My Advice to Pessimists

1)disadvantages of pessimism

2)way(s) of overcoming pessimism

Sample 1

It is believed that pessimism often leads to hopelessness, sickness and failure, while optimism usually brings happiness, good health and success. Pessimists also make those around them very miserable. Therefore, pessimists should change their way of thinking and overcome the negative aspects of their personalities. Here are a few tips for them:

1. Try to smile more often. A smile has great power. It can chase sadness away. It will make you and other people feel happy. And it may even make things easier and better. Smiling in the morning makes a good beginning for the day. A smile is the most important sign of optimism.

2. Build up your self-confidence. Try to discover as many of your personal strengths as you can. Then write them all down. Read them several times when you are getting ready to do something or when you are facing difficulties. Your list will help you see your abilities.

3. Change your way of thinking. Don't always think that things will go wrong or that if they do there will be terrible results. Instead, convince yourself that things will improve and that you can work hard to help improve them. If you fail, think about what you have learned from the failure. If you succeed, praise yourself. Don't be too modest! There is nothing more encouraging than self-praise.

Try your best to become an optimist.

Sample 2

Are you an optimist or a pessimist? If you're a pessimist, here is some advice for you.

As everyone knows, pessimism is harmful to people. It makes you unhappy and unhealthy, and even brings depression, loneliness and failure. Pessimists tend to suffer more failures and setbacks because they don't believe they can succeed and thus don't struggle for it. Optimism, by contrast, can make you happy, healthy and successful. So it is good for you to change yourself from a pessimist to an optimist.

Here are some suggestions for you to become an optimist:

1. Remember that everyone experiences failures and disappointments. So when you fail, don't blame yourself too much. It may not be your fault.

2. When you fail in something, profit from the failure as a learning experience instead of getting depressed. And next time, you can make your plans to be more successful.

3. When you fail, don't be discouraged. Try again. Don't let negative thoughts hold you back. Just give yourself another chance. So never give up just because you failed.

Pessimism is harmful, but it can be changed. Trust yourself and try to adopt an optimistic attitude, and then you will be a winner in life more often.

“Burglar-proof doors and windows”

Directions: In China, many buildings are equipped with burglar-proof doors and windows.

What do you think of this phenomenon? Write a composition entitled “Burglar-proof doors and windows”to state your point of view. Your composition should include the following points:

1) Why do you think people install burglar-proof doors and windows?

2) Do you think it is useful? Why or why not?

3) Are there any other methods to prevent burglary? If so, what are they?

Burglar-proof Doors and Windows

Nowadays in China, more and more buildings are equipped with burglar-proof doors and windows, which becomes a special sight.

Some people install burglar-proof doors and windows because they want to avoid burglars. And some do so just because others do. If the first floor of one building has already been installed with burglar-proof doors and windows, then the second floor of the building

must be installed, too otherwise thieves can climb up along the burglar-proof windows and reach the second floor.

Do such windows and doors work? They may not be as useful as expected. Many burglar-proof windows and doors are not so solid or strong as we might think. On the other hand, these windows and doors are just like billboards which tell the thieves: “Come on, there are lots of valuable things in this room!”

And burglar-proof windows and doors cause many other problems. Everyday, people live in a cage confined with such doors and windows, they have less chance to communicate with their neighbors and improve the relationship between each other. If a fire break out, such doors and windows will be a real dangerous, which threaten people and prevent them from escaping.

In a word, installing burglar-proof windows and doors is not an effective and good way to avoid theft. In my opinion, we may use other methods such as build a neighbourhood burglar-proof systems with monitors, etc.

"Should learners aim to speak English with a native-speaker pronunciation?" Sample 1

In my opinion, there is no point in aiming to speak English with a native-speaker pronunciation. For most people, it is a waste of time.

First, language is a tool for communication among human beings. If people we meet understand what we are saying, that is all that is necessary. We do not need to imitate native speaker's pronunciation. In any case, there are many types of accents, so which one should we choose to imitate?

Second, the most important thing is how well we organize what we want to express. Our ideas should be clear and easy to understand. To do so, we should be able to use right words and correct grammar.

Third, given the fact that we live in China, it seems a little bit pointless for us to try desperately hard to get rid of our national accent in order to speak BBC English.

Finally, each of us has our own style when we speak. If we can give free rein to personal style, the English-speaking world will become more colorful and more interesting.

In a word, I prefer to speak with my characteristic and recognizable pronunciation, so long as listeners can understand me.

Sample 2

I think it is important to aim for native-speaker pronunciation. First of all, I think perfection is always a good goal in any aspect of language-learning. We aim for perfect grammar, so why not perfect pronunciation?

Second, the purpose of learning a language is to communicate with native-speakers or people from other parts of the world. The better my pronunciation is, the more easily they will be able to understand me. And I want people to understand me without any difficulty at all.

Third, given the fact that we live in China, it seems a little bit pointless for us to try desperately hard to get rid of our national accent in order to speak BBC English.

Finally, each of us has our own style when we speak. If we can give free rein to personal style, the English-speaking world will become more colorful and more interesting.

In a word, I prefer to speak with my characteristic and recognizable pronunciation, so long as listeners can understand me.

Sample 3

Should learners aim to speak English with a native-speaker pronunciation? No, it’s not really necessary to speak English like a native. Because the most important function of language is to express one’s idea. Some English learners spend quite a lot of time getting their accent right. It’s good effort, but it should not be done with time that should be devoted to broadening their knowledge about the country and people. So long as you can make yourself clear, that is, so long you can communicate with no problem, your English is good enough.

“Should Animals Be Trained to Help Humans?” or “Give Animal Their Freedom”

“Should Animals Be Trained to Help Humans?

In my opinion, animals should be trained to help humans. Though man is cleverer than animals, there’s still something animals can do for man.

First, animals are prior to man in some certain aspects. So man can train these animals to serve us. For instance, a pipe that is crooked and thin in your kitchen is clogged. You can do nothing but turn to a trained guinea pig. It can easily solve the problem.

Second, trained animals can be good assistants, especially dogs. A trained dog is always a faithful guard. It stays at the gate all day time. At night when it is sleeping, even a slightest sound will make it up. So it’s really safe if you have a guard dog.

So trained animals are very helpful to humans. It’s no doubt that we should train animals to help us.

点评:

作者举出两点理由说明动物应该受驯来帮助人类,观点鲜明、条理清晰、表达流畅。

但也有两处典型错误需要纠正.

一、… animals are prior to man in some certain aspects. 最好改为… animals are

superior to man in some aspects; … sometimes animals can do better job in some aspects.

二、It’s no doubt that we should train animals to help us. 应该改为There is no

doubt that…

Animals Should Be Trained

There are a wide variety of animals in the world. And many of them are highly intelligent. So if we train some animals to work for human beings, we can save a lot of money and manpower.

First, some kinds of animals can be trained based on their capacity to do certain types of jobs better than humans. For example, since dogs have a superior ability to track down odors, we can train them to find illegal drugs, earthquake victims, or even ancient tombs

Second, some animals can even lend us their hands. The monkey is a good example.

Monkeys can be trained to learn to open doors, fetch tools, bring books, etc. So they can help those who cannot move about freely because of some physical problems. Monkeys make the lives of these people happier and more comfortable.

Finally, in some cases, using animals not only saves money but also trouble. Using dolphins as underwater guards can be better and cheaper than any man-made tracking devices.

In a word, animals should be trained to help humans. If we train animals in the proper way, both humans and animals can get along very well.

Give Animals Their Freedom

Humans and animals are both creatures of nature, so we are equal. We have no right to take advantage of them. However, many animals are now being trained to work for us. Monkeys are trained as servants, dogs as hunters and sniffers, and dolphins as soldiers.

Beasts should be allowed to run freely over great distances and birds, fly freely in the blue sky. When they are in nature, they are active and able to live a normal life. But when they are kept in captivity, they are bored and frustrated.

If we have the right to choose our fate, so do animals. So when we force them to serve us, they have no freedom and are like slaves. What’s more, a lot of animals lose their lives when they help humans. But most humans don't care about their lives at all. As we know, life belongs to us only once and therefore is priceless, and it is also true with animals. But we show no mercy to animals when they have done so much for us. We are cold-blooded creatures and we should criticize ourselves.

In brief, we should treat animals in the same way we treat other people. Give animals their freedom.

Why you think it is important or interesting to travel

Traveling Is Wonderful

In school we always study hard and rarely have time for play and relaxation. During our vacation, we can do what we like. Some students go swimming, watch TV, go to the cinema, etc. But all I want to do is to travel.

Traveling is interesting. You can see a lot of fascinating things and you can learn about history. Three years ago, I went to Beijing. When I was in the Summer Palace, I walked through the famous Long Corridor, admiring the beautiful pictures drawn on it. In the Imperial Palace, I saw a lot of rare treasures I had never seen before. I went to the Great Wall as well as the Ming Tombs. After visiting these famous places, I can’t help feeling proud of my great motherland.

I think it is important to travel to different countries, if possible, so that you can learn about different cultures and customs. It can widen your knowledge of the world. In addition to learning new things, you can also discover the beauty of nature by yourself. When you are on the top of a mountain, you can breathe fresh air, you can see green scenery below and you can hear the sounds of nature. It is a very wonderful feeling.

Now Id like to invite you to go on a trip with me. Can you refuse?

I Enjoy Traveling

I enjoy traveling. I even consider it as a part of my life. When winter vacation approaches, the question for me to ask is not whether I should travel but where I should travel.

I find traveling can do me a lot of good when I look back on my trips. Traveling brings me knowledge and pleasure. It puts me in a good mood. When I go back to my studies, I work more happily.

As for knowledge, traveling helps me learn a lot about local customs and it broadens my views. Three years ago, I went to the “European City”in Wuxi, where there are many models of European architecture. During that trip I learned

something about Europe. Sometimes, traveling can bring me unexpected pleasure, too. Last year, two friends and I went to a small town near the Tai Mountain. The fact that the town had beautiful scenery and low expenses made us overjoyed.

Traveling is uplifting because it is relaxing and we can get rid of our anxiety and stress during the trip. If we travel together with our friends, we can improve our friendship through the shared experience. We can also meet new people and make new friends.

In the future, I plan to do more traveling.

"Which Has Had More Influence on You, Heredity or Environment?" Sample 1

I both benefit and suffer much from heredity. A short stout figure, an introverted personality, and unimaginative but rational mind: all of these traits come from the genes passed on to me from my parents. But family, schools, and society work together to shape what I am today.

My parents are both sport lovers, which makes me fond of physical exercises and turns my frame into a strong body. My honest parents punish me severely whenever I lie or make empty promises, thus I've learned the importance of personal integrity. At school I've learned to help others, to care for others and also to improve my reasoning and understanding skills. Learning about various positive and negative examples of behavior from the media and other sources of information, I have set my own moral standards regarding what to do and what not to do, what to like and what to hate.

Environment can change a person completely no matter where he was born and what he genetically inherited from his parents.

I always believe that a person can succeed in doing anything he feels interested in. Your environment provides all sorts of opportunities and the things necessary for your personal pursuit and achievement.

Sample 2

I benefit and suffer much from heredity. A short but stout figure, an introvert but sincere personality, and unimaginative but rational mind: all of these traits come from the genes passed on to me. But family, schools, and society play the most important role in my life.

My parents are both blue-collar workers, which makes me fond of physical exercise and turns my big frame into a strong body. My honest parents punish me severely whenever I lie or make false promises, thus I’ve learnt the importance of personal integrity. In school I’ve learned to help others, to care for others and also to improve my reasoning and understanding skills. Learning about various good and bad examples of behavior from the media and other sources of information, I am able to set up my moral system of what to do and what to hate.

Environment can change a person completely no matter where he was born and what he inherited from his parents. I always believe that a person can succeed in doing anything he really

wants to do. Your environment provides all kinds of opportunities and necessary things throughout your life.

Sample 3

Which has had more influence on you, heredity or environment? This is a difficult question to answer.

First, let us examine the influence of heredity. All my classmates call me "Fat Yu" because I am fat. My father is also fat, so I can't help connecting my fatness with his! Although I can't be absolutely sure that it comes from my father, I do think that I probably have a gene which he passed on to me and which determines my body build or shape.

Aside from that gene, my father gave me many excellent qualities. For example, I think I am good at abstract thinking. My father is an engineer and he often tells me that he was very good at Math and Physics at middle school and college. So thanks to these genes of his I got into this university.

However, I have many other characteristics, which may come from the environment I grew up in. For example, my father and mother are conservative and traditional. They lack a spirit of adventure and they have a hard time understanding many of the new things in China today. I, on the contrary, have the desire to explore and I hope I can become a pioneer of reform. I often have many original thoughts and ideas. All changes taking place around me whet my appetite for exploration.

In conclusion, I think both heredity and environment have influenced me greatly. Heredity created me, but environment has improved me.

Although I can’t be absolutely sure that it comes from my father, I do think that I probably have a gene which he passed on and which controls my shape. I have studied Genetics for a long time and more and more facts prove that there is a gene which controls fat in your body. So now I am convinced that I got a “fat”gene from my father.

Aside from that gene, my father gave me many excellent qualities. For example, I think I am good at abstract thinking. My father is an engineer.

In conclusion, I think both heredity and environment have influenced me greatly. Heredity created me, but my environment changes me.

“The Power of Music”

Music is the universal language of mankind. Music is everywhere. We can hear it in restaurants, airports, railway stations, supermarkets, department stores, banks, hospitals, and many other public places. Music of all kinds is now available, and tapes and CDs are not very expensive.

Music plays an important role in our everyday lives. Music can express emotions that are beyond speech and give us a better feeling about ourselves and about everything around us. It can change our attitudes towards many things.

When we feel sad, music is moonlight in the gloomy night of life which can cheer us up; when we are tired and bored, music can make us relaxed, it has charms to soothe the savage breast, to soften rocks, or bend a knotted oak. When we are working or studying, music can provide us with a pleasant environment so that we can work or study more efficiently. Music can make people work faster and with more energy. The best, most beautiful, and most perfect way that we have of expressing a sweet concord of mind to each other is by music. Music can also lull the babies to sleep and can even make cows produce more milk. In a word, music is irresistible and life without music would be boring and monotonous.

The Virtues of Being Young and Being Old

Sample 1

Being young is a wonderful thing. We are always trying to find ways to keep ourselves young for as long as possible. When we compliment someone on their young appearance, they will feel proud and happy. Why is youth so preferred or favored? It's because youth is the bright and colorful scenery of life. Young people have glorious ideas and are full of dreams. They have energy, time and optimism. Youth is a time for realizing dreams. Looking back on one's youth will bring the finest memories.

Being old is also wonderful. The aged are respected by society. They have experience so people turn to them when they are in trouble or when they need advice. Old people are a source of knowledge and experience for the young. Although they dream less than before, they're more confident about themselves thanks to their knowledge and experience. Those who worked hard when young will be able to appreciate their achievements and keep good memories of their past.

Being young, we must take every opportunity to improve ourselves so that when we are old, we will have no regrets about our youth.

Sample 2 The Virtue of Being Young and Being Old

Man’s youth is a wonderful thing. We are always trying to find methods to keep ourselves young forever. When you compliment someone on his young appearance, he will feel proud and happy. Why is youth so magical? It’s because youth is the bright and colorful scenery of life. Young people have glorious ideas and struggle to attain them. They have energy, time and all the optimism in the world. Youth is a time for fulfilling dreams. Thinking back on one’s youth will bring the finest memories.

Being old is also wonderful. The aged are respected by society. They have experience so people turn to them when they are in trouble or when they need advice. Old people are a source of knowledge and experience for the young.

Being young, we must take every opportunity to improve ourselves so that when we are old, we will have no regrets about our youth. (151 words)

Sample 3 The Virtues of Being Y oung and Being Old

Life is strange and at different phases of your life you can do and enjoy different things. When you are young, you learn to understand the meaning of life. When you are old, you see life more clearly and enjoy what you have achieved before. There are many differences between young people and old people.

Young people are equipped with a good memory and strong muscles to gain knowledge and experience. They can learn lots of things whenever they desire. Youth is the most important part of a person's life. Young people are vigorous and energetic, though they tend to be impulsive. They face challenges with passion and are open to new things. They are unwilling to stay in the same place and always want to keep moving. It won't take long for them to recover from disappointing failures, especially when they can get encouragement and advice from people around them. It seems natural for them to make great progress in their studies and work.

The advantage of being old is that your strength lies in your knowledge and experience. Old people can do things quickly without too much energy or vigor and it won't take them too long to come up with a reasonable decision. Their most important virtue is that they can teach the young how to do things well or how to be successful, and how to avoid unnecessary loss or failure. Those who are concerned with young people are always respected by others. Young people hope they'll be able to know the world as the old do sooner or later.

So if we are positive, we can always feel good about ourselves whether young or old.

(工作分析)计数器工作原理的模式化分析

(工作分析)计数器工作原理的模式化分析

计数器工作原理的模式化分析 时序逻辑电路是《脉冲和数字电路》这门课程的重要组成部分,计数器是时序逻辑电路基础知识的实际应用,其应用领域非常广泛。计数器原理是技工学校电工电子专业学生必须重点掌握的内容,也是本课程的考核重点,更是设计计数器或其他电子器件的基础。 但近年来技校学生的文化理论基础和理解能力普遍较差,按照课件体系讲授计数器这个章节的知识,超过70%的学生听不懂。 我先后为四届学生讲授过这门课,于教学实践中摸索出壹套分析计数器的方法——模式化分析,即把分析步骤模式化,引导学生按部就班地分析计数器。用这种方法分析,我只要以其中壹种计数器(如异步二进制计数器)为例讲解,学生便能够自行分析其他计数器。 教学实践证明,用这种方法讲授计数器知识,学生比较感兴趣,觉得条理清晰,易于理解,掌握起来比较轻松。这种方法仍有壹个好处,不管是同步计数器仍是异步计数器,不管是二进制计数器仍是十进制计数器,不管是简单的计数器仍是复杂的计数器,只要套用这种方法,计数器工作原理迎刃而解。即使是平时基础很差的学生,只要记住几个步骤,依葫芦画瓢,也能把计数器原理分析出个大概来。 一、明确计数器概念 分析计数器当然要先清楚什么是计数器啦。书上的概念是:

计数器是数字系统中能累计输入脉冲个数的数字电路。我告诉学生,计数器就是这样壹种电子设备:把它放于教室门口,每个进入教室的同学均于壹个按钮上按壹下,它就能告诉你壹共有多少位同学进入教室。其中,每个同学按壹下按钮就是给这个设备壹个输入信号,N个同学就给了N个信号,这N个信号就构成计数器的输入CP脉冲,计数器要统计的就是这个CP脉冲系列的个数。当然,如果没有接译码器,计数器的输出端显示的是二进制数而非十进制数,比如有9位同学进入教室,它不显示“9”,而是显示“1001”。 随后,我简要介绍了计数器的构成和分类,且强调,计数器工作前必须先复位,即每个触发器的输出端均置零。 二、回顾基础知识 分析计数器要用到触发器的关联知识,其中JK触发器最常用,偶尔用到T触发器和D触发器。因此,介绍完计数器概念后,我不急于教学生分析其原理,而是先提问JK、T、D触发器的关联知识,包括触发器的逻辑符号、特性方程、特性表等。 由于计数器的控制单元由逻辑门电路构成,分析前仍要简要回顾壹下和、或、非等常用逻辑门电路的关联知识。另外,用模式化方法分析计数器仍要用到逻辑代数的运算方法、逻辑函数的化简方法等关联知识。 三、画出解题模板 准备工作做完了,下面进入核心部分——列出分析计数器的

计数器原理分析及应用实例

计数器原理分析及应用实例 除了计数功能外,计数器产品还有一些附加功能,如异步复位、预置数(注意,有同步预置数和异步预置数两种。前者受时钟脉冲控制,后者不受时钟脉冲控制)、保持(注意,有保持进位和不保持进位两种)。虽然计数器产品一般只有二进制和十进制两种,有了这些附加功能,我们就可以方便地用我们可以得到的计数器来构成任意进制的计数器。下面我们举两个例子。在这两个例子中,我们分别用同步十进制加法计数器74LS160构成一个六进制计数器和一个一百进制计数器。 因为六进制计数器的有效状态有六个,而十进制计数器的有效状态有十个,所以用十进制计数器构成六进制计数器时,我们只需保留十进制计数器的六个状态即可。74LS160的十个有效状态是BCD编码的,即0000、0001、0010、0011、0100、0101、0110、0111、1000、1001[图5-1]。 图5-1 我们保留哪六个状态呢?理论上,我们保留哪六个状态都行。然而,为了使电路最简单,保留哪六个状态还是有一点讲究的。一般情况下,我们总是保留0000和1001两个状态。因为74LS160从1001变化到0000时,将在进位输出端产生一个进位脉冲,所以我们保留了0000和1001这两个状态后,我们就可以利用74LS160的进位输出端作为六进制计数器的进位输出端了。于是,六进制计数器的状态循环可以是0000、0001、0010、0011、0100和1001,也可以是0000、0101、0110、0111、1000和1001。我们不妨采用0000、0001、0010、0011、0100

和1001这六个状态。 如何让74LS160从0100状态跳到1001状态呢?我们用一个混合逻辑与非门构成一个译码器[图5.3.37b],当74LS160的状态为0100时,与非门输出低电平,这个低电平使74LS160工作在预置数状态,当下一个时钟脉冲到来时,由于等于1001,74LS160就会预置成1001,从而我们实现了状态跳跃。 图5.3.37b用置数法将74160接成六进制计数器(置入1001) 比这个方案稍微繁琐一点的是利用74LS160的异步复位端。下面这个电路中[图5.3.34],也有一个由混合逻辑与非门构成的译码器。 图5.3.34用置零法将74LS160接成六进制计数器

汽车启动电机的结构与工作原理

汽车起动机的结构与工作原理 前言在工作过程中就曾接触到汽车起动机,了解车辆对发动机起动机的工作要求,但是对汽车起动机的结构和工作原理并不清楚,借谭老师布置作业的这个机会,最近比较系统的查阅了汽车起动机的相关课件和参考书,了解了汽车起动机的结构及工作原理。汽车起动机由直流电机、传动装置和控制装置组成,直流电机没有特殊之处,比较容易理解,传动装置和控制装置结构较为特殊,本文重点整理了所查阅的汽车起动机的传动装置和控制装置的相关资料。 要使发动机由静止状态过渡到工作状态,必须用外力转动发动机的曲轴,使气缸内吸入(或形成)可燃混合气并燃烧膨胀,工作循环才能自动进行。汽车发动机常用的起动方式是用电动机作为机械动力,当将电动机轴上的齿轮与发动机飞轮周缘的齿圈啮合时,动力就传到飞轮和曲轴,使之旋转。电动机本身又用蓄电池作为能源。目前绝大多数汽车发动机都采用电动机起动。 起动机一般由直流电动机、传动机构、控制装置三部分组成。 图1 起动机 1.直流电动机 直流电动机在直流电压的作用下,产生旋转力矩。直流电动机主要由电枢、磁极、电刷、电刷架及壳体等部件组成。 1.1 电枢 电枢是直流电动机的转子部分,用来将电能转变为机械能,即在起动机通电时,与磁场相互作用而产生电磁转矩。

1.2 磁极 磁极是直流电动机的定子部分,用来产生电动机运转所必须的磁场,它由磁极铁心、安装在铁心上的励磁绕组及机壳组成。 1.3 电刷与电刷架 电刷用铜和石墨粉压制而成,一般含铜80%~90%,石墨10%~20%,以减小电刷电阻并增加其耐磨性。一般起动机电刷个数等于磁极个数,也有的大功率起动机电刷个数等于磁极个数的2倍,以便减小电刷上的电流密度。 2.传动装置 普通起动机传动装置中的主要组成部件是单向离合器,单向离合器的作用是起动时将电枢的电磁转矩传递给发动机飞轮,而在发动机起动后,就立即打滑,以防止发动机飞轮带动起动机电枢高速旋转而损坏起动机。起动机单向离合器常见的有滚柱式、摩擦片式、扭簧式等几种形式。 2.1滚柱式单向离合器 (1)结构特点 滚柱式单向离合器的外壳2与驱动齿轮1连为一体,外壳和十字块3装配后形成四个楔形槽,槽中有四个滚柱,滚柱的直径大于槽窄端又小于槽宽端,弹簧将滚柱推向槽窄端,使得滚柱与十字块及外壳表面有较小的摩擦力。十字块与传动套筒8刚性连接,传动套筒安装在电枢轴花键部位,使单向离合器总成可作轴向移动和随轴转动。 图2 滚柱式单向离合器 (2)工作原理 起动时,电枢轴通过花键带动传动套筒而使十字块转动,十字块相对于外壳作顺时针转动,使滚柱在小摩擦力的作用下滚向槽窄端而被卡紧,外壳即随十字块一起转动,电动机的电磁转矩便通过单向离合器传递给了驱动齿轮。发动机一旦发动,发动机飞轮

光谱仪的原理、功能以及分类【详尽版】

光谱仪的原理光谱仪的主要功能以及具体的分类 内容来源网络,由SIMM深圳机械展整理 更多相关展示,就在深圳机械展! 光谱仪器是进行光谱研究和物质结构分析,利用光学色散原理及现代先进电子技术设计的光电仪器,光谱仪的主要功能是什么,在它工作原理的基础上怎么对其进行分类的,本文将详细的为大家介绍。 光谱仪的主要功能 它的基本作用是测量被研究光(所研究物质反射、吸收、散射或受激发的荧光等)的光谱特性,包括波长、强度等谱线特征。因此,光谱仪器应具有以下功能: (1)分光:把被研究光按一定波长或波数的发布规律在一定空间内分开。 (2)感光:将光信号转换成易于测量的电信号,相应测量出各波长光的强度,得到光能量按波长的发布规律。 (3)绘谱线图:把分开的光波及其强度按波长或波数的发布规律记录保存或显示对应光谱图。 要具备上述功能,一般光谱仪器都可分成四部分组成:光源和照明系统,分光系统,探测接收系统和传输存储显示系统。 主要分类 根据光谱仪器的工作原理可以分成两大类:一类是基于空间色散和干涉分光的光谱仪;另一类是基于调制原理分光的新型光谱仪。本设计是一套利用光栅分光的光谱仪,其基本结构如

图。 光源和照明系统可以是研究的对象,也可以作为研究的工具照射被研究的物质。一般来说,在研究物质的发射光谱如气体火焰、交直流电弧以及电火花等激发试样时,光源就是研究的对象;而在研究吸收光谱、拉曼光谱或荧光光谱时,光源则作为照明工具(如汞灯、红外干燥灯、乌灯、氙灯、LED、激光器等等)。为了尽可能多地会聚光源照射的光强度,并传递给后面的分光系统,就需要设计照明系统。 分光系统是任何光谱仪的核心部分,它一般是由准直系统、色散系统、成像系统三部分组成,作用是将照射来的光在一定空间内按照一定波长规律分开。如图2-1所示,准直系统一般由入射狭缝和准直物镜组成,入射狭缝位于准直物镜的焦平面上。光源和照明系统发出的光通过狭缝照射到准直物镜,变成平行光束投射到色散系统上。色散系统的作用是将入射的单束复合光分解为多束单色光。多束单色光经过成像物镜按照波长的顺序成像在透镜焦平面上;这样,单束的复合光经过分光系统后变成了多束单色光的像。目前主要的色散系统主要有物质色散(如棱镜)、多缝衍射(如光栅)和多光束干涉(如干涉仪)。 探测接收系统的作用是将成像系统焦平面上接收的光谱能量转换成易于测量的电信号,并测

人们常说爱祖国,爱学习,爱劳动。节约用水,节约用电,节约粮食,然而真正做到的有多少人呢?鲜艳的五星红旗,在雄壮的国歌声中冉冉升起,我们又迎来了崭新的一天.如今有一种风气风行全国,有一种理念深入人心,“三节三爱”已成为一个惹人注目的信息,学校到处张贴“爱学习,爱劳动,爱祖国.节水,节电,节约粮食”的条形标语,我总是驻足观望,细心读来,每次读它都有新的感悟,它所提到的无疑是一种正能量,一种向上的能量,交给我们正确的人生观,荣辱观,同学们都应该带着它乘风破浪,勇往直前! 勤以修身,俭以养德,节约为美,勤俭节约是中华民族的传统美德.学习,是我们学生最大的责任和义务,学习是同本之举,是源头活水,庄子曰“吾生也有涯,而知也无涯”,知识是力量,学习改变命运,爱学习我们才能在知识的海洋徜徉,才能能为自信,自强,自立的一代青年.我们的祖先也有一句名言:劳动最光荣!我们现在的劳动无非就是帮父母扫扫地,擦擦桌子,在学校里整整桌椅,其实就是一件小事,“勿以善小而不为,勿以恶小而为之”.很多的善小都能使他人收益匪浅. 爱国是一种光荣,自始至终我们都为是一个中国人而自豪!我们的祖国有5000年文明历史,有960万平方公里.勤劳智慧的中华儿女共,同开拓了辽阔的疆域,创造了辉煌灿烂的文化.肩负着实现中华民族伟大复兴的我们,要热爱祖国的大好河山,积极维护祖国的主权独立和领土完整,祖国的领土寸土不能丢,不能被分裂侵占;要热爱祖国的历史和文化,提高民族自尊心和自信心,为创造更加辉煌的民族文

化而尽心尽力.“历览前贤国与家,成由勤俭败由奢”.这是历史上的有识之士从家族兴衰、社稷兴亡、朝代更替的无数经验教训中得到的一条深刻警示.近日党中央提出建设节约型社会,就是从这一警示中作出的一个事关国家长远发展和民族兴衰的战略举措. 节约是中华民族的传统美德,是我们民族世代相传的精神财富,也是我们这个民族百折不饶、生生不息的力量源泉.节约这种美德为世代中国人所崇尚.早在春秋时期,俭朴就作为一种公德,为智者仁人所大力倡导.《论语》中就有“夫子温、良、恭、俭、让以得之.”其中“俭”就是节俭.意思是孔子具有包括节俭在内的五种品德,所以能赢得人们的信任.墨子也极力主张要在衣、食、住、行、丧葬等方面“制为节用之法”.“节约”符合“天德”.奢侈浪费就是“亏夺人衣食之财”,侵害别人的生存权.《左传》中说:“俭,德之共也,侈,恶之大也”.把俭朴作为培养良好道德的基础,把侈奢看成是一切恶行的根源.诸葛亮在《诫子书》中说:“夫君子之行,静以修身,俭以养德,非淡泊无以明志,非宁静无以致远”.多少年来,在中国社会发展的各个时期,艰苦朴素、勤劳节俭都作为一种被社会普遍认同的传统美德,得到倡导、保持和发扬.这也是我国由小到大、由弱到强的重要因素. 在全社会大力倡导“节约”的传统美德,重在实践,贵在坚持.我们应牢固树立“以艰苦朴素、勤俭节约为荣、以铺张浪费、奢侈挥霍为耻”的荣耻观;每个家庭都要节约持家,不要铺张浪费,不超前消费;每个学生都要在工作学习生活中自觉弘扬节约的优良作风,养成节约一滴水、一度电、一张纸、一滴油、一粒米的良好习惯.只要我们每个人

实验室常用光谱仪及其它们各自的原理

实验室常用光谱仪及其它们各自的原理 光谱仪,又称分光仪。以光电倍增管等光探测器在不同波长位置,测量谱线强度的装置。其构造由一个入射狭缝,一个色散系统,一个成像系统和一个或多个出射狭缝组成。以色散元件将辐射源的电磁辐射分离出所需要的波长或波长区域,并在选定的波长上(或扫描某一波段)进行强度测定。分为单色仪和多色仪两种。 下面就介绍几种实验室常用的光谱仪的工作原理,它们分别是:荧光直读光谱仪、红外光谱仪、直读光谱仪、成像光谱仪。 荧光直读光谱仪的原理: 当能量高于原子内层电子结合能的高能X射线与原子发生碰撞时,驱逐一个内层电子而出现一个空穴,使整个原子体系处于不稳定的激发态,激发态原子寿命约为(10)-12-(10)-14s,然后自发地由能量高的状态 跃迁到能量低的状态.这个过程称为发射过程.发射过程既可以是非辐射跃迁,也可以是辐射跃迁. 当较外层的电子跃迁到空穴时,所释放的能量随即在原子内部被吸收而逐出较外层的另一个次级光电子,此称为俄歇效应,亦称次级光电效应或无辐射效应,所逐出的次级光电子称为俄歇电子.它的能量是特征的,与入射辐射的能量无关.当较外层的电子跃入内层空穴所释放的能量不在原子内被吸收,而是以辐射形式放出,便产生X 射线荧光,其能量等于两能级之间的能量差.因此,X射线荧光的能量或波长是特征性的,与元素有一一对应的关系. K层电子被逐出后,其空穴可以被外层中任一电子所填充,ad4yjmk从而可产生一系列的谱线,称为K系谱线: 由L层跃迁到K层辐射的X射线叫Kα射线,由M层跃迁到K层辐射的X射线叫Kβ射线同样,L层电子被逐出可以产生L系辐射.如果入射的X 射线使某元素的K层电子激发成光电子后L层电子跃迁到K层,此时就有能量ΔE释放出来,且ΔE=EK-EL,这个能量是以X射线形式释放,产生的就是Kα 射线,同样还可以产生Kβ射线,L系射线等. 莫斯莱(H.G.Moseley) 发现,荧光X射线的波长λ与元素的原子序数Z有关,其数学关系如下: λ=K(Z-s)-2 这就是莫斯莱定律,式中K和S是常数,因此,只要测出荧光X射线的波长,就可以知道元素的种类,这就是荧光X射线定性分析的基础.此外,荧光X射线的强度与相应元素的含量有一定的关系,据此,可以进行元素定量分析. 红外光谱仪的原理: 红外光谱与分子的结构密切相关,是研究表征分子结构的一种有效手段,与其它方法相比较,红外光谱由于对样品没有任何限制,它是公认的一种重要分析工具。在分子构型和构象研究、化学化工、物理、能源、材料、天文、气象、遥感、环境、地质、生物、医学、药物、农业、食品、法庭鉴定和工业过程控制等多方面的分析测定中都有十分广泛的应用。

计数器工作原理的模式化分析

计数器工作原理的模式化分析 时序逻辑电路是《脉冲与数字电路》这门课程的重要组成部分,计数器是时序逻辑电路基础知识的实际应用,其应用领域非常广泛。计数器原理是技工学校电工电子专业学生必须重点掌握的内容,也是本课程的考核重点,更是设计计数器或其他电子器件的基础。 但近年来技校学生的文化理论基础和理解能力普遍较差,按照教材体系讲授计数器这个章节的知识,超过70%的学生听不懂。 我先后为四届学生讲授过这门课,在教学实践中摸索出一套分析计数器的方法——模式化分析,即把分析步骤模式化,引导学生按部就班地分析计数器。用这种方法分析,我只要以其中一种计数器(如异步二进制计数器)为例讲解,学生便可以自行分析其他计数器。 教学实践证明,用这种方法讲授计数器知识,学生比较感兴趣,觉得条理清晰,易于理解,掌握起来比较轻松。这种方法还有一个好处,不管是同步计数器还是异步计数器,不管是二进制计数器还是十进制计数器,不管是简单的计数器还是复杂的计数器,只要套用这种方法,计数器工作原理迎刃而解。即使是平时基础很差的学生,只要记住几个步骤,依葫芦画瓢,也能把计数器原理分析出个大概来。 一、明确计数器概念 分析计数器当然要先清楚什么是计数器啦。书上的概念是:计数器是数字系统中能累计输入脉冲个数的数字电路。我告诉学生,计数器就是这

样一种电子设备:把它放在教室门口,每个进入教室的同学都在一个按钮上按一下,它就能告诉你一共有多少位同学进入教室。其中,每个同学按一下按钮就是给这个设备一个输入信号,N个同学就给了N个信号,这N 个信号就构成计数器的输入CP脉冲,计数器要统计的就是这个CP脉冲系列的个数。当然,如果没有接译码器,计数器的输出端显示的是二进制数而非十进制数,比如有9位同学进入教室,它不显示“9”,而是显示“1001”。 随后,我简要介绍了计数器的构成和分类,并强调,计数器工作前必须先复位,即每个触发器的输出端均置零。 二、回顾基础知识 分析计数器要用到触发器的相关知识,其中JK触发器最常用,偶尔用到T触发器和D触发器。因此,介绍完计数器概念后,我不急于教学生分析其原理,而是先提问JK、T、D触发器的相关知识,包括触发器的逻辑符号、特性方程、特性表等。 由于计数器的控制单元由逻辑门电路构成,分析前还要简要回顾一下与、或、非等常用逻辑门电路的相关知识。另外,用模式化方法分析计数器还要用到逻辑代数的运算方法、逻辑函数的化简方法等相关知识。 三、画出解题模板 准备工作做完了,下面进入核心部分——列出分析计数器的9个步骤: 1.驱动方程(即触发器输入端的表达式,注意要化成最简式) 2.特性方程(即触发器的特性方程,计数器有几个触发器就写出几个 特性方程) 3.状态方程(把1代入2后得到的方程,注意要化成最简式)

现代近红外光谱分析仪工作原理

现代近红外光谱分析仪工作原理 现代近红外光谱分析仪工作原理 2011年02月08日 20世纪90年代初,外国厂商开始在我国销售近红外光谱分析仪器产品,但在很长时间内,进展不大,其原因主要是:首先,近红外光谱分析要求光谱仪器、光谱数据处理软件(主要是化学计量学软件)和应用样品模型结合为一体,缺一不可。但被分析样品会由于样品产地的不同而不同,国内外的样品通常有差异,因此,进口仪器的应用模型一般不适合分析国内样品。如果自己建立模型,就需要操作人员了解和熟悉化学计量学知识和软件,而外商在中国的代理机构缺乏这方面的专业人才,不能有效地根据用户的需要组织培训,因此,用户对这项技术缺乏全面了解,影响到了它的推广使用。其次,进口仪器价格昂贵,售后技术服务费用也往往超出大多数用户的承受能力。 现代近红外光谱分析技工作原理 近红外光谱主要是由于分子振动的非谐振性使分子振动从基态向高能级跃迁时产生的。近红外光谱记录的是分子中单个化学键的基频振动的倍频和合频信息,它常常受含氢基团X-H(X-C、N、O)的倍频和合频的重叠主导,所以在近红外光谱范围内,测量的主要是含氢基团X-H振动的倍频和合频吸收。 由于倍频和合频跃迁几率低,而有机物质在NIR光谱区为倍频与合频吸收,所以消光系数弱,谱带重叠严重。因此从近红外光谱中提取有用信息属于弱信息和多元信息,需要充分利用现有的光机技术、电子技术和计算机技术进行处理。计算机技术主要包括光谱数据处理和数据关联技术。光谱数据处理是消除仪器因素(灯及测量方式等)环境因素(如温度等)和样品物态(如颜色、形态等)等对光谱的影响。常采用的方法有平滑、微分、基线漂移扣减、多元散射校正(MSC)和有限脉冲响应滤波(FIR)等也可以用小波变换来进行部分处理。数据关联技术主要是化学计量学方法。化学计量学的发展使多组分分析中多元信息处理理论和技术日益成熟,解决了近红外光谱区重叠的问题。通过关联技术可以实现近红外光谱的快速分析。在近红外光谱的应用中我们所关心的是被测样品的组成或各种物化性质,因此,如何提取这些有用信息是近红外光谱分析的技术核心。现在的许多研究与应用表明,
