Introduction Aluminum-Lithium（Al-Li）alloys have shown potential as light-weight, high performance, metallic options for many aerospace applications, as they offer lower density, good strength and toughness, higher modulus and improved fatigue crack growth and corrosion performance when compared with other materials[1].
Experimental The as-received materials were 130 mm thick 2397 alloy in T87 conditions with the base composition (wt %) of 2.8 Cu, 1.4 Li , 0.3 Mn, 0.25 Mg, 0.12 Zr and 0.1Zn.
And the diversity of texture sorts and content which may affect the amount of activated slip systems (jmax) and the value of Schmid factor(mij), seems to be the key factor that leads to the variation of the tensile properties in different thickness layers.

The main research methods include Shape Grammar, Emotional Engineering, Cognitive Psychology, Pattern Recognition and so on.
Nagamachi [3] presented a concept named Kansei Engineering to investigate and analyze the relationships between the product style and shape elements.
Chen [4] developed this method and established a design pattern called Hybrid Kansei Engineering- Oriented Product Development.
It can be determined by the restrictive conditions such as ergonomics, Kansei Engineering, recognition of the value, etc.
It is the comprehensive impression of human sensory organs to the material.

The enterprise information construction is a complicated system engineering, industry, enterprise scale is different, different construction stage will bring different construction a detailed analysis of demand, should suit one's measures to local conditions, and to choose integrated scheme of enterprise can carry the cost of capital and technology.
Through this example we can see, the SIM method in the practical application, according to the specific situation of many functional components can be reduced (or "degenerate"), but also to achieve a very simple way. 6 Conclusion Information integration is an active field, not only driven by the engineering innovation, but also the evolution [20].

Thus, numerical methods, such as the finite element and boundary element methods, are extremely important in engineering analysis [6,7].
where κ, which is a numerical parameter, is given by κ=πϵE'3K2ƐRK (2) where, for the reduced elastic modulus E', the following relationship holds: 2E'= 1- v12E1+ 1- v22E2 (3) E1, E2, v1, and ν2 are the modulus of elasticity and Poisson's ratios of the materials of each body in contact.

The main objective of this study is to develop some fire safety education materials for such public places as government organizations and schools.
The electric roller shutters between the floors thus play a key role in influencing the fire spread, the smoke layer height and in creating the stack effect. 3.

An unlimited range of materials can be used as finishing of both the inner and the outer surfaces: paint, wallpaper, coating, fabric, etc.
If adequate materials are selected, lightweight steel drywall systems can be effectively and safely used for the envelope of the building.
