A comparison of the concentration profiles and microstructures leads us to the conclusion that spatial gradient of binder appears due to the infiltration of metal melt into the porous matrix formed by the refractory ceramic grains.
On the contrary, all small pores between grains are filled with the binder.
Different bi-metal materials with layer thickness from 1000 down to 4 nm were investigated, number of layers achieved 5000.
Layer thickness 60 nm, number of layers is 300.

Some natural fibers that have good potency to be developed as sound absorptive material are wood, cork, kenaf, hemp, cane, cardboard, and sheep wool [4], extracted pineapple-leaf fibres [5], Arenga Pinata fibre [6], palm oil male flower [7]and combination of rice husk grain and coconut coir [8].
Moreover, a perforated panel effectively absorbs the sound energy by composing of a large number of individual Helmholtz resonators.

The average grain size was determined to be approximately 150μm.
The important deformation microstructure feature is typical dynamic recovery structure due to there exists a large number of subgrains.
In addition, there also occurs numerous Mn-containing particles and Al3(Er,Zr) precipitates in grain interior and boundaries.
(3) There exists a large number of subgrains which indicates typical dynamic recovery structure.

Introduction Concrete is the widely used number one structural material in the world.
Concrete with coconut shell as coarse aggregate and grained palm kernel as fine aggregate and compared with conventional cement concrete with stone aggregate and sand and concluded that they are suitable for light weight aggregate concrete [5].
For conventional concrete 4 numbers of 10 mm ∅-HTS bars were used.

And is also no limit to the number of input and output [1, 2].
For example, Wang Min predicted the quality of welded joints by the neural network, and experimental results also are desirable [5]; Buffa G [6] established a neural network prediction model of the weld grain; Dong Junhui[7] used an adaptive fuzzy neural network to predict mechanical properties of welded joints successfully, in which the tensile strength of welded joints, bending strength and elongation and other mechanical properties were more accurately predicted.
Mean square error function is utilized in the neural network training, as following: (2) is general error of network F, N is the number of samples, K is the number of neutral network output, is expected output; is actual network output value.
To expand the above equation and obtain derivation of , respectively, we can get: (5) (6) In these two equations, is the number of parameters to reduce performance index function in network; is weights and thresholds set whentakes the minimum.
After repeated tests, the number of neurons in hidden layer is 10.

We note that CSM is a very coarse-grained strategy for parallel circuit simulation.
At first, the number of client simulations can be largely raised.
The number of cores is specified manually for better test effects.
Numbers of outputs nodes has been listed in Table 1, too.
The numbers of nodes assigned to each core are listed in Table 3.

LSFRC was made by artifical symmetrical sprinkling the determinate number of steel fiber at the area 2cm away from the top and bottom of the panel.
The coarse aggregate(CA) was composed of the continuously graded fine stone whose grain diameter was 5~31.5mm.; the fine aggregate(FA) was composed of medium sand and coarse sand whose fineness modulus was 2.6 and sand ratio(SR) was 34%; The water(W) content and modified polyacrylonitrile(MP) content was 152 and 1.18.
In Fig 3, at the end of first phase, the ratio between circle number nA corresponding to point A and total circle number N was k1.
At the end of second phase, the ratio between circle number nB corresponding to point B and total circle number N was k2.
With the increase of the cycle number, synthetic and steel fibers among the cracks were gradually pulled out or fatigue damage, for having reached the limit of fatigue.

Page Numbers.
Do not number your paper: Tables.
Low FWHM values ​​refer to coarser grained bulk material.
The equations have to be numbered sequentially, and the number put in parentheses at the right-hand edge of the text.
Punctuation appears after the equation but before the equation number.

Introduction The nanosized crystallites are attracting a lot of interest, because many properties of the nanostructured compounds show to be anomalous when the grain diameter approaches nanometer size.
These modes involve the collective motion of large numbers of atoms which vibrational frequencies are possible to calculate using elasticity theory.
The angular number l = 0,1,2, ... measures the number of wavelengths along a circle on the surface of the particle.
These degenerate modes are labelled by the number m.

Wireless sensor network technology has the potential to reveal fine-grained, dynamic changes in monitored variables of outdoor landscape.
Especially as the development of modern agriculture, microclimate information requires more fine-grained, more precise, and more real-time.[1] The on-going technological developments in the miniaturization of electronic devices and wireless communication technology have led to emergence of wireless sensor networks (WSN) which make it is possible to acquire microclimate information more timely, accurately and conveniently.
The total sample number is about 3000 and the sampling cycle is 4 hours.
