A NCD film can achieve high n-type conductivity (101-102 Ω-1cm-1) even at room temperature by nitrogen incorporation into the sp2 carbon phase in diamond grain boundaries [1].
This is consistent with the previous work; the number of minority carriers increases with decreasing the resistivity due to increasing overlap of the defect bands in NCD films [2].

Fig.1 Microstructure of Cu-Al2O3 composites after extrusion a) Cross section b) vertical section Origin, principle and application of cumulative extrusion severe plastic deformation method Cumulative extrusion severe plastic deformation method is based on Refinement of Grains by processing cold-rolled and cold-drawed.In recent years, with the development of nano-materials,large volume nano-materials is studied to get high-performance and widely application.
It has a great effect on particle distribution or the number of distribution in per unit area (volume), for the larger size of particle ,the less distribution.

With rapid crystallization of a molten metal, which is typical for high-energy techniques of materials processing, a fine-grained structure with improved physical-and-mechanical properties occurs in the strengthening zone [4-6].
Irradiation conditions: electron energy is 18 keV; energy density of the electron beam is 50 J/cm2; pulse duration is 150 microseconds; the number and the frequency of pulse repetition are 3 and 0.3 s-1.

Its purpose is "to make every grain of sand in the world can have an IP address",and to solve a number of deficiencies inherent in IPv4.

Generally, it is accepted that materials with grain dimensions less than 100 nm are called nanostructured materials[.
Thus, titania nanoscaled materials as nanopowders, nanotubes, nanowires and nanorods are object of a great number of investigations[.

Examples of irreversible traps are oxides, sulfides and carbides; reversible traps are dislocations, related to the presence of plastic strain in the steel, grain boundaries and interfaces, vacancies and cavities [1].
They established a correlation between the number of traps and the plastic strain that seems to mainly affect the total hydrogen concentration rather than the hydrostatic stress.

The pavement needs to undertake the action of a large numbers of vehicles as well as from long term severe environmental exposure.
Its crushing value for 7.8%, continuous graded aggregate well grained, specified （JTG F30-2003）.

Samasike-block of the Aral Sea was Uzbekistan within an irregular region, with a total area of 36913km2, as of now, construction of a large number of two-dimension seismic lines of the blocks, the Chinese side to deal with a new collecting aggregate 5921 km seismic line, drilling 12, Aral Sea, 1th industrial air only.
Jurassic sand-mud interbed in sea-land transition phase as the main deposition features surrounding depression in the development of fine-grained clay or mudstone, Siltstone, and the thickness of dark mudstone sediments accumulated up to 170m~330m, in the Jurassic sandstone sediments interbedded with possible local caprock and source.

Large number (more than 200) of indents was performed on each sample.
In the SEM image of the composites single nc-TiC particles dispersed at the boundaries and inside the grains of 316L steel, and irregularly dispersed aggregates of TiC appeared.
