It indicated that the layout of stiffeners is an influence factor for noise reduction for plate structures, just like that of vein layout for tree belts.
In recent years, researchers have become increasingly interested in the noise reduction.
is beam element stiffness matrix in the original coordinate system established with axle wire of the stiffener as datum line.
It indicates that the venations layout affect the noise reduction capacity for plate structures just as it does for plant leaves.

Curing the AAS cement in bittern environment leads to a reduction in the total pore volume and to a refinement of the pore structures.
Analysis of the pore size distribution data shows that AAS cement cured in the fresh water has a much higher proportion of pore sizes 700–10000 nm than that of AAS cement cured in the bittern solution, as shown in Fig. 6.
Curing the AAS cement in bittern environment leads to a reduction in the total pore volume and to a refinement of the pore structures.

Introduction The hyperspectral sensor may gain the surface image data in over a hundred narrow and neighbor wave bands.
Comparatively speaking, the wave band choice had superiority in retaining the primary data spectrum information.
Finally we have confirmed the method validity and given basic conclusion by using the OMIS data.

The article examines the impact of nanodefects on the reduction of the crystals strength.
The calculations confirm the validity of the proposed theoretical model of reduction or the hanging of the crystals strength by the atoms interaction with the external environment.
In connection with this conclusion opens the possibility of the inverse problem experimental solution, i.e. determine the numerical value of Planck's constant on the analysis basis of the ionic crystals strength tests data.
(17) Using the experimental data of A.Ioffe on σb value, λ, m, C for a dry crystal of NaCl, you will get a numerical value erg*sec, (18) which is within the margin of error differs from the Planck`s constant value established by other experimental methods.

Practically, the data of input-output table is at sector-level, furthermore, it includes both direct and indirect influences of sectors.

China’s IO tables of 1987, 1990, 1992, 1995, 1997, 2002, 2005, 2007 and 2010 are merged into 26 sectors, so that it is consistent with the energy data.
Since the IO tables of 1987, 1990, 1992 and 1995 only have “net export”, we use the import and export data at sector level of [6].

The data shows that with increasing illumination intensity, the C-V curve shifts toward a more negative bias.
The G-V data shows a reduction in amplitude of the main peak with increasing illumination intensity.
This is similar to that observed in the λ=350nm data, and is thought to be related to the changes in time constant of the dominant trapping state [7].
The data also shows that the second peak increases in amplitude with increasing photon intensity.
The data indicates that following illumination at both wavelengths, the electronic distribution within the interface changes.

Conventional processes used to cleanse chromate-bearing effluents employ methods like reverse osmosis, ion-exchange resins and chemical reduction-precipitation [1].
Appropriate controls were run simultaneously to verify Cr(VI) biosorption and reduction, if any, during experiments.
Freundlich (1926) [4] and Langmuir (1918) [5] were used for fitting the data.
To examine relationship between sorption, isotherm models are widely employed for fitting experimental data.
Experimental data obtained were found to obey basic principles underlying these models, that is, heterogeneous surface adsorption and monolayer adsorption at constant adsorption energy respectively [4,5].

However, at higher amount of wax inhibitor, the higher shear rate has less effect on WAT reduction because the inhibitor may dominate the reduction.
From the figure, the values from correlation can get along well with the experimental data.
The reason why the predicted WATs from modified Al-Roomi equation deviate from the experiment data to the extreme degrees might be due to the fact that the Al-Roomi equation takes 3 parameters into consideration, including shear rate, wax inhibitor concentration and temperature, which can increase the error in data and decrease the effectiveness of creating correlation with nonlinear regression analysis.
