponding to the pair formed by one anion and one cation defect).
XRD diffractograms (Fig. 2) correspond in both cases to zinc oxide wurtzite phase (ICDD file number 00-036-1451).

In the RE modified alloy with a higher cooling rate (~1000K/s), the number of the branches on RE modified eutectic Si increased, and the morphology of eutectic S was modified to coral-like structure.
A large number of eutectic Si particles distribute on α-Al matrix.
In RE modified alloy, the number of the branches on eutectic Si increase, and the morphology of eutectic Si is modified to a coral-like structure.
In the RE modified alloy with a higer cooling rate (~1000K/s), the number of the branches on RE modified eutectic Si increase, and the morphology of eutectic Si is modified to coral-like structure
Effects of Al−Ti−B−RE grain refiner on microstructure and mechanical properties of Al−7.0Si−0.55Mg alloy[J].

EXAFS measurements show astonishingly low coordination numbers caused by high concentrations of Schottky defects (Table 1) corresponding perfectly with density values obtained by He-pycnometry (Table 2).

Results The results obtained in the wear tests are presented in figure 2 and show that the non inserted ductile iron presents a loss of weight (measured by the slope of the curve of the weight loss versus number of wheel revolutions) approximately fifty percent higher than the inserted material.
Fig. 2 - Weight loss versus number of wheel revolutions for non inserted ductile iron (gray triangles), inserted ductile iron in the as-cast state (white balls) and inserted ductile iron with a rectified surface (black balls).
The non inserted ductile iron test piece surface has shown a uniform waviness with a wavelength around half a millimeter, equal to the average diameter of the sand grains, as one may see in see figure 3a); at higher magnification, much finer wear marks have been observed, as presented in figure 3b).
In fact, as presented in previous work [2], the base metal shows a hardness number close to 250 VHN/4.9N, whilst the hardness of the inserted material is in the range from 400 to 500 VHN/4.9N along 2.5 mm; this higher hardness is surely coresponsible for the less intense abrasive action during the wear test.

Diffusion bonding tests were carried out in a vacuum environment with 1.3 × 10-2Pa.[8,9,10] Table.1 connecting forming processing parameter of three kinds of samples Samples number Upper limit Temp.
The diffusion layer is a multi-phase organization, and layer thickness, which has a great influence on joint strength, augments with the increasing temperature and cycling numbers.
Fracture is of mixed type and dimply pit and cleavage plane exist in the local area, which show that the joint has certain toughness. 25-steel side TC4 side 25-steel side TC4 side Fig.5 fracture morphology of tensile sample At the side of TC4, because of the joint bearing tensile stress and the limited slip system, strain will occur between the lath interface of residual β grain and refinement α phase in the welding seam.
The atomic radius, crystal lattice type, lattice constants and atomic number of the outer electron of Al is close to Fe, which is beneficial for metal connection and helpful to the conduct of diffusion bonding.

Their findings suggested that there are a fair number of patients who have “subclinical,” low-grade stent fracture that remains clinically silent.

On March, 2007, the Postal Saving Bank of China established, by taking full advantadge of the location and large number of branches, this bank expaned its agricultural business, strived to develop petty loan, and at the same time, gradually searched for rural area fianancial institution wholesale loans and carried out pattern of loans of group of banks to expand the support of agriculture.
In the end of 2008, there are 2000 rural companies acquired the qualification to be listed, however, there were only 59 existed listed agriculture, livestock and aquatic companies, only accounted for 5% of A-shares market, the listed number of stocks only made up 3.74% of A-shares market.
Chinese rural financial market, at present, although the category and amount of formal rural finanical institutions have increased, the trend of rural credit investment is decreasing as the result of the driven of commercial interests that cause rural financial institutions take deposits in the vast rural areas, with the inline tranfered capital and urban branches transferring a large numbers of capital to urban area by credit and loan and stock jobbery.
In the middle the agriculture is the body of rural economy which based on producing grain.

In fact, the mass of each ball and the number of the balls is determinate due to the same condition of b/r in the experiments.
The mass and the number of balls are ambivalent factors, because if the mass of each ball increases, the number of the balls must decrease.
But, steel slag milled by C ball for 3 h is finer-grained than A ball under the same conditions.

Fig.1 Schematic diagram of overall structure At present, Nanchang traffic problems are: road construction is not perfect 45.7%; peak personnel flow is too large 51.4% bus system is not perfect; 42.8%. 51.4% of the people think the present Nanchang Nanchang city traffic situation is not good, there is the Development Zone City traffic problems: the traffic lights to set remains to be improved in 54.3%. 68.6% some people think that the number of Nanchang city traffic lights on the road too little, some junctions often traffic jam because of lack of traffic lights. 68.6% think that the road ditch is not wide enough too crowded, lane number is too small, the need to expand.
Nanchang as a piece of fruit production base, excellent transport links can make Nanchang fruit the fresh shipped to the field, and also make a single agricultural structure based on grain production to diversify the structure transformation.
Convenient transportation network gave birth to a large number of logistics companies, the goods shipped from all over the city at the remote can be reached in a short period of time.The logistics structure qualitative change.
