Keywords: Insulation brick; quartz sand; porous structure; control technology.
Quartz sand has unique physical and chemical properties, especially its internal molecular chain structure, crystal shape and lattice changes, so that it has a high temperature, thermal expansion coefficient is small, highly insulated, corrosion resistance, piezoelectric effect, resonance Effect and its unique optical properties, in many high-tech products play an increasingly important role [6-8].
From Fig.6, when the water content ratio is 0.85, the structure of the finished product in SEM is 0.9 and 1, the structure with the smallest porosity is more uniform and denser.

Abstract.
The structures of bare Co-Ni mixed oxides and Co-Ni mixed oxides/graphene composite is clearly studied by X-ray diffraction.
As one of novel carbon materials, the graphene possess the unique two dimension plate-like structure, and the single-layer carbon texture endows with excellent electric, thermodynamics, mechanic properties, as well we ultra-high specific surface area [9, 10].

The author emphasize on the discussion of water chemistry and D/18O, combined with the characteristics of geological structure, analyze the recharge sources and flow path,recharge elevation and recharge area, division of underground water system of the geothermal water in Guihu district.
Guihu geothermal resource sits on north of Fuzhou-Yongtai structure.
The fault always forms negative terrain in landscape, which has an apparent characteristic of tension, and become the main structure to control and conduct heat in study area.
Figure 1 Sketch of geological structures in Guihu.
Each sample is divided into four parts for different goals, which consists of chemistry analysis of groundwater, trace element analysis, hydrogen and oxygen isotope analysis, strontium isotope analysis as well.

The characteristics of the course are to explore the best analysis methods on the basis of the typical chemical structure, physical and chemical properties, and the existing conditions in order to control the drug quality.
Students are required to possess knowledge of organic and analytical chemistry, medicinal chemistry, pharmaceutics, etc.
In general education program, pharmaceutical analysis was simultaneously established with medicinal chemistry preceding pharmaceutics before, so it is difficult to learn well for student.
Emphasizing the integrity and comprehensiveness of knowledge In each section, the studying will be based on the chemical structure and physic-chemical properties of typical drugs.
Multimedia courseware for classroom teaching combines the traditional oral interpretation and blackboard writing, and dynamic slides make the original boring chemical structure and analytic reaction process embodied in the vivid animation way.

Still 1920, Albee and Morrison [2] have found that the rate of bone regeneration increases when β-TCP injected into the gap produced by the appearance of a defect in the bone structure. β-TCP is available in granular or block form, with compact or porous structure; β-TCP with porous structure shows compressive strength and elongation like sponge bone [3], but it is fragile and has a low resistance to shear stress [4].
TCP/CH /polymethylmethacrylate cement were prepared by interpenetrating bulk polymerization of methyl methacrylate (MMA) monomer in structures of TCP-CH.
Several factors of the material, such as surface hydrophobicity [18], surface charge [19], surface roughness [22] and surface chemistry [20-21], have been shown to influence cement formation.
To investigate the role of TCP/CH in mixing with PMMA causes the significant changes of structure cements.

Two pieces of PMMA slides were put respectively on and under the PC glass slide to form “sandwich” structure.
The 3D highly ordered face-centered cubic (fcc) structures can be clearly seen in both PC and MIPC films.
The inverted opal structures of MIPC have advantages on sufficient surface areas, tough mechanical strength, better sensitivity and optical property in sensing the target analytes[12,13].
Upon the analytes adsorption, the porous structure of MIPC will swell, inducing the red shifts of Bragg diffraction.

Fig.1 is the scheme of microwave absorbing structure [18].
The multilayer structure absorbing materials of the fiber and epoxy resin composites have good microwave absorption properties.
This difference could be caused by the different size and structure of the CNT.
The last is intelligent, the so-called smart materials refers to the perception function, information processing function, self-instruction, and the signal to make the best response function of materials and structures.
