Beside such methods as powder metallurgy, rapid cooling, mechanical alloying and other it is more frequently used manner of convenient obtaining of materials practically on each type of substrate.
In classic awareness the electrodeposition process of metallic materials on cathode is connected between other with the following factors: (i) nature of co-deposited metals and difference in their atomic radii, (ii) kind and state of the substrate structure, (iii) difference in equilibrium potentials of the deposited metals being the reason for overpolarization and depolarization of discharge of metal ions, (iv) rate of co-discharge process of the metal ions dependent on the electrolyte type, its temperature, pH and cathodic current density, and (v) interaction of the metal ions and another ions or solid particles existing in solution during the electrolytic process (underpotential phenomena, induced discharge, adsorption phenomena of the ions, chemical reactions of reduction and oxidation) [1-7].
Contemporary electrochemistry more frequently utilizes the electrodeposition process for production of new materials with concrete functional properties or materials being suitable for obtaining these properties after simple thermo-chemical treatments.
This results from the fact that technologies of the electrolytic production of composite materials possess many operating parameters enabling the controlled affecting on the structure of the obtained material and in consequence on their properties.

The dynamic PSO modifies the inertia weight, learning coefficients and two independent random sequences which affect the convergence capability and solution quality, in order to improve the performance of the standard PSO algorithm.
While the motor parameters change with the external factors, these changes are not only related to motor temperature, but also related to motor operating condition.
For example, RLS algorithm is complex and the identification result accuracy is lower; EKF algorithm design and the objective function are difficult to determine, the operating time is longer, and easily affected by noise; MRAS can only identify rotor time constant or rotor resistance In recent years, many scholars apply intelligent optimization algorithm to asynchronous motor parameter identification.

A coaxial connector is used for their mechanical connection.

Combining the domestic and international development situation of space intelligent manufacturing, the application status quo and the demand and application model of China's future manned space field, it is very important to propose a development path suitable for China's technology and economic status. 1 Establish a material system suitable for space-in-orbit manufacturing Material properties are a key factor affecting the performance of additive manufacturing components, requiring the ability to systematically comb the inherent properties of space-printable materials, providing an original data foundation for the design and performance analysis of space-built components or structures.
This may be related to factors such as the aging of materials in space and the deviation of the printer's three-axis calibration values. 3 Space 3D printing development path analysis (1) Standard system construction In the American ASTM and ISO standards, the standards for additive manufacturing technology have been collated and stipulated.
New physical models need to be studied to predict the material properties of the additive manufacturing process and to help optimize the material composition.
An understanding of the basic physical properties of a material can establish a predictive model of material performance, enabling designers, engineers, and users to estimate the functional properties of the manufactured product during design to adjust the design to achieve the desired results.
At the same time, in the additive manufacturing, the axial or machine direction may generate thermal stress in the component, thereby affecting the manufacturing precision of the final product.

These main factors that restrict high-speed motor to large power direction are the small volume, large loss, cooling difficulties, and mechanical properties higher.
If the stator slots of ventilation in the area is very small, it is to say radial ventilation too narrow or slot too big will lead to air volume can't come to duct and air gap place, which will seriously affect the rotor heat dissipation.
So it was unreasonable of thinking about fluid velocity equal before in the ventilation of the ditch. 3) If the radial ventilation too narrow, it will lead to the cold air can't come to axial duct and air gap, which will seriously affect the rotor heat dissipation.

High temperature mechanical properties of due to improving significantly longitudinal plasticity, creep strength, creep rupture life and thermal fatigue property of superalloy [3-4].
High temperature gradient can increase the cooling rate during directional solidification, which refine solidification structure, decrease composition segregation and improve high temperature mechanical properties of casts [5-8].
The mechanical properties of superalloy with different structure scales, which were obtained under directional solidification with different thermal gradient, were investigated by many domestic and foreign scholars.
The effect of temperature gradient on the mechanical properties of superalloy can’t be completely reflected because of the lower solidification rate for the previous researches.
The mechanical properties of directionally solidified superalloy are affected by the dendrite arm spacing, γ' precipitate, micro-segregation as well as the crystallographic orientation.

In addition the lenses’ quality is affected by the process control.
Many earlier researchers focused on the improvement of the injection process parameters to the surface geometry or the mechanical properties of lenses.

While a large number of experiment show that the temperature field of Friction Stir Welding is a continuous dynamic process, the distribution of the temperature field directly affects the plastic flow of the weld metal, and then affecting the weld shaping and the mechanical properties of welded joints【2,3】.Especially, the problem is more prominent for welding the high melting point material such as the low carbon steel.Therefore, it is important for optimizing the welding process to study the low-carbon steel stir welding temperature field changes in the friction stir welding process.On the basis of theoretical analysis, using finite element software ANSYS simulate and analysis the temperature of entering into the quasi-steady in the friction stir weld process and the variation law of the feature point’s temperature.It will get the variation law of temperature in the the friction stir weld process,and thus lay the foundation for optimizing the welding process parameters and improve
