Good morning everyone. Welcome to my presentation. My name is …My major is mechanical engineering. The research direction of my team is the robot, so I’ll talk something about applications of the teleoperator robot in our life with two examples. The main contents of my speech are the medical 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. Let’s first see the medical robot. The main characteristics 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

provides surgery scene to the surgeon. By operating the main operation terminal and inputting commands,

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 it’s 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 chef follows the robot’s voice prompts to add spices. Just three minutes later, the robot pours the cooked dish into the prepared basin. The robot cooking not only takes less time but also uses less gas. It can save fifty percent of gas.

As the above examples allude, teleoperator robots provide service for mankind and make our life more convenient. Meanwhile they save us a lot of time and sources of energy. I believe in the future teleoperator robots will be more widely used and provide better service to our life. That’s all. Thank you.


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 Army takes advanced line. The 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 and water-stable properties research.

We choose two kinds of soils, which are got from Xi’an, Shanxi province and Jiuquan, 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 Chang’an University. The principles in considering the function of 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 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.

Six kinds of experiments were performed to investigate the influence of above factors to the mechanical properties of stabilized soil. The aim of compaction test is to find the maximum dry density and optimum moisture content. The aim of compression strength test is to determine the optimum dosage of cement, lime, powder stabilizer and fiber, meanwhile

evaluating the performance of stabilized soil. The aim of splitting tension strength test is similar to compression strength test, the left picture is sample stabilized by cement, while the right picture is the sample stabilized by fiber and cement. The 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 and rebound modulus test are referenced from highway test specification to evaluating the comprehensive 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 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 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 test 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 narrative.

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 summarized. First, selecting two kinds of soils, three kinds of powders, several combinations; second, several kinds of fibers, different length and admixture; third, comprehensive

experiments, test method and test instrument.

篇三:英语演讲稿 Word 文档



In my 18 years of life, there have been many things. University days are 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 studies. 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. However, through my own efforts and thanks to my teachers' guidance, I made remarkable progress. Now I've benefited a lot from lectures and many other academic reports.

Learning is a long process; I'll keep exploring in

the treasure house of knowledge to eich myself. This summer I got out of the ivory tower and entered the real world. A publishing house offered me a part-time job in compilation 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 respectful 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 taught 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 couldn't control my tears on the day when we left. The precious experience with the poor kids made me aware 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

Campus life is the most splendid time. But different people have different choices. The majority of students cherish their beautiful season and cherish the hope that one day they'll become outstanding. But there are indeed some students still under ignorance. They gather together for eating, drinking or playing cards. They're busy in searching for a girlfriend or a boyfriend. They forget completely about their mission as

college students and the hope of their motherland.

Finally, I do hope everybody can try their best to become a worthy citizen of the country. I do hope everybody can become the backbone of our nation and make great contributions to society!













英语演讲稿-My definition of success Source: XX-04-16 我要投稿恒星英语学习论坛Favorite

英语演讲稿-My definition of successToday I am very glad to be here to share with you my ideas of success. What is success It is what everyone is longing success would be rather simple. Winning a game is success; getting a high grade in the exam is success;

making a new friend is success; even now I am standing here giving my speech is somehow also success.

However, as a person’s whole life is concerned, success becomes very complicated. Is fortune success Is fame success Is high social status success No, I don’t think so. I believe success is the realization of people’

s hopes and , in the modern society there are many people who are regarded as the successful. And the most obvious characteristics of hem are money, high position and luxurious life. So most people believe that s success and all that they do is for this purpose. But the problem is wether it is real success. We all know there are always more money, higher position and better condition in front of us. If we keep chasing them, where is the end What will satisfy us at last Therefore, we can see, to get the real Success we must need something inside, which is the realization of people’ hopes and ideals.

Different people have different ideas about success; cause people’s hopes and ideas vary from one

another. But I am sure every success is dear to everybody, cause it is not easy to come by, cause in the process of our striving for success, we got both our body and soul tempted, meanwhile we are enlightened by the most valuable qualities of human beings: love, patient, courage and sense of responsibility. These are the best treasures. So now I am very proud that I have this opportunity to stand here speaking to all of you. It is my success, cause I raise up to challenge my hope.

What is success Everyone has his own interpretation as I do. But I am sure

every success leads to an ever-brighter future. So ladies and gentlemen, believe in our hopes, believe in ourselves, we, every one of us, can make a

successful life!

Wish you all good success!



Thirty college students across the country attended the Tenth 21st Century Cup National English Speaking Contest in Beijing on April 10. Eventually, Xia Peng, from Nanjing University was named the

champion. The second and third places went to Zhang Jing, a sophomore from China Foreign Affairs University, and Zhang A Xu, from Hong Kong Polytechnic University, respectively. More than 1000 college students in Beijing are lucky birds to listen to the speeches on the spot in Friendship Hotel.

Just make to it the finals, they had to get past 60 others speaking on “The impact of globalization on traditional Chinese values”. That was at the semi-final on April 8-9. What will Chinese college students think about the impact Each contestant had his own take on the subject. Xia summed up globalization by saying: “It’s just controversial and hard to say whether it is good or bad.” Xia took the old wall of his city, Nanjing, as a metaphor. He spoke about the conflict over whether to protect the old walls or tear them down to represent the conflict of ideas. He suggested that people protect the wall as a valuable relic while tearing down the “intangible walls”of their minds that prevent communication. While some other students are more focusing on the impact of globalization on family relations, attitudes towards love, and job-hunting.

Over the past 10 years, the national English speaking competition has given contestants a chance to speak on a variety of topics closely related to their lives. Chinese students become more open-minded and receive various ideas and thinking over the decade. Diversity becomes more obvious on campus, students have more opportunities to express and show themselves. It’s not an easy task for the contestants to win through the fierce competition. Owning to their passion, hard work and persistence, they finally succeeded in the contest.

Liu Xin, the first champion of the national contest, is now an anchorperson of CCTV-9. Recalling the passion of study on campus, she said: “When you want to express your idea by a foreign language without finding a right way, you’re really upset. Then you have to encourage yourself, and after a long term of bitterness, suddenly you find you get the right way with joy.” With the champion title in 21st Century Cup, Liu attended the International Public Speaking competition in London in May 1996 afterward and got the first prize historically.

The winner in XX surprised the audience, since she

came from accounting major instead of English major. Gu Qiubei, then 22 years old, was a senior in Shanghai Foreign Studies University. While being asked whether she had some good methods to learn English, she said: “Learn English with passion and enthusiasm.”Attracted by the greatness of English language, Gu even changed her major from accounting to English in her postgraduate study. The most important issue in English learning process she pointed out is personal interests. Only people interested in English benefit a lot from the learning methods and those with passion will finally achieve their dreams.

When chief of global media giant Viacom Sumner Redstone gave a speech in Tsinghua University on his autobiography A Passion to Win, he was asked what made him to restart his career at the age of 60, the 81-year-old media tycoon said: “Firstly, there’s a self-driving force in my deep heart, which keeps my passion to succeed and surpass others; secondly, I don’t think I’m too old to leave work, actually I love my work very much.” Some of the contestants have achieved their dreams as Redstone; still others are on the way

to their dream. With a passion to win, you will overcome obstacles and succeed at the end.

I’m studying in a city that’s famous for its walls. People who visit my city are amazed at the imposing sight of its walls, especially when silhouetted against the setting sun with gold, shining streaks. The old, cracked bricks are covered with lichens and the walls are weather-beaten guards standing still for centuries.

Our ancestors liked to build walls. They built walls in Beijing, Xi’an, Nanjing and many other cities, and they built the Great Wall, which snakes across half our country. They built walls to protect against enemies and evil spirits. This tradition has survived to this day: we still have many parks and schools walled off from the public.

For a long time, walls were one of the most natural things in the world to me.

My perceptions, however, changed after I made a hiking trip to the eastern suburbs of my city. My classmates and I were walking with some foreign students. As we walked out of the city, we found ourselves flanked by tall trees, which formed a wide

canopy above our heads. Suddenly one foreign student asked me, “Where is the entrance to the eastern suburbs”“We’re already in the eastern suburbs,” I replied. He seemed taken aback, “I thought you Chinese had walls for everything.” His remark set off a heated debate. At one point, he likened our walled cities to “jails”, while I insisted that the eastern suburbs were one of the many places in China that had no walls.

That debate had no winners, but I did learn a lot from this student. For instance, he told me that some major universities like Oxford and

Cambridge were not surrounded by walls. I have to admit that we do have many walls in China, and as we develop our country, we must look carefully
