All the data were statistically analyzed with SPSS 13.0 (SPSS for windows, version 13.0, USA), and were expressed as means and standard deviations.
Results and Discussion The degradation experiments were conducted at 25 oC in the dark, and Pys degradation was operationally defined as reduction in the extracted parent compound.

Further data analysis tools allow the determination of the location and the amplitude of the maximum strain, the global strain distribution and behavior of crack growth, which are important parameters for material testing and fracture mechanics.
A reduction of the used number of pixels allows even measurements in the several 100 kHz range.

These applications prompted increased interest in growth of high quality, large diameter single crystals with defect reduction.
The data obtained at the previous time step provide the necessary information (normal carbon flux, growth rate) for the next time step, and the computational mesh is regenerated between the steps in order to take into account the geometry modifications.

The samples were solution treated at temperature 495℃ for 30 min in an electrical resistance furnace, which was determined on the basis of literature data, and cooled with water, secondly, the samples were subjected to preaging treatment with the temperature of 120℃ for 1h.
Then compression deforming above recrystallization temperature at 450℃ was exerted on samples by universal testing machine, and the compression ratios were calculated by height reduction from 10%, 20%, 30% , 40%, 50% , 60% to 70% respectively.

Computational results The acceleration data, vehicle parts position, member stresses and deformation results were used to pinpoint the actual cause of vehicle instability and subsequent rollover.
The reduction in strength associated with the drop in barrier width can usually be compensated by additional steel reinforcement bars inside the concrete.

The reason of this excellent compatibility between dielectric and electrode layer was the control of thermal property through the reduction of thermal expansion of TiN by addition of AlN.
Each of the data point shows an average value taken over three measurements.

This local instability mainly caused by the stress concentration, which can result in a reduction of strength.
The test results can supply basis data for design the bonding method of composites circular tubes.

The impedance data were analyzed with the Equivalent Circuit (EQUIVACRT) program [16].
Increase in Cr concentration also leads to reduction of SnO2 mean grain size.

All data were collected by TDS-602data acquisition system.
In the whole process of loading test, blocks, ribs and frame destruct in turns, had the characteristic of damage-reduction

Based on the effectiveness factor and test data collected in this paper, the calculation expressions of shear strength is denoted as: (1) (2) (3) where, Vc denotes shear strength undertook by concrete, Vs denotes shear strength undertook by stirrups, and K, which functions on , is a reduction factor of the average confining stress.
