Introduction Since 1948 USA scholar Rabinow invented the magneto rheological fluid, because of its rheological properties stable: under the external magnetic field can be instantly (milliseconds) into a Bingham fluid with high viscosity fluid shift from the Newton with good liquidity and low viscosity, and seem as if solid with mechanical properties, remove the external magnetic field will back to Newton fluid, having the characteristics of continuous, reversible, controllable and high response rate[1-3], which makes the application research of magneto rheological fluid has been extended to civil engineering, mechanical engineering, vehicle engineering, equipment manufacturing and other fields[4-6].

The Establishment of EPC General Contractor Risk Evaluation Model Based on Extension Matter-Element Theory Weike Chen1,a, Qingwei Ge1,b Peng Yu1,c 1Department of Management , Tianjin University of Technology, Tianjin300384, China a chenweike7@163.com,b geqingwei11@163.com,c 712688110@qq.com Key words: EPC contracting; Extension Element Model; Risk evaluation Abstract: Due to the wide scope, many participants and long construction time of project, the risk of EPC general contracting is far greater than the common engineering contracting.
It is a nature that the EPC project is quite complicated because of involving organizations and institutions in different countries and covering knowledge in multi-disciplinary, such as civil engineering, chemical industry, hydraulic power, electric power, management science, and economics.
It is a cross discipline which is associated with philosophy, mathematics and engineering[6].
Yan Hongyan etc. manage to get objective and accurate outcome when they apply the extension evaluation method for the success degree of international engineering general contracting project[8].This article introduces the extension matter-element model to evaluate risk of EPC project, and the details are as follows.
