The paper is a synthesis of essential data regarding the wetting conditions in aluminium – silicon carbide mixtures.
Also, by using existing data reported in the field, some parameters were calculated and interpreted.
Existing data on this compound are contradictory.
Calculations were performed using synthesized data presented by Rohatgi [37]

The adsorption kinetics was studied with the experimental data.
The data were fitted with the pseudo -first order and pseudo-second order kinetic model of Lagergren respectively.
The degradation kinetics of the three pyrethroids in coastal sediments were studied with the experimental data(Table 2).
Therefore, it could be speculated that the degradation of pyrethriod in coastal sediments is reduction reaction, and the possible pathway is shown in Fig.4(with fenpropathrin as sample): Fig.4 The possible anoxic degradation pathway of fenpropathrin in coastal sediment That is, pyrethroids are hydrolyzed at ester bond firstly, and then lose electrons to become m- phenoxyphenyl-acetonitril.

Effects of grain refinement on LCF behavior of CM247LC at 760 � were found to be reduction of data scatter and increase of minimum fatigue life.
The relatively wide band of fatigue data with CG specimens might be attributed to the anisotropy in deformation of Ni-base superalloys [2,3].
Due to anisotropic deformation characteristics, FG specimen may have relatively uniform LCF lives compared with large band of data scatter in CG specimen.

The results obtained in the analyses agree well with experimental data.
Taking tensile loading as an example, because w(f) is a monotonically decreasing function, and all other quantities in Eq. (6) are positive, the increase in the void volume fraction f results in a reduction in the deviatoric stress ijds .
The computed results will be compared with test data.
The experimental data were obtained from tensile tests conducted on an Instron 1342 material testing system.

The decreased intensities of FT-IR and 1HNMR peaks are ascribed to the scission of chain and reduction of molecular weight of PEO by irradiation.
This results are consistence with FTIR and 1HNMR data.
It is consistent with DSC data (Table 1).

Thus, the data on mechanical properties are integral values, which - although they represent general regularities - cannot make it clear to what extent mechanical properties across the sample are changed after ECAP.
Elongation (δ5) distribution across the sample: ∆ upside (Z=2.6 mm), ○ middle (Z=0.0 mm), □ downside (Z=−2.6 mm) In comparing the data of Fig. 2 and Figs. 3-5, one should note that the strength properties (tensile strength and conventional yield strength) measured in standard and small-size specimens are practically identical irrespective of the pressing route and the number of passes.
This is attributed to the size effect, which manifests itself in the decrease in plasticity with the reduction of the specimens' size [3].
The data of Figs. 3-5 show that the strength properties in the initial-state material are distributed highly uniformly, whereas elongation has considerable heterogeneity.

Overview of high steep rock slope engineering There was a rock slope engineering in Guangdong Province, the height is about 130m and length is about 302m, according to engineering survey data show that the overburden of bedrock is artificial fill soil and slope residual soil, its thickness is 2.30 ~ 8.45m, the lithology of bedrock are: shale, sandstone, geological conditions is complex, rock boundaries, fractures, weak structural plane are staggered, and there are another two through fractures F1 and F2, F1is major fracture, trending toward is NE9°, the tendency is NW279°, the average angle is 78°; F2 fault: trending toward is NW316°, the tendency is SW226°, dip 78°. 3D modeling of high steep rock slope Midas GTS is an excellent finite element method (FEM) 3D numerical simulation software in engineering field which has fast and intuitive three dimensional modeling, rapid and very powerful ability in mesh generation, professional geotechnical analysis capabilities and intuitive analysis
According to the water table for each drill hole sectional view of survey data, a cross section water line is drawn, while the groundwater pressure is as external load, directly on the slope structure, it is in order to achieve a common effect of rainfall and the water table.
Earthquake time curve Using the strength reduction method, rock slope is three dimensional analyzed under its own weight, heavy rainfall, earthquake three conditions effect, obtained the safety factor, the maximum shear strain (potential slip surface) of slope, shown in Figure 6~10.
Verified by actual monitoring data show that the calculated results are accordance with reality.

Pareto Plot is a graph that shows the effect of a factor or set of factors on a response by plotting the relationship as determined by regression analysis of the data set.
Then Isight is used to write the input data and obtain the output data.
The following conclusions can be drawn from the current work: To practically realize the lightweight design for a car body frame, the reduction of design variables is a wise choice.
