Building materials is the most prominent representative in all human labor tools.

Products of building materials and equipment expressed with code has become a necessary today, even required by law.
Obviously, a sign of human’s free attributes lead to the development of building materials is the specialization, standardization and universality of building materials.

The Acoustic Emission Diagnose and Analysis of Journal Bearing‘s Inner Ring Looseness Fault by Truck Wheel Cai,Haichao1,a; Wang,Dongfeng2,b;Xu,Qiaoyu1,c;Shang,Zhendong1,d 1 School of Electromechanical Engineering,Henan University of Science and Technology,Luoyang,Henan,471003,china 2 Science and Technology Department , Bearing Institute of LuoYang , LuoYang, HeNan ,471003,china achclovely99@163.com,bwangdongfeng2006@163.com,cxiaoyu0622@163.com dcnlyszd@163.com Keywords: Rolling bearing; Fault diagnose; Looseness; Wavelet packet analysis Abstract: In this paper, we combine the characteristics of acoustic emission detection with the present condition of truck rolling bearing’s fault detection ,adopting the acoustic emission technique to examine railway freight car ’s journal bearing inner ring looseness .We put forward the method which wavelet packet analyze and withdraw bearing acoustic emission signal’s feature vector.
Acoustic emission technique is a dynamic detection method, which can get materials’ important information,fatigue crack propagation,under the dynamic loading conditions.
The bearing inner ring’s looseness is not bearings’ internal defects, but has the relation to the metal wearing between bearing inner ring and bearing journal[1]. in this paper, we adopt the acoustic emission technology to make a preliminary research and analysis of the bearing inner ring’s loose defect.
In the process of wearing, through the materials ’structure and phase change, the acoustic emission cooperates with superficial impact’s micro-process, rub belt’s damage, the expanding micro-cracks and wear debris’s transfer in the superficial layer.

Static corrosion behavior of refractory lining materials for magnesium electrolytic cell Shidong Wang1, 2, a, Quan Li1, b and Zhijian Wu1, c* 1Qinghai Institute of Salt Lakes, Chinese Academy of Sciences, Xining 810008, China 2The Graduate University of Chinese Academy of Sciences, Beijing 100049, China awshidong1006@163.com, bliquan@isl.ac.cn, c*zjw6512@hotmail.com Keywords: magnesium electrolysis; lining material; corrosion Abstract.
Fig. 5 SEM images of the specimens Conclusions The weight gain of the refractory materials after immersion in the electrolyte was due to electrolyte penetration into the micropores of the refractory materials.
Considering the comprehensive properties of the refractory materials, porous clay brick was found to be the best lining material for magnesium electrolytic cell among all the tested refractory materials.
