When the eccentricity increases from 20mm to 60mm, the load reduction often keeps at 14%.
(3) The relationship of ultimate load capacity reduction factor and separation ratio can be described by functional relationship formula
(4)When separation height is 4mm(separation ratio is 0.68%),and eccentricity increasing from 20mm to 60mm , the load reduction often keeps at 14%, indicating that the load reduction due to core concrete separation doesn’t change in pace with the increase of the eccentricity ratio.

Fig. 7 Measurement window Experimental Result and Data Analysis The transfer function curve of each measured point is showed in Fig. 8.
Fig. 8 The transfer function curve The PolyMAX algorithm is used to analyze the modal data, and the first four set natural frequencies and damping ratio of the industrial sewing machine frame are obtained, which is shown as Table 3.
The result shows that the finite element model of the industrial sewing machine frame built in the paper is reasonable, which provides theoretical reference for vibration and noise reduction of the industrial sewing machine frame.

However, further increasing of AA charge resulted in a slow reduction of kappa number.
As shown in fig.2, similar to kraft pulping, the data for same AA but different temperature and duration fall onto same curve.
Therefore, as pulp yield without apparent reduction, a relative low Na2SO3 charge would benefit the bleaching of unbleached pulp.
The results show that all data surprisingly fall into one curve, which was different from the results of kraft pulping and conventional Soda pulping.
Moreover, the data from different AA charges have same relationships between kappa number and pulp yield.

Reductions and time between deformation and quenching were also varied in order to study the recrystallisation progress.
The conventional α (<110> // RD) / γ (<111> // ND) fibre texture was developed after plane strain compression and their intensities depend on the deformation temperature and reduction.
In order to avoid the orientation noise, the misorientations below 2° were not considered in the data post processing procedure.
The activation energies obtained are compared with the data available in literature, see Fig 1b, where all the values are higher than the one for iron self diffusion [8-13], it also can be observed that the activation energies are increase linearly with silicon addition up to approximately 4.5wt.-% where an order transformation takes place, so that implies the deformation of super structures and the formation of super dislocations.
The scattering of the data can be attributed to the interstitial alloying elements, such a Carbon, which can modify the phase diagram entirely, and also to the thermal treatment prior deformation because this one would affect the grain size, texture, homogeneity of the solute, presence of order, precipitates, etc… Fig. 1: (a) MFS as a function of temperature, strain rate and silicon concentration, (b) activation energies for different Fe Si alloys as a function of the Si content.

At the same time its sintering temperature has 100℃ reduction.
Table 2 states the tested data.
Therefore, the hardness and intensity of nano-modified cermet can be raised and the measured data verified this viewpoint.
(c) Reduction of its sintering temperature.
This results in the reduction of its sintering temperature.

In this way, geometric riblet data can be evaluated taking into consideration different roll gaps and corresponding rolling forces (see Fig. 2.2). 0 10 20 30 40 4 5 6 Time [s] Force [kN] Rolling set-up concept Parameter variation Process data handling Mill shaft Plain roll ld h0 h1 h2 A1 A0 Structured roll collar Fr2 Fr1 Variation of h0 and h1 Fr2 Fr1 Rolling process forces x y z x y z W Fig. 3.
Preliminary simulation models should allow for estimations of influences on the riblet rolling process and thus deliver reliable initial geometric data for the preparation of basic experiments and roll manufacturing.
For this reason data out of experimental results (process forces, obtained riblet geometries, real roll geometries) were used as a basis for a calibration between the FE-model and rolling process.
For preliminary form filling analyses, material data were adopted from former rolling investigations and simulations with similar material [2].
This means that results of numerical and experimental forming studies - i. e. measured contour data out of simulations and metal sheet cross sections respectively - are used as input data for fluid dynamical calculations (LES).

Data collection The targeted pulp and paper industries in this section have been taken from a previous survey that focused on the overall industrial sector in Malaysia in different regions within Peninsula Malaysia as shown in Table 1.
For example, Annual energy saving increased from 1,059,207 kWh in 10% speed reduction to 3,658,369 kWh in 60% speed reduction.
Cost benefit analysis when using variable speed drives Based on the input data of VSD incremental price in Table 6 and total annual energy saving Figure 6, the results of total annual bill saving with an average electricity price of RM 0.236/kWh and average payback period have been quantified and illustrated in Figures 8 and 9 respectively: Figure 8 Total annual bill saving (RM/year) at different speed reduction.
The results from Figure 8 show that the total annual bill savings when installing VSD in the covered industrial boilers in this study are about RM 249,973 in 10% speed reduction, RM 723,169 in 40% speed reduction and RM 863,375 in 60% speed reduction.

In electrolyte containing ammonium chloride was observed direct reduction chetyrehjadernogo emeakaroha complex, as well as recovery of oxide copper (I), formed, apparently, from single-charge complexes, appearing for due to the recovery of two-charge, due to the alkalinization of the electrode layer (Fig. 2a).
Discussion of Experimental Data For obtaining of ultradispersed powders of copper electrolyte source were: ammonium chloride solution; ammonium chloride solution containing polyvinylpyrrolidone in an amount of 20 g/ l; ammonium chloride solution containing also polyacrylamide in an amount of 40 g/l.
In an electrolyte containing ammonium chloride and polyvinylpyrrolidone, the process the formation of powder particles is accompanied by the reduction of unbound copper ions (II).
Also in the process of obtaining Cu2O is restored, which is formed in the near-electrode layer due to the partial reduction of copper (II).

(6) The coefficient is dependent on the neutron fluence, and can be determined by calibration using experimental data for surveillance specimens at fixed values of and .
Figure 2 clearly demonstrates that along with radiation hardening, the radiation-induced reduction in the level of brittle strength has a significant effect on the magnitude of the limiting fluence.
According to the data given, neglect of this effect, as it is done in many works, leads to incorrect values of the maximum permissible fluence (m-2).
In contrast, the reduction in brittle strength is associated with an increase in the number of crack nuclei generated in irradiated metal during the local yielding ahead of a macrocrack/notch.
According to the results obtained, along with radiation hardening, the radiation-induced reduction in the level of brittle strength, , has a significant effect on the service life of RPV steel.

Result and discussion 2.1 Catalyst texture property Table 1 The texture parameters of different supports and catalysts Samples Surface area (m2/g) Average pore size (nm) Total volume (cm3/g) Al2O3 190 10 0.47 CA 138.3 9.8 0.34 ZrO2 44 22.5 0.24 CZ 30.8 15.2 0.12 TiO2 20.5 35.2 0.18 CT 19.9 33.2 0.16 The texture data listed out in Table 1 shows that, the specific surface areas sequence of carrier is: Al2O3>ZrO2>TiO2, and the average pore sizes sequence is: TiO2>ZrO2>Al2O3, so we can see that the texture structures of these carriers are greatly different from each other.
Take the ratio between peak appearing area before 400℃ and the whole peak appearing area as reduction degree, data of reduction degree is as list in Table 2, from which we can see that, the reduction degree sequence of the three catalysts is: CZ>CT >CA.
From TPR result, CZ catalyst has the greatest reduction, while CA has the lowest reduction, which shows that the more the reduced cobalt is, the higher the catalyst activity will be.
The difference in CO adsorption and dissociation level on various catalysts, as well as difference in their reduction respectively, lead to differences in their activity.
The higher CO adsorption and dissociation capacity the catalysts have, the higher their activity will be; meanwhile, the higher the reduction of catalysts is, the higher catalyst activity will be.
