Some differences in the obtained microstructure of materials were reported [2].
It is important to estimate if the clear conclusions following from the linear model are applicable to real materials.
Namely, the profile of mode TEM00 is preferable for materials with wide range of permissible temperatures.

Because MR is a parameter related to panel material density, thus AB is the flutter boundary of the panel.
The curve CDB corresponds to Eq. (12), as the panel material density has no effect on curve CDB, it is the buckling boundary of the panel.

According to the theory of materials balance, the mathematic model of the system are established.
In our country, hydrometallurgical factories focused on increased the overall rate of mineral resources by using advanced science and technology, so the leaching rate has been some improvement.
Takes example for 6 towers in this paper, established the mathematic model of the system according to the theory of materials balance, made the level height of each tower the same in least adjust times.
According to the theory of materials balance, the mathematic model of the system is established.

Tube specimens were water tube and super-heated tube materials made from ferritic-pearlitic steel alloy grade SA-210-Gr.A1 and ferritic steel grade SA213-Gr.T22, respectively.
Materials and Methods Materials: The tube specimens used in the experiment were taken from the petrochemical industry in Thailand.
There was approximately 0.017 % and 0.009% for sulfur (S) and 0.147 % and 0.090% for carbon (C) within the tube materials of SA-213 and SA-210, respectively.
While the used tube materials of SA-210 do not have the S content on the cross-section (Fig.10).
