The Study on Building Materials’ Optimization Based on Fuzzy Technology Liwen You Vocational and Technical College, University of Science and Technology Liaoning youliwen23423@163.com Keywords: Fuzzy technology; optimization; building materials Abstract.
Finally, a building materials optimization scheme is put forward a kind of fast, reliable program completion, it is never seen evaluation building materials.
It’s scarcely used in optimization of building materials, so we added a process as the lower part in the Fig.1.
Through investigation and analysis, data collection, combined with qualitative analysis in the effect of building materials for building a village, a new village economic evaluation of building materials is established, which contains 3 levels and 14 representativeness indexes (Fig.2).
Conclusion Three indexes with 14 sub-indexes have been used for assessing three different building materials.

Electrode Material The earliest electrodes material in super capacitor is carbon materials.

In the paper, the continuous conceptual problems of discontinuous materials are discussed and finite element method mesh generation based on material-discontinuous-nature is researched.
When the research range is tend to the size of the materials particle or crystal grain, the assumption of continuum theory need to rediscuss.
The soils is composed with clay particles and binding materials.

Professional paper shows the general characteristics of graded materials, their previous industrial use and potential use of graded materials in the future.
Introduction Graded materials (FGM - Functionally Graded Materials) are in intensive use for last two decades.
The largest groups of graded materials are as follows: - bioactive graded materials, - tool steel with C, V, Cr and Ti gradients, - materials with self-lubricating ability, - graded materials with high temperature resistant surface layer. 2.
Properties of functionally graded materials Graded materials are very innovative product in the field of technology.

Numerical Investigations of Ultrasonic Scattering from voids in Composite Materials Based on Random Void Model1 Li Lin, Xiang Zhang, Jun Chen, Ximeng Li NDT & E Laboratory, School of Materials Science & Engineering, Dalian University of Technology, Dalian, Liaoning Province, China linli@dlut.edu.cn Keywords: Composite; Porosity; Ultrasonic attenuation; Random void model; Morphology.
Even at the fixed porosity, ultrasonic attenuation coefficient fluctuates due to the randomness of void morphology in CFRP composite materials.

The Properties of Modified Adobe Materials with Desulfurization Waste* Xingwen Jia Yajie Zhang Jueshi Qian (College of Material Science& Engineering, Chongqing University, Chongqing, China) (E-mail:jiaxingwen@126.com) * Key Technologies R&D Program of China(Project Number: 2006BAJ04A04-02) Keywords: desulfurization hemihydrates gypsum (DHG); desulphurization fly ash (DFA); modified adobe materials; drying shrinkage; durability Abstract: As a modifier, desulfurization waste can improve the performance of traditional adobe materials.
Currently, the modifiers of adobe materials are cement, lime，fly ash and other cementations materials [3,4].
Consequently, adding DFA into the adobe materials, the water resistance of adobe materials can be improved significantly.
