With the excellent insulation properties, science structure and mature technology, it widely promoted and applied in the severe cold and cold regions. 1.1 Strengthen the materials performance re-inspection of the insulation system The component materials properties and structure mode of the insulation system directly influence the energy-saving effect and durability of the external insulation engineering.
And the presence of hollow cavity structure in "spot sticky method" could provide the oxygen required for the combustion of insulation materials and the spread of flame combustion in the system. [1] The outside of the hole of door and window frames, and window panels should be heat preservation, between the door and window frame and the hole, required with the insulation material filling and sealing .
Two is to choose the small thermal conductivity materials, cutting off the heat bridge of metal frame and blade profile to make bridge-cut-off window whose effect is very good, such as aluminum alloy with the coating processing and with PVC plastic composite insulation treatment has low thermal conductivity.
If the cavity inner wall is coated with small radiation coefficient materials, the window frame materials insulation performance can be greatly improved, but the sealed air layer radiation heat transfer made of general building materials is more than 70% of the total heat transfer. [2] (2) Window glasses insulation performances should be improved Window glass is commonly used as transparent materials.

Many research activities have done to the topology optimization, and the methods unified into two subjects: one subject is structural optimization at the level of macroscopic design, the other is the study of the relation between microstructure and macroscopic behaviour of the composite materials [2].
It is the conceptual structure that indicates the materials are mainly distributed on the inner rib of the bed and on surface of the bed outline while the other inside of the bed has no materials, as shown in Fig.3(a).

The present paper proposes to assess the level of accumulated damages and approximation of material to the limiting state.
Moreover, paper [3] provides that parameters, characterizing interaction of external field with the field of eddy currents, induced in the material, are sensible both to the state of material microstructure and to the presence of macrodefects.
Density of dislocation initiated on the surface is significantly higher than inside the material [13].

Introduction Dynamic recrystallization (DRX) is an important metallurgical phenomenon during hot forming, which have great effects on microstructure and mechanical properties of materials.
Then, the R-grains grow and decrease the dislocation density in the deformed materials.

Introduction Significant progress in metallurgical technologies allows to production different grades of steels from typical ferritic steels to multiphase high-strength steels which are new materials having high mechanical properties, while retaining very good plastic properties.
Examples of this type of materials are TRIP steels currently used in the automotive industry for car body sheet in the controlled crash zone construction.
