Construction of groundwater reservoir, increasing the number of the reservoir water level fluctuation under mainland, causing the soil compression and rebound repeatedly, and producing the irreversible plastic deformation.
Porosity reduction rate with the variation of the number of cycles could reflect the impact of groundwater level lifting on the capacity of groundwater reservoir.
The microscopic mechanism of the above-mentioned law: the sand is granulated structure composed by a single grain structure which has little contact between particles.

Introduction Soybean protein hydrolysis process because of protease often cause protein hydrolysate of browning, because the soybean protein hydrolysis into peptide process often to be accompanied by a large number of pigment material formation, formation of oligopeptides mixture present a dark brown and dark brown.
But, activated carbon to add the more quantity by adsorption of protein are also more, resulting in a large number of protein loss, bring the economic benefit of the loss.

Due to very close atomic radius, the lattice type, lattice constants and atomic number of outer electrons for copper and iron [12], copper have good metallurgical compatibility with steel during bonding process.
From Fig.1(c), a curly diffusion layer can be obviously seen, and there are tiny cracks along grain boundary of CuMn20 alloy.
Physical and chemical properties of four elements Element Melting point (℃) Density (g·cm-3) Atomic number Atomic radius (10-10m) electronegativity Binding energy (kJ/mol) Crystal structure Cu 1083 8.96 29 0.128 1.90 336 fcc Fe 1535 7.86 26 0.127 1.83 413 α-bcc γ-fcc Mn 1244 7.21 25 0.131 1.55 282 α/δ-bcc γ-fcc Ni 1455 8.908 28 0.124 1.91 428 fcc As seen from Table 1, Fe has the highest melting point and much larger binding energy than that of Cu and Mn, indicating that Fe diffusion activation energy is far above that of Cu and Mn.

Microstructure observation The number in figure 5 means the position in the micrograph where we investigated the microstructure of deformed specimen.
"Observation point (from 1-4)" in Figure 7 means the position of micrographs were taken from the number in Figure 5.
On the other hand, it is thought that complete dynamic recrystallization is not obtained inside of the material because the processing time is not sufficient, only with the magnitude of several seconds, and the unrecrystallized grain etc. remain, and is thought that bigger flow stress was shown by the influence of the high-velocity deformation and the crystalline texture for 100mm/min at the compression speed.

The efficiency of a dispersed concrete reinforcement with the help of a polymeric micro-fiber is a variable value defined by a number of parameters: fiber length and diameter, polymer modulus of elasticity as well as the number of fibers in a concrete mixture volume unit.

From Fig. 1(a), the platelets are hexagonal shape grains.
Large number of α-Al2O3 platelets is developed at the interface between the glass.
A large number of small particles can be observed on the surface of platelets, further verifying the growth mechanism of Ostwald Ripening mechanism.

Moreover, based on the two-film theory and the crystal theory, Englezos [7] put forward that methane hydrate crystal growth rate is proportional to the supersaturation of methane in the water and surface area of methane hydrate grain.
· Assuming there is a large number of free water in the inside surface of CO2 hydrate film, and CO2 is reacted with free water in the film-water interface, and the spread position is the inner surface of the hydrate film
· In the gas-liquid interface, below the hydrate film is water phase; the heat released by hydration reaction can be directly transferred to the aqueous solution and can be taken away by coolant water, so the heat of the CO2 hydration reaction can be ignored Based on the above assumptions, the growth process of CO2 hydrate in the gas-liquid interface can be simplified that CO2 gas spreads along the axial of the reactor in the inner surface of the "hydrate film" with a large number of free water, and is reacted with the free water, the main reaction front is in the inner surface of porous "hydrate films".

The numerical modelling is tested by experimental work on a number of compositional variants of the newly-developed SCA425+ superalloy, which contains appreciable quantities of Cr.
In order to confirm whether the cast bar contains any grain defect, the bars were macro etched using HCl + 5~10 vol.% H2O2 solution.

Introduction Advanced ceramics were used for structural materials and functional materials with a number of excellent capabilities.
There were some whole grains on drilled surface of ZrO2/CePO4.

By model and number analysis, rigid polyurethane foam have a good anti- vibrate, shock isolation function.
Based on experiment research on explode function of the sand and saw end, wheat hull...etc., Hongjun Gu etc. [6] suggested that grain of material should flap panel layer structure in actually application.
