Introduction
At present, since it has higher strength and higher elastic modulus, as a result of "C" existing in covalent form and distributing along the axial direction of crystal lattice, carbon fiber has been used widely as new materials[1].
Carbon fiber possesses the following advantages: The strength is 4 times and 7 times of that of steel and lead respectively, while its specific strength (the ratio of material strength to density ) is 16 times and 12 times of that of steel and lead respectively; Its anti-deformation capability is 3 times of that of steel; Its has the character of high temperature resistance (at 600 °C the property remains unchanged, while the strength of non-metallic materials, such as nylon and glass fiber, decreased greatly as the temperature increased.) and low temperature resistance(At -180°C, it is still flexible); And it has excellent corrosion resistance, with high fatigue strength [2].
The testing result is satisfied if the strain loss is between 4—7 after holding the load for 48 hours, when the tension test is finished. 1.4 Test materials The strength design of specimen’s concrete is according to C40; The beam’s main steel bars shall be grade one/ I grade; The reinforced material, which is CFS2 - 3. 55 -220 – 017 Type Carbonfiber-reinforced Plastics (CFRP), is bought from Shang Hai Yichang Carbon Fibre Material Co.
The main performance of the cementing material is shown in Table 1-1.

With the electrolytic etching time further increasing to 10min, a discontinuous coating composed of spherical materials with featureless morphology was deposited on the substrate surface (Fig. 1f).
Finally as the electrolytic etching time increases to 10min, the most obviously change in spectrum Fig. 2f is disappearance of the peaks around 1140 and 1488 cm-1.But the board and strong band peak centered at around 1580 cm-1 became slightly pronounced, corresponding to highly disordered carbon atoms in sp2 hybridization [10].It indicates that these spherical materials in fig.1f are composed of non-diamond carbon phased [11].

The process of metal jet formation and detonation of the ERA involve the interaction between materials with high density ratio, so the density approximation is a key component in the SPH particle approximation of the governing equations.
Reference [10] presents the concept of “Compositing Density” to deal with the interaction between materials with different density and introduce it into the numerical simulation of underwater explosion.
Based on this work, the concept of “Generalized Density Approximation”, which is defined as (2), is presented and applied in the SPH discretization of continuity equation during the interaction between materials with high density ratio.
Then the error caused by the discontinuous density between different materials can be obviously reduced and the mass conservation is ensured
The material of metal jet is set as copper in the paper, so is defined as [11] in the simulation.

It also pointes out that the combination of the methods of symbol and metaphor , technology and materials of modern architecture, a further exploration of traditional culture symbols, cultural energy stimulating is the power source of contemporary architectural innovation, and make a argumentation through success and failure cases.
At the same time, architects modified the roofs and material colors and other aspects of the single building according to the same reference, they created a new architectural image.
Concerning colors and materials in the construction, it basically followed the traditional form of gray tiles and white walls, interspersed with the dark red reminding people that this architecture complex have historic content.
Only in this way, can architectural symbolic language be constantly recycled and continued, can traditional Chinese cultural symbols have correct expression in contemporary architectural design Acknowledgements This work was financially supported by Humanities and Social Science Research Project of Ministry of Education(13YJA790038)and Humanities and Social Science Research Project of Ministry of Education(13YJAZH087) References [1] Guan Ruiming, Nie Lansheng.
