Material of lining was nondestructive detected with sound locater.
The material belongs to elastic-plastic model.
According to Mohr-Coulomb yield criterion adopted in this paper, whether the material reaches damage state is judged by internal stress state, and the material is processed by elastic model if it does not reach damage state, and otherwise it is processed in accordance with the elastic-plastic theory.

The philosophy is to transform the reinforced section into an equivalent section of a reference material [8].
(3) According to the material properties of Deng [9], Linghoff [3], Colombi [8], one can compute that k is between 2.42% and 5.60%, which means the increment of the elastic load carrying capacity was insignificant.

Fig 3 Infrared spectra of Fuxin Power Plant coal Ash 3 Mechanism of fluoride removal of coal ash The pulverized coal ash is take the silicon dioxide and the trioxide two aluminum as the principal constituent one kind of volcanic ash material, has the porous structure, to be bigger than the surface area, the surface energy to be high, and the surface has many materials and so on aluminum, silicon, has the strong adsorptive capacity.
Fig.6 Roasting time to pulverized coal ash activation effect influence 6 Conclusion (1) Based on the pulverized coal ash modified principle, uses the sodium carbonate to take the activator, raw material is cheaply easy, very economical feasible, and further launches for it by other activators provides certain basis to the pulverized coal ash modified research
(2) Has determined the modified pulverized coal ash optimum condition: Na2CO3: SiO2 mole of ratio is 0.5; Time activation optimum temperature is 900 °C; Activation time is 60min; After fluorine when gets ready the materials the quantity activates the pulverized coal ash: The waste water mass ratio is 3:25; Mixing time is 2 h

This is why multiphysical numerical analysis of transient electromagnetic and thermal fields in 3D is an actual problem of modern science and engineering.
The rotor material is steel with electric conductivity of s = 0.5×107 S×m-1 and is assumed to be linear with a magnetic permeability of m = 100m0 [2].
All mentioned electrical and thermal material constants are assumed to be independent on temperature.
In the authors’ opinion, the described technique can be used in the case of interconnected solution of the electromagnetic and thermal problems when temperature dependences of all material constants are taken into account, too.

The JIT ideal is elimination of buffers (materials or time) and the achievement of one piece flow [4].
In the last years the concept of collaboration in collaborative networks has become an important topic in science and practice.
The advantages of this concept are various: long transports can be eliminated reducing the ecologic impact; parts for installation on-site can be produced JIT and on demand; reduction of organizational and planning effort for material logistics as well as reduction of buffer stocks at the fabrication shop and on-site.

During the designing of A-380, Airbus first employed computational fluid dynamics(CFD) method to design and optimize the fuselage and eventually the drag of fuselage is reduced by about 2%; In the other hand ,more and more new materials and structures would be used, for example, the goal of designing Boeing-787 contains that: the oil consumption rate per seat should be reduced by 20%, in which about 8% is from the result of the adoption of advanced composite materials[1].
