Using constitutive equations of piezoelectric materials and an equation of the plate’s motion a matrix of characteristics of the system was obtained.
Research in this area concern the reliability of machines, increasing the speed and range of displacement and applications of new materials.
Piezoelectric materials can be described by a pair of constitutive equations that describe relations between electrical and mechanical properties.
Especially nowadays, when a significant increase of applications of smart materials is observed in modern technical devices.

But and of the nanoporous materials are unknown.
In order to obtain and, the FEM for the solid materials of nanoporous materials are made (shown in Fig. 3 and Fig. 4).
The size of the two models is the same to the one of the nanoporous materials.
In the solid FEM, the materials properties for the solid materials and the Si substrate are given out in Table 2.

Theoretical Calculation for Far Infrared Emissivity of Tourmaline Powder Materials Peipeng Wanga, Jinsheng Liangb, Junping Mengc, Yan Dingd and Yilin Hane Institute of Power Source & Ecomaterials Science, Hebei University of Technology, Tianjin, 300130, China asg.come@yahoo.com.cn, bliang_jinsheng@sina.com, cmengjunping@hebut.edu.cn, ddingyan@hebut.edu.cn, ehanyilin1983@126.com Keywords: tourmaline, mineral materials, infrared emissivity, theoretical calculation, model朗读 Abstract.
For the single powder materials, the main factors that affect the infrared emissivity of materials are crystal structure, chemical composition, ability of thermal excitation, and powder particle size (shown in Fig. 3).

Impact of pH Value and Temperature on Cement-based Materials Adsorbing Heavy Metal Ions Yali Wanga*, Suping Cuib, Xikui Xuc, Mingzhang Land College of Materials Science and Engineering, Beijing University of Technology, 100 Pingleyuan, Chaoyang District, Beijing 100124, China.
Micro-structure analysis shows that cement-based materials’ main adsorption methods are different when pH values are different.
Permeable pavement materials can discharge the rainwater very fast and prevent surface accumulated water.
Summary Cement-based materials have selective adsorption phenomenon for different heavy metal ions (Cu2+, Zn2+, Pb2+, Cd2+).In addition to zinc ions, the cement-based materials’ capacity of adsorbing heavy metal ions increases as the pH value and the temperature increase.
