PC3 were shown in Fig. 2 a and b, and a number of observations might be made.

As seen in the figure, while threading screw and edge dislocations, the latter forming small angle grain boundaries, were clearly detected, no basal plane dislocations were observed over the entire area.
We examined another couple of 4H-SiC boules in addition to other areas of the same boule but hardly detected basal plane dislocations in the crystal part underneath the as-grown growth front of PVT-grown 4H-SiC boules, although we found a number of basal plane dislocations in 4H-SiC substrates sliced out from the portions of the boules well below the growth front.

Introduction The studies of a number of authors indicate that the length of cutting path before wearing criterion under interrupted cutting conditions is reached is smaller by several times as compared to that under stable uninterrupted cutting conditions.
Secondly, this is reasoned by microflows in bond material of the hard-metal matrix which is in most cases intercrystalline (intercrystalline rupture occurs with coarse-grained cobalt, too).

The impact of the casting method and the production process on the final orientation and distribution of the fibers have been experimentally studied through a number of different approaches.
With respect to fine-grained UHPC, the beams usually used for cement testing of dimensions 40 x 40 x 160 mm (according to ČSN EN 196-1 [8]) were also used for 3-point bending test without notch (according to ČSN EN 12390-5 [9]).

Despite the presence of very few and small pores in the 2 mm specimens as shown in Fig. 1(a), a large number and sizes of pores are easily observed in the 6 mm and particularly in the 10 mm specimens as illustrated in Fig. 1(b) and Fig. 1(c).
Due to the fast cooling at the interface between the casting and die, the surfaces of the specimens become the location to form fine grains.

The CS base material has revealed a near-equiaxed grain comprising predominantly ferrite with small amounts of pearlite.
The morphology of the base and weld metals fractography show a ductile rupture mode characterized by a large number of dimples (Fig. 6a, 6b).

A number of bentonite-modified electrodes and electrochemical sensors have been reported [6-14].
The CdS-bentonite/ graphite composite was then taken off from the mold and dried at 70°C in an oven for 6 hr., before polished with fine grain sand paper.

The reflection of Etiquette system in the urban space is the absolute spatial hierarchical order.For example, In the《zhouli.kaogong ji》，the Royal palace is situated in the middle of the city, and become the Visual focus of the Avenue of the cities, the temple to sacrifice ancestry and the gods of land and grain were placed in the left and right of the Palace, This layout embodies the noble of monarchy3（Figure 1(left) The szu-ho-yuan in Beijing (Figure 1(right) reflects the family ritual of respect for seniority ，where older lived in the principal rooms and younger lived in the wing—room, the owner of the House lived in the inner courtyard and the servitors,who lived in the outer court.This plan reflects a rank order between owners and servitors.
Professor Zhao Bing, Wuhan University teachers, thinks that Chinese society has a gradual transited to a new period :information society since 2009, CNNI released the "China Internet development statistics report on 2009" shows that, As of 2009 June 30th China's Internet users has reached 0.338 billion people, the number of broadband Internet users to 0.32 billion, national top-level domain registrations for 12.96 million, Three indexes rank first in the world, in the same year, China mobile phone users reached 0.75 billion.

Second, the surface oxygen vacancy concentration of anatase grains is increased as the Er3+ dopant content increased, which favored the rearrangement of ions and reorganization of the structure for the rutile phase.
Excess contents of rare earth covering the surface of ZnO-TiO2 would increase the number of recombination centers and result in low photoactivity [10].

Goldmining companies face a widespread issue of fine grained and submicron gold included in the sulfide matrix of minerals, such as pyrite and arsenopyrite. [3] Various technologies for breaking down and rendering gold from sulphides are used in production to achieve high recovery rates.
A number of technologies have been introduced on an industrial scale for the full disclosure of gold in the world practice: roasting, pressure oxidative leaching, bioleaching, and ultra-fine grinding.
