And the test data of load and vertical displacement was collected automatically by the computer connected with the loading device, the average time interval being 0.5seconds.
Thus it can be inferred that the “piling up” of corrosion products between the concrete cover and the core concrete zone has weakened the bonding there, resulting in partial or complete failure of the concrete cover, namely reduction of effective section of RC short-columns.
Through the experimental observation and data analysis, the conclusions have been drawn as following: First, the corrosion of stirrups in concrete specimens was uneven, as the crotch part was not corroded, the bights were corroded severely, the beeline segments were corroded relatively more slightly and uniformly, and sudden change appeared on the cross-section near the corners.
Its direct result was the reduction of stiffness of the RC short-columns, which made the deterioration form of the samples shift from ductile failure to the brittle failure.

Powder X-ray diffraction data were collected at the ShimadzuXRD-7000 diffractometer (30 min) using Cu- Ka radiation (l ~ 1.5405A°).
Research and discussion Fe-NPs were synthesized according to the known methods with some modifications using iron chloride (III) hexahydarte as a precursor and sodium borohydride as a reduction agent [10].
Schematics of Fe-NPs modification using 4-nitrobenzenediazonium tosylate The data obtained by studying the structure of the modified iron nanoparticles using 4-nitrobenzenediazonium tosylate and Fe-NPs are given in Table 1.

After reheating to 1250oC and 1800s hold, the plates were rolled to 25% reduction at 1100oC, cooled at 2 K s-1 to 875oC, where the reduction of 47% was applied.
The direct comparison method [14] was used to determine from the data the volume fraction of retained austenite.
Based on the results of optical metallography, including colour etching, and XRD data the volume fractions of phases were determined.

The SDAS reduction efficiency was higher in casting with higher cooling rate [5].
The cooling rate obtained from this study was about 180 °C/min by using the data acquisition system with a K-type thermocouple.
To ensure the accuracy of temperature setting during solution treatment and aging, the temperature of specimen was monitored during the process by using a thermocouple embedded in at least one of the specimens connecting to a data acquisition system.
Thus the reduction of Mg from the Mg3Sb2 formation should also reduce the important Mg2Si which has high effect on mechanical properties.

The treatment of ASCE10-1997[4] and DL/T5154-2002[5] are both to be reduced to the yield strength, when the ratio of width to thickness are transfinite, In order to give full play to the high strength characteristics of high strength steel, it is necessary to study the reduction of yield strength when the ratio of width to thickness are transfinite.
The position of strain foil and displacement meter see fig.1.The date of stain foil and displacement meter was automatically collected from static data acquisition instrument (TDS602).
Figure 2 The comparison between the experiment result and the values in ASCE10-1997 According to the experiment result and the analysis data, it is found out that experiment result are higher than what caculated in accordance with ASCE10-1997. the ultimate bearing capacity of the experiment value are higher than the Calculated of the “Design of Latticed Steel Transmission Structures”(ASCE10-1997), on the same section in different slenderness ratio of components, the larger slenderness ratio, the higher the ratio; while on the same slenderness ratio in different sections, the greater width-thinkness radio, the greater the ratio.

Introduction With the explosive growth of the quantity and the size of the files, stored in the Distributed File System(DFS),a large number of concurrent file access will inevitably lead to frequent metadata access, resulting in a reduction of the efficiency of DFS access.
To improve concurrency, the reduction of lock granularity and operations during lock are regarded as two effective solutions in document [5].
File metadata describes file attributes and related information, which include file ID number, access permissions, access time, modification time and the position of each file data block.
To mimic the practical environment, the experiment on System throughput uses stochastic and multi-cluster hybrid structure dataset to request a access system prototype, while load balancing experiment uses multi-cluster dataset to request system prototype to create the hot spot data. 3.2.

This induced charge separation can propagate in one of two ways: electrons and holes migrate to the surface of the bulk and react with adsorbed species in reduction/ oxidation (redox) reactions, or charge recombination occurs where no redox reactions take place as the excess energy is dissipated as heat.
Manufacturer data reports mean particle diameter of 21 nm and a surface area of (50 ± 15) m2/ g with an average anatase to rutile crystal phase ratio of 80:20.
Figure 3 Using a model based on the Gaussian function the plasmon absorption was estimated and fitted to the measured data.
Since TiO2 is not active at wavelengths above 390 nm it is not possible for it to contribute to reduction or oxidation reactions under UV blocking conditions.

The method consists in pouring a melt into the rotating rolls, crystallizing it on the roll surfaces, rolling with a predetermined reduction amount, pressing out in front of the die and squeezing out the product of the predetermined configuration and dimensions through it with drawing ratio in the range of values 10-40.

Numerical Simulation of Deep Drawing Process of Drawing Cylinder Based on Dynaform Sheng wei Yang 1, a 1Tianjin University of technology and education China a28401315@qq.com Keywords: Progressive die; drawing process; numerical simulation Abstract: In addition to the high cost and long period, the traditional design of the drawing process depends too much on empirical formulas and data.
When the radius of the punch is too small, the tensile stress rounded corners of bending will increase, which will cause the reduction the tensile strength of the dangerous section.On the other hand, when the radius of the punch is too large, the drawing sheet of overhanging portions will be widen at the beginning, which will easily produce the wrinkles.
