Experimental procedure 2.1 Raw materials Al2O3 /epoxy resin composite samples were prepared, with E44 epoxy resin as the matrix materials, different particle size of α-Al2O3 as filler, ethylenediamine as curing agent. 2.2 Test methods Preheated the epoxy resin in oven at 85℃ for 30min firstly, then added Al2O3 ceramic grains into it and mixed well.

This means the number of the rolling stages can be reduced down to a few times to get the plate to a thickness of 1mm.
Grains are SiCp,(b) eutectic Si of the as-cast strip, (c) microstructure of the ingot cast using the metal-mold.

R=2.76×10-11AρZ8/9E5/3, where r is the SiC density (g/cm3); A is the atomic weight (g), and Z is the atomic number.
Thus, other proposed earlier alternative nucleation sites for the SFs such as low angle grain boundaries [8], and localized defects in the near surface region, attributed to clusters of impurities [9] should be explored in future work.

There are several reasons ,firstly, grain size of Metakaolin almost between 1～2μm ,therefore, it’s have eminent filled function, the filled function benefit to mend the porosity and improve the pore structure and then promote strength development and reduce the shrinkage; Secondly, Metakaolin contains a lot of activated silicas and activated aluminas, when added to cement-based materials them could react with Ca(OH)2 and some hydration products rapidly and produce a mass of C-S-H gels and spiculate ettringites which could lead to a little expansion and strength increase, however, because of the activated alumina could react with the ettringite and consum eettringite step by step, that’s probably lead to the expansion fade away.
(a) sample3# (b) sample3# incorporation with 5% MS (c) sample3# incorporation with 5% MS Fig.5 SEM micrographs of PMRM Seen from Fig.5(a) and (b), with the incorporation of MS the numbers of pore and crack of PMRM significantly decreased and the mortar structure get more tight.

A large number of MD simulation studies of shear deformation have been reported.
Heino et al. studied mechanical properties and dislocation initiation in copper under shear deformation using MD simulations; they even introduced a grain boundary and an initial cut to model samples with defects [1, 2].

However, due to the limit of forming conditions, the number of synthetic materials is few.
With an increase of BaTiO3 content, the interaction and continuity of BaTiO3 grains are enhanced and then the polarization of composite become easily.

Since the surface free energy is considered to be a driving force in the sintering process, a number of sintering models have been researched for the initial stage of sintering and the resulting equations can be summarized as follows
(1) Where K1 and w are constant, D is the diffusivity, γs is the surface energy, Ω is the atomic volume, G is the particle or grain size, k is the Boltzmann's constant, T is temperature, t is sintering time and m is a constant depending on the diffusion path.

(2) where N = number of pixels contained in area of interest = optical density of individual pixels = intensity of reflected light given by individual pixels = intensity of light that would be reflected by an ideal white surface The experiment on a three-phase (air-water-LNAPL) system requires two cameras with two different band-pass filters (wavelengths λ = i and j) and the relationship between AOD and water satuaration (Sw) and LNAPL saturation (So) can be obtained as shown in Eq. (3).

The number of solid waste generated in Kuala Lumpur state in the year 2010 was recorded of 2000 tons per day [1].
There are three distinct processes that involve for the nucleation and the crystalline growth processes which are the primary recrystallization, grain growth, and secondary recrystallization.
