Thanks to its complex of valuable properties the relatively low-tonnage polyesters, such as polyethylene terephthalate-glycol (PETG), polytrimethylene terephthalate (PTT), polyethylene naphthalate (PEN), polyetheretherketone (PEEK), polyethersulfone (PES), and a number of their modifications, have been gaining widespread use [1].
Corn, grain, sugar cane, agricultural raw materials and paper wastes can be used as feedstock.

Introduction Owing to good corrosion resistance, mechanical strength, heat resistance and high formability, chromium-nickel austenitic steels have found an application in a number of industry branches.
Considering high concentration gradients, it can be noticed that diffusion at the first stage does not proceed through the grain boundaries, thus resulting in the formation of high homogeneity nitrogen layers.

The procedures are as follows: Blast the component with grain size 120/220 AL2O3 at high pressure.
The surface temperature measurement of combustor As is shown in Fig.5, color image of the standard templates and the combustor is acquired at the same time, the number shown in the picture are results from the intelligent interpretation system, the results are consistent with the values of the standard templates and manual interpretation, the error is less than 10℃.

Building of Model of factors affecting product quality(AHP-PQ) 1.1 Building of Hierarchy Model 1) Divide the factors that may affect the product quality into a certain number of hierarchies. 2) By using ISM (interpretative structural modeling method), the hierarchy model of factors effecting product quality was determined. 1.2 Structure of AHP judgment matrix Targeting an factor in upper hierarchy, relative importance of these factors associated with that was compared and quantified.
The chemical compositions are: 0.01C，0.001H，0.05O，0.01N，0.05Fe. grain size: 0.83-12.7mm，Brinell hardness: 95. 2) Design of processing technology: In order to discuss the effect of material feeding method on Chemical compositions, the following material feeding method and melting process were designed as shown in Chart 2-2.It is 60kgs per electrode.

Introduction Nano-thin film is constituted by a large number of nano-particles, and the thickness is generally less than 100nm.
Each nano-particle is a small complete grain with a few to several tens nm diameter.

The main causes of sample with good plasticity are a number of retained austenite in microstructure.
The grain size of austenite can be obviously fined, fine and dispersed alloy-carbide was precipitated which contributes to an increase of precipitation strengthening [9].

Introduction Aluminum metal matrix composites (Al MMCs) have received considerable attention over a number of years due to their excellent properties.
There are white net-like phase existed on grain boundary and fine particles phase dispersed in the matrix.

Levin M N detected grain refinement of SKTV, PDMS, PEO though a treatment of high frequency pulsed magnetic field[9-10].

Due to the vibration core tube produced internal excitation and vibration tube produces swing, it overcome the defects that the external vibration type concrete shaping machine only vibrated in the surface, dissatisfied the close-grained plate thickness requirements and floor of the load bearing ability was poor .With the core tube swinging when pulled, it had overcome the difficulties of pulling and wall collapse trombone problems.
Its input-output device and the I/O assignment and serial number were shown in Figure 3.

Currently, large researches have been done toward how to fabricate low-dimensional nanostructures with small grain size, high surface-to-volume ratio, high orientation and crystallization, and special pore structure [5].
When surfactant PEG was added to the precursor solution, a large number of tiny Zn(OH)42− and ZnO nanoparticles embedded into PEG long-chain substrate and easily grew along the long chain of PEG.
