The rockfill dam has strict requirements on rockfill materials, not only reduce the super-size materials and control the fine aggregates, but also have a good gradation [1].
Because Eq.3 assumed that blasting rockfill gradation fully complied with Talbot distribution, then rockfill materials were strictly self-similar.
Primary rockfill materials adopted till conglomerate.

When compared with other sol-gel materials, xerogels represent a class of nanocomposites that are relatively easy to fabricate but with unique thermal, acoustic, optical and mechanical properties for rapid sensor or device prototyping development [3-4].
Ethanol-based Rhodamine B solution is also used extensively as a fluorescent dye to enhance the deposit of superglue-developed fingerprints in forensic science.
However, the potential applications of Rhodamine B doped nanocomposites in forensic science, latent fingerprint detection in particular, were still unclear [5-7].

The quality of the collector material and absorption of light have a close relationship.
Commonly, solar selective absorber used as absorption material of collector [3-5], it has good sun radiation absorption, and only a small amount of infrared heat radiation.

So, people behind sandwich plate are fastened. 1 Introduction Currently, conventional weapons, battlefield protection bunkers killing means Airlines shells Earth Penetrator, drill Bomb them by destroying fortifications to achieve the purpose of killing the internal staff, but with the development of science and technology on the battlefield strong shock wave produced by the explosion has become one of the important means of anti-personnel, even if it is a weak shock wave can also be caused by the protective bunker internal staff great harm.
Therefore, in order for the effective protection shockwave damage, the paper proposes a new material the foam aluminum - steel layer plywood, laminated board composed of two materials: the upper and lower levels of steel and aluminum foam core material.
The model shown in Figure 1, using one of the two models, cm-gs modeling, is composed of four materials of explosives, air, steel and aluminum foam.
