The volume fractions and grain sizes of the constituents are given in the table 1.
Conclusion The following conclusions were made based on the SEM, micro hardness and porosity analysis carried out on the samples, · The SEM images indicated the presence of large number of voids in case of composites fabricated by cold pressing and sintering process

A number of methods have been developed to synthesize W nanocrystals, including mechanical milling [6], laser irradiation [7], electron beam-induced deposition [8] and solvothermal methods [9].
The broadened peaks suggest that the WO3 sample obtained consists of small crystal grains.

The number of cycles to failure or separation was taken as fatigue life, Nf.
Moreover, the slip dislocations are easily blocked by grain boundaries or sub-boundaries so as to stagnate and accumulate, which is also a paramount factor resulting in the cyclic strain hardening.

The crystallization enthalpy of LDPE composites added 9% DE was smaller than the composite system of LDPE/POE (90/10) in the same cooling rate, the reason is that the inorganic particles was added to the system, a large number of the hetero-phasic rigid particles existed to restrict the movement of the polyethylene molecular chain, which is not conducive to the growth of the crystal [8].
DE played a role of grain refinement and heterogeneous nucleation in the LDPE composite system.

This model is actively nurture and support a number of the key production service after screening, to the producer service has self development foundation, enterprises from the separation, and then integrate and productive service enterprise.
Specifically, we can choose one or two pilot from different types of manufacturing enterprises, such as from Tangshan City black metal smelting and rolling processing industry in "Tangshan City Fengnan Xinlida Steel Pipe Co., Ltd" and from Qinhuangdao city of agricultural and sideline products processing industry in the selection of "Qinhuangdao Jinhai grain and oil industry Co., Ltd." pilot.

It can be clearly seen that the increase of temperature leads to the increment of the layer numbers of the ‘tubes’ and some tiny nano-crystalline grains even emerge on the longer ‘tube-like’ nanostructures at 1400℃, which probably indicates the improvement in the crystallinity of graphite flakes.

It has been shown that the activation of various deformation modes is related with the c/a-ratio as well as temperature, grain size, strain rate, interstitial impurities and texture [4,7-9].
Thus, the total number of elements is 10´10´10=1000.

Then the fly ash was mixed with bottom ash in a weight ratio of three to seven before crushed stones (grains approx. 30 mm in diameter) were added in a weight ratio of 33% of the fly ash and mixed to ensure drainage.
Accordingly, 11 lysimeters were prepared in total and numbered from 1 to 11.

[9] San MME, Jaime FMR, Martinez BF and Martinez MJL.Selective nixtamalization of fractions of maize grain (Zea mays L.) and their use in the preparation of instant tortilla fours analyzed using response surface methodology.

All samples presented crystallite size lower than 51 nm, which confirms the grains nanometric character.
This occurs with the increase of doping element in the ZnO matrix, increasing also the number of absorption centers; thus, increasing light absorption capacity [4].
