Simulating natural ecosystem, consisting of three industries: resource productivity, processing, and reduction.
Emphasis on cost reduction and high efficiency but ignoring the harm to the environment.

Because of the reduction in current, the reactive vapor pressure on the droplet decreases before applying the secondary pulse, which leads to a reduction in the spattering.
As seen from the data of Table 1 and fig. 3, this combination of parameters gives a good result for all parameters: the formation of the bead, the spattering, the deposition rate factor.

The reduction in shrinkage, improved green and sintered densities would have beneficial effects on the material’s mechanical and microstructural properties.
The reduction of pore size and number of pores together with pores becoming more rounded can be attributed to the increasing addition of smaller particles which enhances sintering rate, allowing sooner onset of final stage sintering and improved final sintered density [1].
An improved compaction and densification study is underway that builds upon the data and methodology developed by Robertson and Schaffer [2] that will look into densification at wider range of compaction pressures and stages of sintering, respectively.

The simultaneous reduction of metal compounds and tine dispersions with the ions of this metal in the process of plating is greatly influenced by the particles size and stability, the optimal degree of dispersion and homogeneity of the fine dispersed particle system, the distance among system’s particles, the intensity of fields in the cathode vicinity, the particle’s inherent electrical conductance, and dielectric constant and so on The effective stirring of the diffusion layer’s part where the rate of stirring in v conventional baths tends to zero arises not in any ease by reducing on the cathode of the colloids and fine particles but only when the definite conditions are fulfilled [14].The considered phenomena are characterized by significant complexity, but for the rational high speed low concentrated plating solution’s selection these phenomena must be taken into account, high quality metallic deposits with desired properties being obtained [15].
So one of possible ways for the reducing at the cathode of fine dispersions and colloids of metal compounds is the direct reduction of the oxide particle: [M++O2-] + ne + H+→M + OH- Thus the order of electrochemical reaction for pH in this case must be changed.  2.
As the concentration of nickel salts is much greater than for Debye - Huckel law, the activity coefficients for sulfate solutions are approximately by an order of magnitude smaller than in the chloride ones (data from the handbooks).

(3) Where:r is the dividing circle radius, is the addendum coefficient, and the is the addendum height reduction coefficient.
It is necessary to determine the position and movement relationship between the hob and gear blank when hobbing [9]. using the data given in tables 2 and 3, the hob mounting Angle of the gear is shown in table 3.
Asymmetric modified spur gear drives: Reduction of noise, localization of contact, simulation of meshing and stress analysis [J].

Further reduction of overall reliability can be caused by usage of incorrect input data in nonlinear analysis software.
This is mainly applicable for cases when the aim of analysis and design is reduction of used materials.

Therefore, exploratory development of compositon of the electrode materials, internal resistance, stomatal aperture, size and shape in the electrode microstructure has become an important method to improve the electrode performance, including highly active catalyst for oxygen reduction, stable and efficient gas diffusion electrode and collecting way.
The global module design of battery Through calculating, the current density is determined at 50mA/cm2, and has 44 monomers and two-sided oxygen electrode which is made up of two parts, each of whose size is equal to the original data size of monomer battery, and pile series connection module design.
According to the oxygen's cathodic reduction reaction, calculate the minimum air demand, and according to the result, the appropriate draught fan and air transmitting way is determined.Air will be transmitted to the bottom of the pile through two aerofoll fans which is parallel connected, and then go through each baterry cell's surface of oxygen electrode and finally discharged from side above.

Data were presented in the form of apparent diffusion coefficients calculated from chloride concentration depth profiles after 28, 90 and 140 days exposure to 1.0 mol/1 NaCl solution.
As could be observed, SDR increases with age increasing for all mixtures except for the mixture containing GGBS as the reduction in strength decreased from about 5.3% at 3 months to about 3.0% at 12 months.
The strength deterioration ratio (SDR) increases with age for all mixtures except for the mixture containing GGBS as the reduction in strength decreased from about 5.3% at 3 months to about 3.0% at 12 months, which appreciate GGBS as the most efficient in retaining strength in marine environment. 3.

Reduction in product costs, staff and maintenance savings as well as in tool wearing, make laser processing of ceramics and glass ceramics, the most suitable working tool for machining these hard and brittle materials.
Energy cost reductions and efficiency improvement can generate more profitable methods.
Nevertheless, the gas jet can ameliorate the final roughness of the surface in contact with the sensor, avoiding recast of material over the surface and providing better thermal transfer for the gathering of data, figure 8.

It is noted that the dispersion of measured data points about calculated line is relatively small, thus substantiating the good correlation.
Figure 10 shows the example of the specimens tested at the temperature range from 293K to 1073K in compression with a 10% reduction.
Figure 11 shows the flow stress tested at each testing temperature yielding 10% reduction as a function Ni content.
