Introduction Synchrotron X-ray topography (SXRT) is a non-destructive technique that images structural defects (dislocations, stacking faults, grain boundaries, etc.) in bulk crystals, epitaxial films and wafers fabricated for electronic devices [1-5].

The tests were experimented by the DG-49B well. it is only one well of porous geothermal reinjecting in Dagang District, it is deep as 1892m, water temperature is 62 degrees, as well as the initial flow rate is 85m3/h, the static water level is embedding at 77m, the essence is geothermal fluid compressed in the subsurface by reinjecting, it depends on strata lithology of thermal aquifers such as the range of rock grain size, the porosity and the permeability [2].

When speed increases, the number of grains involved in processing increases per unit time, thus improving the material removal rate, but when the speed reaches a certain value, the centrifugal force also increases, it results in accelerating the escape of particles, so that the movement distance of a single particle diminishes, the retention time is shorter, so the roughness of the workpiece increases, the material removal rate decreases.

The result was shown in Table.4 Table 4 Change of Form factor F in test Time t/h Number 0 24 48 72 V17XW-1 0.79 0.74 0.77 0.79 V17XW-2 0.79 0.83 0.87 0.87 V19XW-1 0.79 0.77 0.77 0.78 V19XW-2 0.78 0.84 0.86 0.89 V21XW-1 0.78 0.77 0.77 0.76 V21XW-2 0.77 0.83 0.86 0.89 V24XW-1 0.78 0.76 0.77 0.77 V24XW-2 0.79 0.83 0.85 0.88 The result of Table 4 shows that, the form factor F of basalt is nearly the same in the first 24 hours, with the initial value is evenly from 0.74 to 0.79, while the final value is from 0.83 to 0.89 in last 36 hours.

P3OT may raise the number of exited electrons to generate photocurrent.
The microstructure contains small grains separated by voids.

Despite the performance of the different crystal structure MnO2 is big difference, its properties are also strongly dependent on the grain size and morphology, particularly the nanostructure.
It can be seen that the layer folded δ-MnO2 microspheres contained a great number of water molecules, while the water content in α-MnO2 was far lower than that in δ-MnO2 sample, which further indicated that the crystal structure of MnO2 had a close relation with bound water. δ-MnO2 contained more bound water and inter-layer K+ due to its large layer interval; in contrast, the amount of bound water in α-MnO2 in tunnel structure was much lower than that in δ-MnO2.

They are made of fine grain tungsten carbide and supplied by Van Hoorn Hardmetaal BV; they are further coated with diamond via chemical vapour deposition (CVD) by Oerlikon Balzers AG, to protect the tools against abrasive wear.

After supporting, it was sintered either in the furnace at temperatures up to 1200 oC, or under the action of laser radiation (excimer KrF laser, λKrF=248 nm, τ=20 ns, ν=1-10 Hz, power density 10 -400 mJ/cm2, number of pulses 10- 6000) or electron beam (electron energy 2.4 MeV, pulses frequency 1 - 25 Hz).
YSZ layer (Fig. 2b) is comprised of crystalline faceted grains with typical sizes ~ 1 micron intergrown into a dense layer without any cracks.

Here, is positive constant, g is strength of anisotropy, k is anisotropy mode, q0 is angle between preferred growth direction and x-axis, is amplitude of fluctuations and is random number distributed uniformly in the interval [-0.5, 0.5].

There are a number of different mass finishing processes.
The cullet is then sieved and subsequently graded in a manner similar to that for abrasive grinding grains.
