The crystal structure and grain size of the various WO3 particles obtained were evaluated by X-ray Diffraction (XRD: Rigaku, Rint-2200) and Field Emission Scanning Electron Microscope (FE-SEM : Hitachi, S-4800).
Acknowledgment This research was supported by JSPS KAKENHI Grant Number 23·40224 and partially supported by HORIBA, Ltd. and National Institute for Environmental Studies, Independent Administrative Institutions of Japan.

When emissions entered into the opacimeter, the carbon oxide, nitric oxide and other grain made the light intensity weak, and the light receiver could only receive a little light.

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.

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[.

To clarify the previously obtained results with regard to the grain size composition of concrete, the program of the experimental research was developed.
Fig. 5 – The graph of “force-displacement” Fig. 6 – The graph of “force-displacement” anchoring strength of the basalt reinforcement anchoring strength of the glass fiber in the ceramsite concrete in the ceramsite concrete While conducting the tests two types of the suggested destructions were observed (slipping of the reinforcement, pull-out of the reinforcement with some part of concrete), and the average number of anchoring strength loss were 14...16 kN both for the composite and steel reinforcement.

Zeolite has a specific surface area of 1362 m2•kg-1, and grains of the following sizes: d50 = 33.031 µm and d90 = 163.123 µm.
It allows, via adjustments, a number of variables to be monitored (in addition to the estimated value of the static modulus of elasticity of the approximately linear introductory passages of the l–d diagram) that quantify material resistance against crack propagation elements in different ways.

Till now a number of experimental techniques have been attempted to improve these properties.
However, while the grain boundaries are widely claimed to be the dominant pinning centers [2], the flux pinning mechanism has not yet completely clear.
