One important aspect, the reduction of
tool costs, can be achieved for example by using action media or rapid-tooling.
Principle of the robot-based forming process The track control data are generated based on the selected forming strategy and used tools.
Further factors which need to be taken into consideration are: the tool correction data due to tool geometries and a calibration of the robot systems according to the clamping situation of the workpiece.
A reduction of the edge radii led to an increase of fissures at the sheet metal edge supported by the counter tool.

The pressure effects in parent manganite compound and Ga-doped manganite are also the effects of orbital ordering reduction.
The dilution of the JT manganese ions sublattice by non-JT and non-magnetic gallium ions leads to reduction of JT distortions and spin-glass [6] or ferromagnetic ordering [1-5].

At present, the research of the steel reinforced concrete short column with double circular steel tubes is very limited, and there is only article [2] simulating it using the finite element software and studying it by revising the reduction formula of the existing steel reinforced concrete short column with single circular steel tube.
This reduction factor was obtained by fitting to finite experimental data lacking of theoretical inference and did not consider the effect of intermediate principal stress.
By substituting experimental data from article [4] into formula (19) to calculate the bearing capacities of members, the comparison between the calculation results and the experimental results is shown in the table.1 below.

Material and methods Cyclic voltammetry experiments were carried out using an Electro Analyser (Chemilink System, model EA-201) connected to a personal computer for control and data storage.
The influence of the potential scan rate (ν) on the oxidation–reduction of 1 mM DA is studied, and the results are shown in Fig. 1(b).
DA concentration show a typical linear relationship (data not shown here), with a correlation coefficient of 0.99715, and with a DA concentration between 0.25×10-3 and 1.25×10-3 M [10-16].

Besides practical applications in industry such as in catalysis, ceramics, energy storage, magnetic data storage, and ferrofluids [6,7], Fe3O4 nanoparticles have already been applied in clinical diagnosis and medicine transporters [8].
Reduction of the iron species by the organic solvents is expected, resulting in the formation of Fe3O4 nanoparticles.
All the diffraction peaks in this pattern can be assigned to a cubic spinel Fe3O4 magnetite phase with the lattice parameter of a=0.8939, corresponding well with the reported data (JCPDS: 85-1463).The strong and sharp reflection peaks suggest that the as-prepared products are well crystallized.
Whereas the oxidation potential value of ethylene glyecol increases with the elevation of pH, the potential difference between oxidation potential of en and reduction potential of metal ions is enlarged [17], facilitating the redox reaction between the ferric iron and en (Eq.1).

1.4 Data Processing
The statistical software, SPSS 13.0, was used to conduct significant difference test (p<0.05) through analysis of variance (VNOVA) on experimental data.
That is, with the reduction of the soil nutrient, the total number of microbes and the number of all kinds of microbial are reduced.
It explained that the decline of soil microorganisms’ quantity related to the reduction of nutrient, for example the organic matter.

Thermal Properties

Fig: 3 TTT-diagram of C60
The material characterization for the thermal behavior is usually implemented with Time-Temperature-Transformation (TTT) diagrams, which are difficult and expensive to measure.
The quenching of the angle brackets was done with quenching-oil W71HC from the company Durixol, who also provided the data shown in Fig. 5.
If we look at the results in Fig. 12, the measurements show a reduction of the angle due to annealing and also due to quenching, but the extent is much higher by direct quenching without any prior annealing process (-40% on average).
It seems that internal stresses have a strong effect on the angle during quenching and that a preceding reduction of stresses eases its distortion.

Reduction ratio [7, 9] under wedge rolling for the current workpiece: δ=Dd=2818=1.55 (1) As reduction ratio comes to 1<1,55<1,6 [9], the current process is possible to implement.
As a result, after the data processing, dependence between a relative slipping rate and a friction factor was obtained (Fig. 4).
