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.

Introduction Inorganic and organic materials belong to two extensive categories according to the conventional classification of materials.
But when the inorganic molecules were combined with organic molecules/polymers using an appropriate method, the resultant hybrid materials can offer the combined merits of both classes of materials, thereby achieving combinations of properties that are not possible with either one of the two conventional materials.
This rapidly growing field is developing many exciting new materials with novel properties.
The properties of the hybrid nano-composite materials depend not only on the properties of their individual parents but also on their morphology and interfacial characteristics.
