Influence of Rare Earth Materials on pH Value and Oxidation Reduction Potential (ORP) of Drinking Water Lirong Huang* and Yuhang Chen School of Mechanical and Electrical Engineering, Jiangxi University of Science and Technology, Ganzhou Jiangxi, China huanglirong@sina.com* Keywords: iIon materials, drinking water, pH Value, ORP Abstract.
Experimental 2.1 Material preparation Preparation of rare-earth materials: rare-earth materials were mainly composed of rare-earth waste-residue powders, and other materials such as tourmaline, zeolite, cordierite, and kaolin.
Then the slop was put into the die specially designed for the rare-earth materials.

Numerical simulation of fracture propagation of heterogeneous material Zeqi Zhu1,2, a, Qian Sheng2,b and Xiaodong Fu2,c 1 Key Laboratory of Hydro-Science and Engineering, Chongqing Jiaotong University, Chongqing 400074, China 2 State Key Laboratory of Geomechanics and Geotechnical Engineering, Institute of Rock and Soil Mechanics, Chinese Academy of Sciences, Wuhan, Hubei 430071, China azhuzeqi2005@tom.com, bQsheng@whrsm.ac.cn, c fxd_scu@163.com Keywords: digital image processing; heterogeneous material; fuzzy clustering; fracture process; numerical simulation Abstract.
Therefore, the images, as a kind of information resource, are able to reflect meso structures perfectly base on different gray scales and colors, and are used to study the interior structures and defects of materials during the DIP.
While the image attributes for different interior materials are not quite distinguished, the method of fuzzy cluster analysis was introduced into digital image processing in this paper.
Then, the softening model is applied in software FLAC3D to simulate the rock failure of brittle material such as granite in this paper, and the mechanical parameters for different materials in Three Gorges granite are seen in Reference[3].

The use of natural materials for constructions, such as wood, makes it possible to respond to sustainability issues.
Introduction Wood is one of the oldest building materials that have been used by man and still plays a leading role in the construction world.
Many studies are moving in this direction, also in order to lenghten the life cycle of the materials used in the construction processes [4].
