1、英文学术报告演讲稿国际会议作报告英语发言稿 Thank you, prof. 。. My name is 。. Im 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

2、 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 illus

3、trated from the following four parts. First, the existing quantity of airfields is still not sufficient and the airfields have many ings especially in war time. Second, the plementary facilities, such as highway runways are far less than airfields, however, have more weakness. Third, a certain amoun

4、t 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 bined to be airfield network. The meaning and aim of this research contains three parts. Fast, convenient and validity, fast

5、 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 spe

6、cifically 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 pa

7、vement 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 and water-stable properties research. We choose two kinds of soils, which are got from Xian, Shanxi province and Jiu

8、quan, Gansu province separately. The sand from Ba River was considerate to investigate the influence of sand to the properties of stabilized soil. The chosen three kinds of powders are cement, lime and new-type stabilizer developed by Changan University. The principles in considering the function of

9、 4 kings of fibers are referring different length, type and mixing them. On account of the time, I will make a brief description about the experiment scheme. In summary, three parts were proposed to distinguish the affecting factors in making experiment scheme. They are powder control, fiber control

10、 and other factors. Taking powder control for example, the dosage of cement is respectively 6%, 8% and 10% when the soil is stabilized only by cement, while the dosage of cement decrease to 3%, 5% and 7% when the lime is addicted to stabilized soil. The following two factors are stabilizer and sand.

11、 Six kinds of experiments were performed to investigate the influence of above factors to the mechanical properties of stabilized soil. The aim of paction test is to find the maximum dry density and optimum moisture content. The aim of pression strength test is to determine the optimum dosage of cem

12、ent, lime, powder stabilizer and fiber, meanwhile evaluating the performance of stabilized soil. The aim of splitting tension strength test is similar to pression strength test, the left picture is sample stabilized by cement, while the right picture is the sample stabilized by fiber and cement. The

13、 direct sheer is another important parameter in geotechnical engineering. It influences the foundation bearing capacity and many other properties especially for soil base and base course. The left picture shows the course of making sample and the right picture shows the test process. The CBR test an

14、d rebound modulus test are referenced from highway test specification to evaluating the prehensive capacities of each structure level of the pavement. For both the two tests, the left picture shows the course of making sample and the right picture shows the test process. What should be noted is that

15、 the number of sample is at least 6, the last result is the average value of these date got from test after eliminating the bad results. Four kinds of experiments were performed to investigate the influence of above factors to the water-stable properties of stabilized soil. The scouring test is not

16、the stated experiment in current specification. It is performed by us through looking up large quantity of interrelated literature, and two different ways to carry out. The left picture shows the method of vibration table and the right picture shows the method of fatigue test instrument. Penetrant t

17、est refers to the experiment in relating concrete specification. The left picture shows the process of saturation, the right picture shows the test process. Cantabria test and other tests are all original experiments; they are used in stabilized soil for first time, here I will not develop my narrat

18、ive. As regards the innovation, I think it throughout the whole research, including materials choosing, scheme making, mechanical and water-stable experiments. I think it can be drawled from the following keywords, such as soil choosing, sand, powders, fibers, and so on. Three main parts can be summ

19、arized. First, selecting two kinds of soils, three kinds of powders, several binations; second, several kinds of fibers, different length and admixture; third, prehensive experiments, test method and test instrument. 英文学术报告演讲稿 In my 18 years of life, there have been many things. University days are

20、the best part of them. I can never forget the days when I stepped into my university. I was impressed by its garden-like campus, its enthusiastic students and especially its learning atmosphere. I at once fell in love with it. After the arduous military training, I get absolutely absorbed in my stud

21、ies. The classes given by the teachers are excellent. They provide us with information not only from our textbooks but from many other sources as well. They easily arouse my insatiable desire to take in as much as I can. Frankly speaking, at first I had some difficulty following the teachers. Howeve

22、r, through my own efforts and thanks to my teachers guidance, I made remarkable progress. Now Ive benefited a lot from lectures and many other academic reports. Learning is a long process; Ill keep exploring in the treasure house of knowledge to eich myself. This summer I got out of the ivory tower

23、and entered the real world. A publishing house offered me a part-time job in pilation and revision. At the beginning I was belittled by my colleagues. But they were really surprised when I translated seven English articles over 5,000 words on only one day. Gradually, they began to look at me with re

24、spectful eyes. In their opinion I turned out to be a useful and trustworthy colleague. I also realize that only those who bring happiness for others can be truly happy. So I often take part in activities concerning public welfare. I once went to a barren mountain village with my classmates. We taugh

25、t the kids there who could not afford school. While showing them how broad and how civilized the outer world is, I was deeply touched by their eagerness to learn, their honesty and their purity. I couldnt control my tears on the day when we left. The precious experience with the poor kids made me aw

26、are of the responsibility on the shoulders of us, future teachers. Besides study and social practice, there are entertainments as well. I do body building every day, hoping to keep healthy and energetic. We also write a play and put it on in our spare time. Campus life is the most splendid time. But

27、 different people have different choices. The majority of students cherish their beautiful season and cherish the hope that one day theyll e outstanding. But there are indeed some students still under ignorance. They gather together for eating, drinking or playing cards. Theyre busy in searching for

28、 a girlfriend or a boyfriend. They forget pletely about their mission as college students and the hope of their motherland. Finally, I do hope everybody can try their best to e a worthy citizen of the country. I do hope everybody can e the backbone of our nation and make great contributions to socie

29、ty! 英文学术报告演讲稿 Good morning everyone. e to my presentation. My name is 。My major is mechanical engineering. The research direction of my team is the robot, so Ill talk something about applications of the teleoperator robot in our life with two examples. The main contents of my speech are the medical

30、robot and the cooking robot. First of all, we should know what teleoperator robot is. Teleoperator robots are mainly used for various operations of non-industrial production, for example, the medical robot, the cooking robot and the cleaning robot. Lets first see the medical robot. The main characte

31、ristics of the medical robot is remote control. The remote control lets people stride across the space-time barrier. It means that the doctor and the patient can be in different places, as is shown in the pictures. The patient is in Strasbourg while the surgeon is in New York. The display screen pro

32、vides surgery scene to the surgeon. By operating the main operation terminal and inputting mands, doctors can control the robot to have surgery. Robots can also serve our daily life. Most of us may already know that the robot cooks in the university cafeteria of Beijing Jiaotong University. We all think that its very interesting. These pictures show us the process of the robot cooking. First, the chef puts raw materials into the robot, then choses the dish to cook in the display screen. Next, the robot starts to cook. In the cooking process, the c
