Materials is for rational elastomer namely, accord with the hooker law
So, the actual structures poles quantity should be appropriate, set not only wastes material, and too much, too little structure construction complex wholeness, and poor to structure stability of adverse.

Brittle materials exhibit higher compressional strength than tension.
As such, investigating the fracture toughness of brittle materials can be realised through the Cracked Chevron Notched Brazilian Disc Test (CCNBD) which was suggested by Fowell [6].

Introduction Spinel ferrites are commercially important materials because of their excellent magnetic and electrical properties [1].
They have been utilized as radar absorbing materials (RAM) in various forms for many years due to their large magnetic losses and large resistivity.
Reflection losses (RL) in ferrites are related to magnetic and dielectric behavior of these materials, to ferrite-composite ratio and sample thickness.
The obtained materials are indeed uniform single cubic fcc (Fd3m) phase spinels having typical NiCuZnFe phases.

Cover contour is equipped with pressure devices VII by means of which the necessary effort for holding of material is created during the work of HAC.
At different longitudinal deformations of the carrying and cover belts it is possible relative slipping of the last on a material that negatively influence on deduction of a material by friction forces on a belt and increases wear and tear of the carrying belt.
Rubber cable belts of various producers («PXOENIX», «ContiTech» firms, Germany) giving wide range for a choice of the cover and carrying belts of highly productive high angle belt conveyors capable to transport materials at considerable height have a similar variety of elastic properties, at considerably bigger explosive effort.

On the one hand the newly-built residences are blindly following the traditional dwellings styles: Using modern materials and techniques to reproduce traditional architectural style without fully consider, resulted in the building appearances is "no ancient, no modern".
Using the modern materials, technology and reconstruction methods to express the history, you should inherit regional historic context, regional architectural, regional architectural features and the landscape pattern of the street space.
In rural reconstruction you need combine the natural with socio-cultural, respecting historical context, using the modern technology and materials to express the past, and realize the combination of regional and epochal.
On the basis of preserving the traditional culture, historical heritage and natural harmonious co-existence, we can take the science and sustainable development theory as the guideline, combining the rural reconstruction system with the new technology, new material and new equipment.

Overall, technological innovation can make the more efficient means of labor and more advanced technology methods used in the material production which is able to promote the continuous development of social productive forces.
These five subsystems are continuously related to each other and interact through the material flow, information flow, energy flow.
Thirdly, the structure and flow analysis of system dynamics of resource industry operation showed that the level of science and technology is located in the interchange of all material flow, information flow, energy flow of sustainable resource industry operation system.
