Dynamically Recrystallized Grain Size: Models and Previous Data
Models.
Previous Data.
A compilation of recrystallized grain size data on the rock materials olivine (Mg,Fe)2[SiO4] and calcite CaCO3 also revealed a close correspondence of the data with the GSSGSI domain boundary [1].
Data on Dense Polycrystalline NaCl Recrystallization Mechanisms and Mechanical Behaviour.
Clearly, the data is in better agreement with the Shimizu model.

Obtained result show a reduction in
the performance of journal bearings when the thermal effects are accounted for and, this reduction
is greater when the load capacity is significant.
Their low cost, the absence of external oil feeding and space reduction, makes them competitive compared to conventional bearings.
These studies showed a progressive reduction in the load capacity and an increase in the friction parameter and attitude angle as the permeability parameter was increased.
Experimental data used are those of the bearing of Mokhtar et al. [11] (the inlet groove is located at α = 0, R/L = 0.2878, radial clearance C = 82.5 µm, rotation speed 720 rpm, permeability K = 1.5 10-13 m²).
In the comparison between hydrodynamic and the thermo-hydrodynamic aspect, we noted significant reduction of the dimensionless pressure film, they are evident because the viscous forces decrease when the temperature increases.

This paper studies the influence on the Lateral Stiffness of Frame Structure, to provide Earthquake Fortifying Areas with reference data in the design process of filling wall.
The Influence of 0pening Rate on the Lateral Stiffness of Filling Frame.Analysis found that the stiffness reduction factor of model is decreasing as the opening rate of wall is increasing.
When the positions of openings on filling wall are different, the size of the stiffness reduction factor and the speed of change are different.
When the door opening is on the left (the side of equivalent brace), the stiffness reduction factor of model l=0.94, when the door opening is in the center, the stiffness reduction factor of model l=0.54, and such factor l=0.35 when the door opening is on the right(the corner area of equivalent brace ).
The opening rate of wall has obvious reduction effect on the stiffness of filling frame, and for the same opening rate, when the position of openings are different, the stiffness reduction effect of filling frame is also different.

In order to perform the parametric study, previously tested data was evaluated with analysis results.
Collected data is performed by Ashour et al[2].
The main variable of test data is compressive strength of concrete and volume fraction of fiber.
Because test data were illustrated with load-deflection relation, analysis method that convert displacement ductility index to curvature ductility index was used.

The results show that, the reducibility and the reduction disintegration are improved, and the mineral compositions of the sinter become reasonable with the basicity increasing.
However, no systematically fundamental data support is provided to determine the range of sinter basicity that meets the condition of Ansteel’s raw materials according to the high-temperature metallurgical properties of the sinter.
Study on the Influence of Basicity on Sinter’s Metallurgical Performance 2.1 The Influence of Basicity on Sinter’s Low-temperature Reduction Degradation and Reducibility The major experimental data and the mineral composition of sinter with different basicity are shown in Figure 1.
At the same time, the decrease in regenerative hematite ores, silicate glass phases, and pores has also brought down probability that the sinter is disintegrated due to the lattice transformation during the reduction at low temperature and finally caused the decline in sinter’s low-temperature reduction degradation index.
The main experiment data is shown in Figure 2.
