This process steps are as follows:
(i) Preparing the pre-alloyed powders and three-dimensional (3D) computer-aided design data
(ii) One layer of metal powder is selectively melted and solidified by laser beam
(iii) The starting plate is lowered by one layer thickness
(iv) The rake feeds a new metal powder layer
(v) Above process is repeated to produce a 3D structure.
It is very important to control the crystallographic texture which leads reduction of Young’s modulus [5].

Introduction
Energy saving and emission reduction is an important measure for thoroughly applying the scientific outlook on development and building a harmonious socialist society, energy shortage has already become a severe problem around the world, therefore, many countries have been energetically engaging in the research, development, promotion and popularization of energy-efficient appliances.
According to the meteorological data, it can be known that the temperature of tap-water in winter is t1=10℃, while in summer it is t1=28℃, and t2=50℃, thus it can be calculated as follows: In winter: =17.3℃; In summer: = 12.28℃.

Data on the protective properties of lininngs can also be acquired through electrochemical testing, mainly through impedance spectroscopy measurements.
In the range of low frequencies the spectrum for sample no. 7 (fig. 3d) after drying is situated slightly above the spectrum for the “as supplied” sample, which may be caused by the reduction in its thickness as a result of drying.

According to the data obtained, determine the most appropriate coagulant and their optimum amount were confirmed.
It can be seen that the great impact of nano-SiO2 on the turbidity of the wastewater, only adding about 0.13g of nano-SiO2 would cause reduction of the turbidity of the wastewater quickly.

This makes the production of ceramics based spinel even more expensive, despite some sintering temperature reduction.
Results and Discussion Differential scanning calorimetry data, as shown in figure 2, was used to determine the temperature of the precursor’s thermal processing.

In the Fig.6 we can see how the ultimate tensile strength changes and at the same time hardness HV10, depending on the different degrees of drawing at chosen reduction at the chosen individual draws and intermediate heat treatment.
