会议发言英文 Thank you, prof. …. My name is ….. I’m from ….. I am very pleased to be here to join this forum. The topic of my presentation is properties of rapid construction materials for soil pavement of field airfield. As is shown in the picture, the main parts of my research are about soil pavement. My presentation will include these four parts: First, some background information about this research; second, the main work we have done; third, some conclusions we have got and the last: innovation and presentation of our published papers. Why I choose this item? I think it can be illustrated from the following four parts. First, the existing quantity of airfields is still not sufficient and the airfields have many shortcomings especially in war time. Second, the complementary facilities, such as highway runways are far less than airfields, however, have more weakness. Third, a certain amount of field airfield is quite necessary considering some emergencies such as rescue and disaster relief. Forth, the field airfield can fill the void of airfield and they can be combined to be airfield network. The meaning and aim of this research contains three parts. Fast, convenient and validity, fast means the field airfield must be constructed as fast as possible, convenient means the construction should need the minimum equipment, labor and materials considering the actual construction condition, validity means the constructed airfield is able to support the operation of given aircraft in specifically time. Just like many other territories, the situation of the research is that the U.S. Army takes advanced line. The U.S. Army declares that they can reach to anywhere on the earth in 96 hours, the most important method for force projection is though aircraft, thus rapid construction of pavement is the key problem for rapid force transportation. The main work we have done can be summarized as four parts, materials choosing, scheme making, mechanical properties research a
