英语两分钟演讲

Small Kindness

Small kindnesses are those simple deeds of goodness that we perform in our daily life, not merely to our friends and kin, but also to complete strangers, not for the sake of receiving some remuneration in return, but sheerly out of a spirit of generosity and unselfish consideration for the

welfare of others.

When we read the daily newspapers, we are frequently appraised of the Big Kindnesses performed by well-to-do philanthropists who donate large sums of money for the establishment of schools, libraries, free hospitals for the poor, orphanages, and the like. These, of course, are laudable acts of charity that deserve wide public acclaim. But in my estimation, those many minor acts of kindness performed daily ion assorted situations by public-minded citizens who receive no recognition or plaudits from the

mass media are equally commendable.

I think that in the eyes of the Almighty, the good-hearted white-collar worker who gives up his seat on a crowded commuter train to someone frail, aged or crippled, even though he himself is extremely tried after his day’s work, is just as deserving of praise, or maybe even more so, than

the billionaire philanthropist who has given away a million dollars for the establishment of a new old people’s home.

In the large cities of any country, where the general tendency of the people is “to look out only for one’s own interests”, the atmosphere is cold and miserable for those unable to keep up with the rapid pace of competition. Let us

all try remedy the situation by launching a personal campaign to perform a small kindness each day, no matter how inconsequential it may seem, so that our society will be

a much better place to live in.

平凡的善行

平凡的善行就是一些我们在日常生活当中所做的、简单的好事。不只对我们的亲友,结全然陌生的人也一样;不是为了报酬,完全是出自

一种为他人福祉的慷慨、无私的精神。

我们每天看报,常得知富有的慈善家所作“伟大的善行”。他们捐很多的钱盖学校、图书馆、免费为穷人看病的医院、孤儿院等等。当然这 值得民众赞美的慈善行为。但我认为,那些没受到大众传播媒介褒奖或赞扬、具有服务大众热忱的市民所作较小的善行,一样值得赞赏。 我认为在上帝眼中,一个好心的白领阶级,即使在工作一天后极度疲惫,在挤满通勤者的火车上让位给老弱或残障者,也一样值得赞美,甚至比那些捐一百万元建造一座新的老人院的亿万慈善家更值得表

扬。

在任何国家的大城市,居民的共同倾向就是“自扫门前雪”。对于那些无法赶上这种快速竞争步调的人,气氛是冷默无情的。让我们发起个人运动,试着来修正这促情形。无论事情多么微不足道,每天是行一

善,那么我们的社会将会更适于居住。

Recently, ther is a heated debate in our society. The college students are the bene ficiaries of a rare privilege, who receive exceptional education at extraordinary places. But will we be able to face the challenge and support ourselves against all odds? Will we b e able to better the lives of others? Will we be able to accept the responsibility of buildi ng the future of our country? The cynics say the college students are the pampered lost generation, which would cringe at the slightest discomfort. But the cynics are wrong. The college students I see a re eagerly learning about how to live independently. We help each other clean the dormit ory, go shopping and bargain together, and take part time jobs to supplement our pocket money. The cynics say we care for nothing other than grades; and we neglect the need fo r character cultivation. But again, the cynics are wrong. We care deeply for each other, w e cherish freedom, we treasure justice, and we seek truth. Last week, thousands of my fel low students had their blood type tested in order to make a contribution for the children who suffer from blood cancer. As college students, we are adolescents at the critical turning point in our lives. We all face a fundamental choice: cynicism or faith, each will profoundly impact our futu re, or even the future of our country. I believe in all my fellow classmates. Though we a re still inexperienced and even a little bit childish. I believe that we have the courage an d faith to meet any challenge and take on our responsibilities. We are preparing to assum e new responsibilities and tasks, and to use the education we have received to make our world a better place. I believe in our future. 我对未来充满信心 尊敬的评委,各位同学: 爱思英语学习网 爱思英语 - 中国最受欢迎的英语学习网站 - / 1 下午好! 最近,社会上有一场很激烈的争论.大学生是一种稀有特权的享有者,在很棒的地 方接受高等教育. 但是, 我们能面对挑战而无所畏惧吗?我们能够改善他人的生活吗?我们 能够承担建设祖国未来的重任吗? 怀疑论者说大学生是被宠坏的一代,一丁点挫折都受不了.但是他们错了,我所看 到的大学生正在努力的学习独立生活.我们互相帮助打扫卫生,一起上街砍价购物,一起参 加兼职工作来赚零花钱. 怀疑论者说我们除了成绩什么都不关心,从而忽略了性格的培养.但是,他们又错 了.我们彼此关心,我们向往自由,我们珍惜公正,我们追求真理.上个星期,很多我的同 学去验血,为了给患血癌的孩子贡献自己的力量. 作为大学生,我们是处在人生分水岭的青年.我们都面临一个重要的选择:怀疑人 生还是相信自己,每一种都会给我们的人生带来重大的影响,甚至影响我们祖国的未来.我 相信我们的同学们,虽然我们依然缺乏经验,甚至有些志气,但是我相信我们有勇气和自信 来面对生活的挑战并承担我们的责任. 我们正努力准备接受新的任务, 用我们所学习的知识 将世界变得更美好.我对我们的未来充满信心. 大学生英语演讲稿 17 Change The Ingredients Of Your Life 十七, 王晨,20 岁,安徽 Change The Ingredients Of Your Life This is a glass of water, tasteless, right? However if you add sugar, it will taste s weet, but if you add vinegar, it will become bitter. The same is true with our life____ th e flavor is created by our choices. If kindness is added to a strange you will have a friend; but if hostility is added, you will have an enemy. If love is added to a pile of red bricks you will have a home, but if hatred is add to those bricks , you will have an concentration camp. So my dear friends, never

complain that life is boring and the world is disappoint ing. If don't like the taste of your life, change the ingredients. Three year ago, I weighed more than 100 hundred kilograms which caused signifi cant embarrassment and frustration in my life. Like always failing my P.E examinations, li 爱思英语学习网 爱思英语 - 中国最受欢迎的英语学习网站 - / 2 ke always being laughed at by girls, like being terrified to speak in public. It was my gr andmother's encouragement that revived from my passive attitude to become confident in myself. She said " My dear, if you can't change you figure, why not treat it as your ow n style. So I began to cautiously employ the new way of thinking. By choosing to chang e my outlook on life, I developed the confidence to make a difference and finally I foun d a totally new world. So my dear friend, if faith, hope, love, endurance are added to your life, you will find the confidence to conquer your limitation and embrace new challenges. And hopefull y with my speech included, you will have a fantastic speech contest. 改变生活的味道 这是一杯白开水,平淡无味,对吧?可是加上点糖呢,他尝起来会有甜味;如果加 的是苏打水,味道就会变苦.人生同样如此——个中滋味在于我们的选择. 善待他人,你会拥有朋友;但如果充满恶意,则会多个敌人.将爱赋予一堆红砖, 你会拥有一个家;用仇恨来浇铸这堆红砖,就会铸成一座集中营. 因此亲爱的朋友们,不要抱怨人生乏味,世间无望.不喜欢生活的味道,那就换一 换生活的调料吧! 三年前,我重达 100 多公斤,这给我带来了很多尴尬和挫折:体育课老是不及格, 总被女孩们嘲笑,更不敢当众发表意见.幸而由于祖母的鼓励,我不在消极人生,而是充满 自信.她曾经说过:"孩子,如果体形无法改变,为什么不把它看做自己独特的风格呢?" 我开始这样来审视人生,通过改变生活的视角,我信心大增地去改变我的人生,很快就发现 一个崭新的世界. 朋友们,将信念,希望,爱意和忍性溶入生命,你就会找到自信,克服缺点,迎接 人生新的挑战.最后我的演讲包括在内,希望你会看到一场精彩的演讲比赛. 大学生英语演讲稿 16 十六, 杨颖,21 岁,海南 The East and the West, Let's enjoy the combination of the two cultures? Kipling said:"East is east, and west is west, and never the twain shall meet!" But now, a century later, they have met. 爱思英语学习网 爱思英语 - 中国最受欢迎的英语学习网站 - / 3 They have met in business. They have met in education. They have met in the ar ts. Some people will argue that these meetings will leave us with a choice between east a nd west, but I believe that the best future lies in the creative combination of both worlds. We can make western ideas, customs and technology our own, and adapt them to our o wn use. We can enjoy the best of both worlds, because our tradition is, above all, one of selecting the best and making it our own. I love Beijing and Hennan opera because it always reminds me of who I am. But I am also a fan of pop music, especially English songs. So I have combined eastern mel ody with western language. It is called western henna opera. When two cultures meet, there may be things in one culture, which do not fit int o the tradition of the other. When this happens, we need to learn to understand and respe ct the customs of another culture. Then there are certain things some people may not like. To this, I will say, if you do not like it, please try to tolerate it. To learn to tolerate w hat you personally don't like is a great virtue at a time when different cultures mix and merge. Before us, there are two rivers, eastern and western cultures. At present, they may run in different courses. But eventually, they will converge into the vast sea of human c ulture. Right now, I can see peoples of eastern and western cultures, standing side by sid e, singing the

Olympic theme song: we are hand in hand, heart to heart, together we will shape a beautiful tomorrow! Thank you! 让我们共同感受东西方的融合 吉卜林说过:东方是东方,西方是西方,二者永不相聚.但是一个世纪后的今天,东 西方相汇了! 它们相聚在经济领域,它们相聚在教育领域,它们相聚在艺术的殿堂.有人争 论说:这种融合需要我们在东方和西方之间做出选择,但我却坚信最美好的未来在于东方和 西方创造性的融合.我们可以将西方的思想,观念和技术变为我们自己所用的东西. 我喜爱京剧和河南豫剧,因为它们经常使我想起自己是谁.但我也热衷于流行音乐, 特别是英文歌曲. 于是我将东方的旋律和西方的语言结合到了一起, 它叫做西方版的河南豫 剧. 当两种文化相结合的时候, 也许一方的文化中的某些东西不适应另一方的传统文化. 当此种情况出现时,我们需要试着理解并接受另一种文化中的风俗习惯.然而,也许有些东 爱思英语学习网 爱思英语 - 中国最受欢迎的英语学习网站 - / 4 西你并不喜欢,对于此,我可以说,如果你不喜欢它,请试着去容忍它.当两种文化融合的 时候,试着去容忍你个人不喜欢的东西是一种美德. 在我们面前有两条河流,东方文化和西方文化.现在,它们也许正朝着不同的方向 流去.但是最终它们将汇合到人类文化的海洋里. 就在此时此刻,我看见东方和西方的人肩并肩的站在一起,高唱奥林匹克主题曲: 我们手拉手,心靠着心,共同创造美好的明天! 大学生英语演讲稿英语风采大赛半决赛选手自备演讲赏析(大学成人组) 十五, 黄扬,21,福建 Farewell, Indifference Who was the most well-known figure in China last month? It's Ma JiaJue—the c ollege student who murdered 4 of his roommates. Many people attributed his crime to his poverty and deficient education. In my opinion, his crime also has much to do with his classmates' indifference. Indifference is a terrible disease in today's colleges and the whole society. It's not rare that two students who have studied together for 4 years have never spoken to each other. It's not rare that a student who has been absent from class for several days is not noticed at all. It's also not rare that a student who has severe psychological problems is not cared about at all. Some people may say 'What the students with psychological problems like Ma Jia Jue need is not care but psychotherapy." However, when people are ill, what they need m ost is not only medical treatment, but also care from people around them. Every smile an d every caring word will bring sunshine to their life. I once heard one of my roommates who was an introverted girl sobbing at mid-ni ght. Being afraid of disturbing her, I sent a text message to comfort her. The next day, s he told me that she was crying for not being invited to one of her friend's birthday party. She thought she was neglected by others. But my message was really comforting which told her someone still cared about her. What can we do to prevent the tragedy of Ma JiaJue from happening again? Som e people may say 'Let's open more psychological courses in schools.' and other people m 爱思英语学习网 爱思英语 - 中国最受欢迎的英语学习网站 - / 5 ay say 'Let's donate more money for the poor students.' But I'll say "My fellow student, let's give more love and care to our roommates, our classmates and every person around us!" 走出冷漠 谁是中国上个月最有名的人物? 这当然要数马加爵了——这个杀害了四名同学的大 学生. 很多人将他的犯罪归结于他的贫穷和不全面的教育. 但我觉得他的犯罪还跟他周围同 学的冷漠有很大关系. 冷漠是流行于当今校园及整个社会中的一种可怕的疾病.有的同学在一起学习了 4 年却从未说过话, 有的同学几天没去上课却无人知晓, 还有的同学有了严重的心理问题却得 不到关心. 有人说:像马加爵那样有心理问题的人需要的不是关心而是心理治疗.但在一个人 生病的时候,除了医生的治疗,他需要的还有周围人的关心.一个微笑,一声问候都能为他 们的生活带来阳光. 有一天{两分钟英语演讲稿范文}.

半夜,我碰巧听见寝室里一个平时很内向的女孩在轻声抽泣.为了不惊动她, 我给她发了一条短信来安慰她. 第二天, 他告诉我那晚她哭了是因为她的一位好朋友开生日 聚会没有请她参加,她觉得自己被大家所忽视了.但我对短信却给了她很大安慰,让她觉得 还是有人惦记着她的. 如何才能阻止马加爵的悲剧重演呢?有人呼吁应该在学校开设更多的心理辅导课 程,有人建议应该给贫困学生更多的捐助,而我要说的是:同学们,让我们把更多的关爱带 给我们的舍友,同学和身边的每一个人! 大学生英语演讲稿 14 I Am Tripping My Elephant Here 十四, 郭峰,22 岁,宁夏 I Am Tripping My Elephant Here Once upon a time, a weenie ant was walking on his way. As he was walking, su ddenly he felt the ground shaking terribly. He looked around with his paranoid eyes and saw an elephant walking right behind him. Quickly, the little ant covered himself with dir t, but one leg was unfortunately left out. A sparrow saw everything, so she flew down wi th the purpose of teasing the ant: "Hey, chicken! Watch out your leg, it's out!" The ant f 爱思英语学习网 爱思英语 - 中国最受欢迎的英语学习网站 - / 6 elt embarrassed at first but then calmly responded: " Shi…I am going to trip that elephan t." Right now, I'm standing on this glamorous stage. But everything here reminds me of is a not so fun memory. Around this time last year I was in Nanjing competing in a nother speech contest. That was the first time for me to be in such a large event. Of cou rse the pressure I was under was immense too. After a sleepless and stressful night, I we nt onto that stage without the feeling in my legs. That speech turned out to be horrible. I don't remember how I get down from there, but I do remember afterwards I just wanted to find a hole to hide in just like the ant in the story. Back at my school, it took a lon g time for me to recover. Thanks to all the help I got from my special friends. My confi dence was restored. After rounds of giving speeches and answering tough questions, I am here today. From all that I've been through I've learned that a good future is based on a forgotten past, if I want my life to go on well I have to let go of my past failure. So t oday, with out fear, I am tripping my elephant again. 我又一次在绊大象 从前,一只小蚂蚁在路上走着,走着走着,忽然感觉到地在颤动,回头一看是一只 大象正朝他走来. 于是他很快用土盖住身体, 不幸一只脚忘在了外面. 一只麻雀看到了一切, 她飞下来想要取笑一下这只蚂蚁,说:"咳,胆小鬼,小心你的脚,露出来了!" 蚂蚁开始 有些尴尬,但一会不紧不慢地告诉麻雀说:"小声点,我要在绊那只大象." 今天,我站在这个讲台上.但周围的一切让我想到的却并不是一段有趣的回忆.大 概是去年的这个时间,我在南京参加另一个全国英语演讲比赛.那是我第一次参加大赛,当 然压力非常大. 经过压抑无眠的一整夜, 我走上了演讲台. 那时我有史以来最差的一次演讲. 我不记得自己怎么从讲台上走下来的, 只记得当时很想找一个地方躲进去再也不出来就想我 故事中的蚂蚁.回到学校,我花了好一段时间才恢复过来.幸好有朋友和老师的鼓励,我又 一次有了勇气和信心.经过一轮又一轮的演讲和回答问题,我今天站在了这里.让也我领悟 了一个道理: 一个好的将来是建立在忘掉过去的基础上的, 直到真正忘记过去的失败生活才 会变的美好.今天,我没有惧怕,又一次站到了大象的面前. 大学生英语演讲稿 13 Hold Fast To Your Dreams 十三, 张晶晶,21 岁,山西 Hold Fast To Your Dreams 爱思英语学习网 爱思英语 - 中国最受欢迎的英语学习网站 - / 7 I have a dream today. I have a dream that one day every vally shall be exalted, every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight, and the glory of the Lord shall be revealed, and all flesh shall see it toge ther. Wow, what a dream it has been for Martin Luther King. But the changing

world seems telling me that people gradually get their dreams lost somehow in the process of gr owing up, and sometimes I personally find myself saying goodbye unconsciously to those distant childhood dreams. However, we meed dreams. They nourish our spirit; they represent possibility even when we are dragged down by reality. They keep us going. Most successful people are dreamers as well as ordinary people who are not afraid to think big and dare to be great. When we were little kids, we all dreamed of doing something big and splashy, somethin g significant. Now what we need to do is to maintain them, refresh them and turn them i nto reality. However, the toughest part is that we often have no ideas how to translate th ese dreams into actions. Well, just start with concrete objectives and stick to it. Don't let the nameless fear confuse the eye and confound our strong belief of future. Through our talents, through our wits, through our endurance and through our creativity, we will mak e it. Hold fast to dreams, for if dreams die, life is a broken-winged bird that cannot fl y. Hold fast to dreams, for when dreams go, life is a barren field frozen with snow. So my dear friends, think of your old and maybe dead dreams. Whatever it is, pick it up an d make it alive from today. 抓牢你的梦想 我今天有一个梦想. 我梦想有一天,幽谷上升,高山下降,崎岖之地变平原,曲折之路成坦途.圣光展 露,满照人间. 这对马丁路德金是怎样的一个梦想啊.不过这个变化着的世界似乎在告诉我,在成 长的过程中, 人们却不知不觉把他们的梦想弄丢了, 而我自己也有时会觉得在告别很多童年 的梦. 爱思英语学习网 爱思英语 - 中国最受欢迎的英语学习网站 - / 8 然而,我们是需要梦想的.梦想滋养我们的灵魂,梦想代表着我们被现实拉垮时依 然具有的希望.它鼓励我们不断前进.大多数成功人士都是梦想家,同时也是普通人,只是 他们敢于梦想敢于成就伟大.当我们还是孩子的时候,我们都梦想过做一番大事业,现在应 当做的就是保存好那些梦想,再度恢复它们,并将它们实现.不过最难的是我们通常不知道 怎样付诸实施.那么,就从最具体的目标开始,坚持去做吧.不要让那些莫名的恐惧迷惑了 我们的双眼,影响了我们对未来的信念.用我们的天资和智慧,用我们的耐力和创造力,我 们一定会实现梦想. 抓牢你的梦想,因为如果梦想死亡,生活就成了一只折断翅膀的鸟再也不能飞翔. 抓牢你的梦想,因为如果失去梦想,生命就成了一块覆盖着冰雪的贫瘠的冻土.亲爱的朋友 们,想想那些过去的或已经死去的梦想吧.不管是什么,重新将它捡起,并从今天开始让它 重生. 大学生英语演讲稿 12 Make Every Moment Count 十二, 刘懿,21 岁,重庆 Make Every Moment Count One night, I complained to my mom about the lack of time. Finally she said,"yo u are short of time just because you waste precious minutes on complaints and anxiety. T he point is, no matter how full your schedule is, if you try really hard, you can always f it in some thing more." It is the same with filling the jar. Even if you place a dozen fist-sized rocks and a bucket of gravel into the jar, there is still space for sand and water between the rocks and gravel. The lack of time is just the excuse for my negligence of every single minute. I b elieve that the great dividing line between success and failure can be expressed in six wo rds,"I did not have enough time."The fact is I do have exactly the same number of ho urs per day that were given to Helen Keller, Pasteur, Thomas Jefferson, and Albert Einste in. The point is I have never touched upon the real meaning of life which lies in snatchi ng, seizing and enjoying every minute of it. No idleness, no delay, no procrastination, no complaint! It is during my moments of complaining or hesitation that my destiny is shape d. Once I make full use of every moment, I believe that, my worries will be gradually c ut down

and other fun things for a kid. every child has a good and great father, and so do i. my dad played a very important

role in my daily life`````exactly speaking, in my past 16 years. my father always stands in the center of my life, from past till now and possibly{两分钟英语演讲稿范文}.

in the future. my family was rather poor when i was in my childhood. we didnt have our own house

and had to live in a shabby, small room rented from my fathers factory. the room

was so small that there was little space for people to walk. i didnt have my own bed

and had to sleep with my parents. this is terrible both for my parents and me. but father made this all different!he works very hard on his own business, now

we have our own 2 housese,surly,i have my own room.and he take our family so much

happiness, richer and richer. when i was little, i did everything with my dad. you could always find me sitting

on his knee or walking and doing everything with him. every night he would read me

a bed time story and make the voices of each character. i learnt a lot from my daddy. i learnt to never take things to seriously and to

always smile. years pasted, my father is over 45 now. it is time for me to look after him and

i am sure i will do and we will live an even better life. and i will say,i really

love you dad,cause you are the hero in my mind. thank you so much! say no to junk food good morning, everybody! boys and girls, please raise you hand if you don’t like fried chicken wings.(你可现场问问题) how about double cheese burger? raise you hands if you don’t like french fries. i can see so many people like fried chickens, double cheese burgers and french

fries.

now let me ask you one more question: raise you hands if you like junk food. i can see that nobody likes junk food. right? boys and girls, do you realize that the one you were in favor just now are junk

foods.

junk food is a slang word for foods with limited nutritional value.

foods that are high in salt, sugar, fat or calories and low nutrient content.

are junk foods.

boys and girls, listen up! junk foods may cause hypertension junk foods may increase various kinds of cancer, cardiovascular disease,

diabetes, and obesity boys and girls, i am not standing here to scare you eating healthy foods should start from the young so let us start from today let us say no to junk food boys and girls, it is not a matter how long you could live it is the quality of life that counts! god bless everybody! bye! ladies and gentlemen, good morning. it’s my great honor to be here and i am very happy to see you all. thank you

for being here. what i am going to talk about today is how to speak good english. english may be the most important factor in deciding which countries are leaders

in the future. the language of the most advanced management and technology is

undoubtedly english. being able to absorb this information is really the key to the

new century. in the 21century. we can’t go there and speak our own language because

nobody is going to learn it in order to understand us. our asian rival, india, has surged ahead of other developing

countries in information technology because of its superior english skills. unless we are able to master english, we will not be able to get our population

to use it and take advantage of the new economy. there is an urgent need to have a

workforce which is proficient in the language in view of the information technology

onslaught.

{两分钟英语演讲稿范文}.

second, about learning english, i think laying a strong foundation is the first

and most important step. in other words, you should read and speak english every day.

memorizing new words and phrases is also helpful. of course, learning english takes

some time, so don’t be impatient. remember, rome wasn’t built in a day. and then

since english is not our native tongue, we must develop the muscles of your speech

organs to produce unfamiliar sounds. when you read, read as loudly as possible, as

clearly as possible and as quickly as possible. tongue muscles’ training is of

importance in learning any foreign language. every time you move your mouth, your memory will deepen, your muscles will

strengthen. you can make it. 关于梦想的2分钟英文演讲稿 my dream

a short speech. today my topic is youth. i hope you will like it , and found the

importance in your youth so that more cherish it. first i want to ask you some questions:

1、do you know what is youth?

2、how do you master your youth? youth

youth is not a time of life, it is a state of mind ; it is not rosy cheeks , red

lips and supple knees, it is a matter of the emotions : it is the freshness ; it is

第六篇 热核反应

能源是社会发展和进步的基石。如今,地球能源正面临严重短缺。煤、石油、天然气等天然能源矿藏的存量有限,随着人类多年的开采已经所剩无几。且不说这些宝贵的化工原料仅作为燃料使用所造成的极大浪费,就是谈到燃烧矿石燃料对环境所造成的严重污染和温室气体效应等后果,也让人们对直接消费这些天然能源再三反思。长期以来,人类一直在苦苦找寻体量大、污染少的新能源,以维持人类社会的持续发展。自从原子弹被研制成功并显示其巨大的威力后,立即引起了科学界对开发这种新能源——核能的巨大兴趣。

6.1核能的利用

20世纪后半叶,核能的开发利用在世界范围内出现热潮,各种类型的核电站(也称作核反应堆)得到了异常迅速的发展。随着改革开放和国民经济发展的需要,我国也先后建成了数个核电站。但目前全世界所有核电站的原理,都是利用铀等大原子量的重核裂变成较轻的核而释放能量,也就是原子弹的反应机理。此类核裂变电站具有极大的运行安全风险和原料开采、处理以及反应后废料储藏、处理过程的极大核污染风险。15年前的乌克兰切尔诺贝利核电站、稍后的美国三里岛以及日本等都发生过极其严重的核事故灾难,至今还常有这些事故后遗症影响的报道见诸报端。其所依赖的核裂变原料铀不仅开采处理的过程非常困难和危险,就其在地球上的储量来说,也极其有限,因此,它远非是人们所希望的新能源。

而另一种核能,核聚变能,它很不同于我们在现存的核电站所利用的核能形式。正如现有核电站的发电机理是原子弹爆炸一样,利用核聚变能所建成的核电站的核能机理是热核氢弹。它是在当两个轻核聚合成一个较重的核时释放出巨大的能量。尽管同是核反应,聚变和裂变却有着极大的不同。由于要使两个轻核发生聚合必须克服巨大的排斥静电势,由实验资料得出,为使两个氘核相遇,它们间的相对速度必须大于每秒700公里,在如此高速下的氘核早已成为温度在5千万℃以上的物质的第四态——等离子体了。这也是我们把聚变称为热核反应的原因。{两分钟英语演讲稿范文}.

太阳是一个由高温等离子体组成的巨大能量源泉,它的光和热都是来源于经

久不熄的热核聚变反应。如果实现人工控制下氢元素的核聚变反应即受控热核反应,那么在地球上同样可以创造出一个个具有不竭能量的人造太阳。利用氢的同位素氘和氚的原子核实现核聚变的热核反应堆,人类在地球上可以建造类似于太阳上的热核聚变而放出能量的新能源装置。这种装置所提供的能源,不仅极少污染,而且廉价,资源无限,因此它是永久性解决人类能源问题的唯一途径,单靠海水为原料进行核聚变反应,就能满足人类100亿年的用电需求。

研究核聚变有两种途径,一种是磁约束类型,一种是惯性约束类型,托卡马克属于前者。50多年来,全世界共建造了上百个托卡马克装置,其中包括中国建造的大小不等的十多个此类装置。随着装置技术性建设的发展和实验结果的推动,科学家和工程师们追求先进形式的托卡马克装置,以获得更加理想的结果,更加接近核聚变反应堆的目标。全超导托卡马克的建造就是在这样的理念下应运而生的。

6.2托卡马克磁约束装置

聚变核反应是一种非常理想的潜在新能源,近年来,磁约束聚变在托卡马克类型的装置上取得了突破性的进展,从而开发聚变能的科学可行性终于在托卡马克上得到了证实。正因为此,一个国际热核聚变工程实验堆(ITER)正在进行工程设计,其聚变输出功率可达1500MW。

HT-7U超导托卡马克是国家“九五”大科学工程, 它是一个具有非园截面的大型超导托卡马克装置。纵场电源是一个大容量高稳定度全控整电源,极向场电源满足建立等离子体和感应加热所要求的磁通变化及波形要求,并实现对等离子体电流、位移、形状和电流分布等的控制。

6.2.1核聚变与等离子体

质量数很小的两个适当的原子核在一定条件下重新组合成一个质量数较大的原子核,会释放出能量,这就是人类利用核能的另一重要途径即核聚变的理论依据。

1929年,有人提出太阳中产生能量的过程就是质子的聚变反应。这些反应能在温度高达15×106K的太阳中心发生。

聚变反应所需的原料直接或间接地都是氘核(D)。单位质量的氘聚变所放出的能量是单位质量235U裂变所放出能量的4倍左右。这是聚变核反应作为一

种潜在的新能源的突出优点之一。核反应是在原子核的热运动中发生的,所以称为热核反应,如果这种反应能够加以控制,则称为受控热核反应。计算得知温度达到108K-109K就可以发生聚变反应。要实现作为潜在能源的核聚变反应,只能通过高温等离子体的方法。在高温等离子体中氘核和电子处在几乎相同的高温状态中。而且,在等离子体中,氘核与电子作无规热运动,互相不断地碰撞着。因此,可以说高温等离子体物理学是核聚变的理论基础。

作为一种能源的核聚变反应堆,不仅要求等离子体的温度必须高到使离子能够克服彼此之间的库伦斥力而相互碰撞发生聚变反应,并且要求从等离子体发生聚变反应中释放的能量必须大于用以产生和维持高温等离子体所需的能量。劳逊作了核聚变等离子体中的能量平衡计算,设等离子体的密度为n,加热到温度T,该高温等离子体维持时间为τ。对于氘氘(D-T)反应,当等离子体温度为10keV时,实现能量收支平衡的nτ值是1020m-3s,如果实验上达到了劳逊判据要求的参考值,那就证明了核聚变的科学可行性。当Ti=30 keV时,nτ大约为

1.5×1020m-3s,达到了热核点火条件。

6.2.2磁约束托卡马克装置

核聚变等离子体温度极高,带电粒子的动能10 keV相当于温度108K(1eV=11600K)。磁约束就是利用磁场来将高温等离子体约束在一定的区域内(见图1),使之达到劳逊条件所要求的参数范围。

磁场对等离子体的约束能力在于磁场与等离子体之间有相互作用力。这些作用力包括三个方面,即磁场对等离子体中每个带电粒子的“洛伦兹力”;以及由此对等离子体产生的宏观效果磁应力;当等离子体中有电流通过时,除外加磁场产生的作用力外,电流本身产生的磁场还会产生一种箍缩力。

6.2.3 EAST全超导托卡马克完成首次工程调试

由我国自行设计、研制的世界上第一个全超导托卡马克 EAST(原名HT-7U)核聚变实验装置,于2月1日到3月17日成功进行了首次工程调试。本次工程调试的主要目的是检验主机的性能以及相关分系统的能力,探索未来可行的运行模式,测量主机和主要分系统的关键技术参数,验证各种安全保护系统的可靠性, 为年内成功运行提供必要的数据和积累经验。在调试中,最受关注的低温调试和磁体通电测试获得圆满成功。

在真空和低温条件就位后,从3月13日到3月得离子体所的相关人员对纵场磁体和12个极向场磁体分别进行了260 次通电测试。最长通电时间达到5000秒,最大电流达到8200安培,相对应的装置中心场强已达到2特斯拉。总控系统、真空系统、低温系统、数据采集系统、水冷系统、电源系统、装置技术诊断系统、失超保护、真空磁位形测量系统、超导传输线、高温超导电流引线、铜电流引线以及等离子体控制系统运行正常,保证了通电测试的安全和成功。

图3 EAST(原名HT-7U)全超导托卡马克实验装置

“EAST(原名HT-7U)全超导托卡马克实验装置”是国家“九五”大科学工程,其开工报告于2000年10月获国家发改委正式批准。EAST装置集全超导和非圆截面两大特点于一身,且具有主动冷却结构,它能产生稳态的、具有先进运行模式的等离子体,国际上尚无成功建造的先例。等离子体所的科技人员经过5年多的自力更生、自主创新和艰苦奋斗,在2005年底基本完成了主机总装以及各分系统的研制和安装工作。他们解决了包括大型超导磁体研制与测试等许多超导托卡马克建设过程中的重大科学和技术问题,获得了一系列具有自主知识产权的、可对国民经济产生重要作用的高新技术。EAST的建设使中国聚变研究向前迈出

了一大步,赢得了国内外同行的敬佩和高度关注。

6.3核聚变反应的研究和政治

随着中国、日本、韩国、俄罗斯、美国和欧盟6大ITER成员国6月28日在莫斯科敲定法国的卡达拉舍(Cadalache)为反应堆建设地,这一为期30年、共计投资将超过100亿欧元的国际超大型科学合作项目很快就将正式启动。“ITER”——拉丁文“道路”之意——是否真能为人类另辟蹊径,整个世界都在期待。酷暑严冬、暴风山洪„„被现代人类“剥削”的地球也在以自己的方式报复着人类。然而与生态气候所遭受的破坏相比,能源衰竭受到了更为广泛和急迫的关切。

实际上,宇宙中最常见的就是氢元素的聚变反应,所有的恒星几乎都在燃烧着氢。利用氢原子最容易实现的聚变反应是其同位素氘(读音刀,deuteri-um)与氚(读音川,tritium)的聚变。氘和氚发生聚变后,2个原子核结合成1个氦原子核,并放出1个中子和17.6兆电子伏特能量。每1升海水中含30毫克氘,30毫克氘聚变产生的能量相当于300升汽油,就是说,“1升海水等于300升汽油”。地球上海水中有45万亿吨氘,足够人类使用60亿年。ITER走向人间政治角力让ITER一波三折

事实上早在二战时期人类就早已实现了氘-氚聚变―――氢弹。但它比原子弹更具毁灭性和不可控性。如何将氢弹爆炸过程用人为手段大大减缓,其反应能量被缓慢而稳定地输出?这成为科学家们半个多世纪来为之奋斗的目标。

上个世纪50年代初,美国和苏联率先开始秘密地独立研究可控核聚变,然而随着研究的深入,理论和技术上遭遇的一个个障碍让各国认识到,只有开展广泛的国际合作才是加速实现核聚变能利用的唯一可行之路。热核聚变技术也成为冷战时期各国仍旧保持互通有无的特例。

1985年,美国总统里根和苏联领导人戈尔巴乔夫在一次首脑会议上提议,要求“在核聚变能方面进行最广泛的、切实可行的国际合作”。美苏两国首脑随后又与核技术领域处于领先地位的法国的总统密特朗进行了几次高层会晤,支持在国际原子能机构(IAEA)主持下,进行国际热核实验反应堆,即ITER的概念设计和辅助研究开发方面的合作。

1987年,IAEA邀请欧共体(欧盟前身)、美国、苏联、加拿大和日本的代表在维也纳开会并达成协议,五方合作设计建造国际热核实验反应堆,并由此诞生
