Abstract: One of the valuable problems of modern science and technology is to create a low-power (less than 1 mW), long-life (10-100 years) miniature sources of electric power based on the conversion of radioactive isotopes of energy into electricity.
Physical processes in semiconductor materials especially in silicon under the influence of electrons are known and well understood, it is possible to form the specific technical requirements for the design betavoltaic batteries with maximum efficiency of conversion of radiation energy at their minimum size.

So the fire caused by woody decoration materials would be more and more.
Materials and methods Prepare of the castor stalk powder Castor stalk is from Zibo city, Shandong province, China.
Because the first phase is the dry stage and the pyrogenation of the wood materials is begin from the second phase, so it only studied the relationships between the pyrogenation (the pyrogenation of wood materials in the second and third phase) and the chemical composite amount.

It would lead to accurate predictions introducing microstructural features of materials [1-2].
Since this approach has been developed for monophasic metallic materials, it is now extended to biphasic materials in order to be applied to DSS.

Because of the weak side existing, and the model materials for low-tensile, the material tensile strength is even worse in the weak surface.

Comparison between the numerical and experimental results shows excellent agreement for various blank dimensions and materials.
The predicted critical BHF agrees well with the experimental results at various blank radii and for different materials.
Three sheet materials have been investigated to obtain the critical BHF that is the minimum BHF to prevent wrinkling.

Lab Simulation Study on Anti-cracking Performance of Asphalt Concrete Overlays for Fatigue Zuzhong LI1,a, Shuanfa CHEN1, Weidong LIAO2 and Ruixing YUAN1 1School of Materials Science and Engineering, Chang’an University, Xi’an 710061, Shaanxi，China 2Hanshi Highway Administration of Hubei Province, Wuhan 430051, Hubei, China azuzhongli@126.com Keywords: Asphalt overlays; Reflective crack; Stress absorbing layers; Simulation test Abstract.
The reflective crack simulation tests of bending and shearing styles with six asphalt overlays were carried out in order to evaluate the anti-cracking effects of different kinds of anti-cracking materials.
(2) By adding or setting the geotextile materials in the structure of asphalt overlays, the reflective cracking of the overlays is obstructed.
