At the same time, we have to consider thermal conductivity, strength, material cycle and safety of insulation materials synthetically.
Besides, these insulation materials all required the best price and good processing technology, etc.
Currently there were many common insulation materials used in rural wall, but these materials were not well in the rural area because of lots of reason，such as the price, the construction and the other .
For Flat roof design, many good materials were used to arrange between the waterproof layer and the sloping layer.

The results show that the degradation of materials might be one reason for the time-dependent O-ring leakages and can be used to prevent O-rings from field failures.
The FEM analysis relies on the constitutive equations of the materials to describe the materials’ mechanical properties.
Nevertheless, as an important failure mechanism, the degradation of materials should be carefully monitored to prevent the O-rings from potential damages.

Influence of Different Auxiliary Activators Doping on Spectral Properties of Sr3Al2O6: Eu2+ Phosphors Chao XUa, Dian-qing LU, Hai-feng JIANG School of Science, Huaihai Institute of Technology, Lianyungang, 222005 China axch09@126.com Keywords: Auxiliary activator; Strontium aluminate; Red long afterglow material Abstract: The long afterglow luminescent materials Sr3Al2O6: Eu2+, Re3+ ( Re= La, Ce, Pr, Nd, Sm, Gd, Dy, Er) were synthesized via solid-state reaction.
The materials were weighted according to the composition of (Sr2.8Eu0.1Re0.1)(Al1.8B0.2)O6 ( Re= La, Ce, Pr, Nd, Sm, Gd, Dy, Er).
The raw materials added with proper analytical alcohol were mixed thoroughly by a magnetic stirring for 2 h and then dried at 100 °C for 8 h.

Furthermore, ceramic materials containing natural cracks were also evaluated by this technique.
From the results, it was shown that this technique is valuable as a novel NDE technique applicable to ferro-magnetic and para-magnetic materials containing fatigue cracks and to ceramic materials containing natural cracks.
Since high frequency current, which is not influenced by magnetic permeability, is impressed on the specimen, ferromagnetic materials as well as paramagnetic materials can be inspected.
Results and discussion Detection of artificial defects for conductive materials.

With diamond particles, metal powders and a special soft material as raw materials, this paper introduced some diamond bits to drill the superhard materials such as granite.
Experimental Materials.(1) Metal powders By making appropriate adjustments of WC-based matrix component materials, different hardness of the matrix[3] will be achieved.
The adhesion of making pits material and matrix materials is weak, it is easy to fall off in the drilling process.
