The materials of the earth construction, namely the earth, is the ideal building materials that can keep the balance of the ecological system.
Figure3, 4, 5, 6, 7 indicates that due to the better thermal stability of the adobe house's materials, namely the earth, the tested date of each parts, though there are some differences, remain the same trend of curve. the thermal bridge part of the door, window and etc. have little effect on the wall.
People around the local environment can find local building materials to build house since ancient times.
Soil and wood are two of the most eco-nature materials approved by today's ecological principles; compared with other building materials, they both have the strongest biodegradable and recyclable and the least energy consumption and pollution emissions.

The higher resistance against deformation that these materials possess provides the desired stability of the auto body in crash situations but also leads to higher mechanical and tribological loads on the forming tools during the production process [1].
Tool Selection It was necessary to use superabrasive cutting materials (diamond or cBN) because of the high amount of tungsten carbide in this coating.
The high grain protrusion and the very low amount of bonding material (except of the identical nickel-plating) permitted the comparison of diamond and cBN grain as cutting materials, with a minimum influence of the bonding system.
The index xx% stands for the boundary material fraction value.

Applications of Elastico-mechanoluminescent Smart Materials 8.
The ML intensity of thermoluminescent materials increases with the irradiation dosage given to the materials.
Thus, the EML materials have potential to sense the stress.
Using the coating of mechanoluminescent materials the non-destructive testing of materials can be performed [1, 2]. 8.
