It has reported that higher coating thickness increased the grain size and the roughness of the coating [4].
By moving faster, the number of sputtered atom that deposited on a the substrate surface also reduced.

The factor number of test was 5 and level figure was 7, test factors and levels of U7 (75) uniform design table were chosen according to test requirements in table1, and uniform test scheme and experimental results were listed in table 2.
The results showed that particle shape of sample 2, 6, and 7 was irregular, particle surface adsorbed grains with only about 5nm , and had a certain degree of particle reunion.

Table 2 Technical indexes of different dimension aggregate and mineral material Aggregate grain diameter Bulk relative density（g·cm-3） Apparent relative density（g·cm-3） Water absorption (%) Crushing value （%） L.A.abrasion value（%） Adhesivity level 19～31.5mm 2.679 2.735 0.77 -- 6.9 third level 9.5～19mm 2.667 2.740 1.00 18.6 8.2 -- 2.36～9.5mm 2.650 2.756 1.45 -- 10.5 -- 0～2.36mm （limestone） 2.719 2.762 0.57 -- -- -- 0～2.36mm （granite） 2.674 2.726 0.71 Mineral powder -- 2.758 -- -- -- -- The testing results of crushing value and L.A. abrasion value showed that granite aggregate had the high strength and strong abrasion resistance property, the asphalt pavement build by this material had the character that slowly-reducing of frictional coefficient which was benefit for the traffic safety, but the adhesivity of granite and asphalt was weak.
When describing the stripping inflection point, it is the number of passes at which the deformation of the sample is the result of moisture damage and not rutting alone.

Using the contrast instead of the amplitude, setting the threshold value for the contrast, we measured average grain size by the linear intercept method (about 150 particles each) with results showing in Table 2.
The fracture toughness is correlated with the α2 and silicides in a mean of fraction, number as well as size.

Surrounding areas of Luyang Lake Wetland are densely populated, and most of the lands of the lake areas are used for growing grain, cotton or the construction of salt pans, alkali pools and nitrate pools, resulting in the natural water area of the wetland has been reduced.
The flexible dam of the plant is to plant a certain number of sea buckthorn trees with fixed plant space and line distance in the ditch or main river canals.

TiC was more or less distributed along grain boundary, resulting in a network distribution in the inner layer.
In addition, TiO2 distributed uniformly in the microstructure and a small number of porosities were seen in the outer layer.

In order to eliminate the defects, a number of wet chemical synthesis techniques have been developed.
Li, Grain-size effect on the dielectric properties of Bi0.5Na0.5TiO3, Chin.

Around the depression, there develop a great number of alluvial fans and vast alluvial plains form in the center of the depression.
In the late Ek1 and lower Es4, the areas of fluvial systems enlarge, covering the most parts of the depression and the grain size of sediments become coarse.

It is clear from Fig. 3 that AgNi and AgFe contact materials can be manufactured well by RCM and that the grain size of the primary Ag phase and even the Ni and Fe particle sizes are well comparable to those of AgNi and AgFe alloys produced by powder extrusion.
Representative for a large number of manufactured rivets, it reveals no cracking during final cold deformation in AgNi and AgFe contact materials.

The dimension of the silicon wafer reaches to 300mm and the slicing number is 2.5 times to 200mm.
The kerf losses and is greater than fixed abrasive multi-wire saw under the same grain size of the abrasive.
