汽车制动系统摘要最近开发汽车制动系统的创新激发人们对摩擦片和离合器鼓的摩擦状况的分析产生了新兴趣。
本文利用摩擦片和离合器鼓接触材料在不同的操作条件下的滑动摩擦的实验室装备获得实验结果。
利用人工神经网络来确定影响滑动摩擦的主要参数。
该研究还考虑到滑动加速度的重大影响，以改善这些干摩擦的设备的瞬态操作的摩擦系数预测。
1简介目前，乘用车都配备了越来越多的电子系统。
这是由于人们对驾驶舒适性，汽车的性能和减少燃料消耗的要求越来越多，另一方面由于人们对降低成本和提高汽车传感器的性能，微控制器和执行机构的职权范围的要求也越来越多[1]。
在车辆动力学的控制系统中，几个实验室实验的防抱死制动系统（ABS），防滑转控制系统（TCS）和电子稳定程序（ESP）表现出的潜力，进一步提高了仪器的性能[2,3]。
结果证明，刹车盘的摩擦状况的具体模型/盘相互作用的不稳定的工况,如突然制动或粗暴动作的电除尘系统/电子稳定系统对于获得突破的制动控制策略/稳定控制系统的连续和不循环调节是一个至关重要的课题[3]。
提供详细的摩擦示意图可以减少一个控制工程师的努力和时间校准系统。
同样，研究有关自动-手动变速器(AMTs)和双离合器变速器（DCTs）表明，进一步改进安全，舒适，换挡品质，同时减少燃料消耗和污染排放量能够实现。
为了达到这样的目标，一些基于对离合器接合的模型的控制策略最近已在文献中提出；然而，没有可靠的离合器转矩传播特性摩擦示意图对设计出有效的控制器是很困难的[4]。
也是在这一应用，摩擦综合示意图合理的减轻了耗时的校准工作。
以往的作品展示了材料承受的不同载荷，滑动速度，界面温度和材料成分如图[5,6]。
这些分析中的大多数主要是针对稳态测量的干摩擦滑动接触而分析的。
本文通过对刹车和离合器衬片的通用材料的摩擦状况的影响参数的实验结果进行了介绍。
商业离合器和刹车片的接触材料已用一个滑动装置测试。
一系列的短时间的实验已采用不同级别载荷和滑动速度的模拟操作条件。

WHY DO WE CELEBRATE FESTIVALS我们为什么庆祝节日？Festivals are celebrated all around the world. They have a wide range of origins, such as the seasons of the year, religions, famous figures, and important events. Every festival has its different customs and unique charms. However, no matter how different they may seem, all over the world, the spirit of sharing joy, gratitude, love, or peace is common in all festivals.世界各地都庆祝各种节日。
节日的由来五花八门，比如时节、宗教、著名人物及重要事件。
每个节日都有其不同的习俗和独特的魅力。
然而，无论它们多么迥异，在世界各地，分享快乐、感恩、友爱或和平的精神存在于所有节日之中。
Of all the traditional festivals, the harvest festival can be found in almost every culture. This important agricultural festival takes place after all the crops have been gathered in. People celebrate to show that they are grateful for the year’s supply of food. In ancient Egypt, the harvest festival was celebrated during the springtime—the Egyptianharvest season. It featured a parade and a great feast with music, dancing, and sports. Today, in some European countries, people decorate churches and town halls with flowers and fruit, and get together to celebrate over a meal. During the Mid-Autumn Festival in China, families gather to admire the shining moon and enjoy delicious mooncakes.在所有的传统节日中，丰收节几乎可见于每一种文化之中。

C1--arrangeuniversityhousing（文本）C1--arrange university housingNarrator: Listen to a conversation between a student and a Department of Housing employeeS: Hi, I’m a first year student and I’ve lived in student housing for the past 6 months. A classmate just told me that I might have missed the application deadline for the next academic year. I didn’t know I had to apply again so early. I thought I’d better stop by. Um, has that deadlin e passed?Employee: Well, housing is a three-stage process with a few different deadlines. One of the m is approaching soon, but none of them has passed yet. So you’re fine. S: Great! Oh, that’s a relief! Could you tell me then about what I need to take care of?Employee: Sure! For stage one, you only have until end of this week to do two things. First, you need to go to the university home page and complete the housing re-application online. And secondly, if that gets approved, you have to pay the $1,000 non-refundable housing deposit.S: Uh oh, I mean the $1,000 is not a problem, it’s the non-refundable part that…Employee: Well, what do you mean?S: (2)Well, it’s just that I don’t know yet precisely where I’ll be next year. I applied for the university’s s tudy abroad option, but they won’t make their decision for a few more months. So I do really need to plan for both possibilities, but if the $1,000 is non-refundable…Employee: Well, you still have to meet our re-application and deposit deadline to remain eligible for any future guaranteed housing. Otherwise, you’ll always be put on the waiting list.(3)However, the study abroad program is an exception to ournon-refundable policy. So if you get accepted into that program, you can submit a Study Abroad Notification Form to our office.S: But what will that do?Employee: That way, we can change your stat us. But you’ll still be eligible for future housing and the $1,000 will be credited to your account.S: Oh, okay.Employee: (4)Now, as part of stage two of the housing process, coming up in about a month, there’ll be an official open house session. It’ll provide students with an opportunity to visit the different student housing buildings. And also, to learn more about the surrounding communities. You know, si nce we’re a city college, some of those areas have different attractions which give each of them a different personality. Take Tremble Hall for instance, it’s right next to a Weekend Farmer’s Market. And there’s Clark Hall, which is on the same block as the Art Museum. Lots of options to explore.S: Great! I’ll plan to attend. And what about roommates? There’s two friends I’d like to live with. Can I arrange that?Employee: (5)Yes, the day after the open house, submit a roommate preference card. Make sure only one person submits all the information on one card. Now, we do the best we can do accommodate groups. However, please be aware as space becomes limited, individuals in the group may be placed in different locations.S: Got it! And what’s stage three?E mployee: That’s the final stage where you select the specific room that you’d like.。

新标准⼤学英语综合教程3课⽂summary↓↓↓⼤英3课⽂SummaryUNIT 11.1 catching crabsIn the fall of our final year,our mood changed.The relaxed atmosphere had disappeared, and peer group pressure to work hard was strong. Meanwhile,at the back of everyone’s mind was what we would do next after graduation. As for me,I wanted to travel,and I wanted to be a writer.I braced myself for some resistance to the idea from my father,who wanted me to go to law school,and follow his path through life.However,he supported what I wanted but he made me think about it by watching the crabs.The cage was full of crabs. One of them was trying to escape,but each time it reached the top the other crabs pulled it back.In the end it gave up lengthy struggle to escape and started to prevent other crabs from escaping.By watching crabs,my father told me not to be pulled back by others,and to get to know himself better.1.2We are all dyingLife is short.We never quite know when we become coffin dwellers or trampled ash in the rose garden of some local ceremony.So there’s no p oint in putting our dreams on the back burner until the right time arrives.Now is the time to do what we want to do. Make the best of our short stay and fill our life with the riches on offer so that when the reaper arrives,we’ve achieved much instead of regrets.UNIT 22.1supermanThe extract from Johnny Panic and the Bible of Dreams by Sylvia Plath is a combination of her real life and imaginary life in her childhood.In the real life,Plath was a winner of the prize for drawing the best Civil Defense signs,lived by an airport and had an Uncle who bore resemblance to Superman.In her imagination,the airport was her Mecca and Jerusalem because of her flying dreams.Superman fulfilled her dream at the moment.David Stirling,a bookish boy,also worship Superman.During the recess at school,he and the author played Superman /doc/15a6ccfc6394dd88d0d233d4b14e852458fb39dd.html pared with their school-mates who played the routine games,they felt they were outlaws but had a sense of windy superiority.They also found a stand-in,Sheldon Fein, who later invented tortures.2.2cultual childhoodsHistorically,childhood has undergone enormous transformations in terms of children’s responsibilities and parental expectations.Culturally,childhood is socially constructed.The interplay of history and cultural leads to different understanding of childhood,consequently it is advisable not to impose ideas from one culture to understand childhood in another culture.UNIT 33.1how we listenFor the sake of clarify,we split up the process of listening to music into three hypothetical planes.Firstly,the sensuous plane.It is a kind of brainless but attractive state of mind engenderedby the mere sound appeal of the music.Secondly,the expressive plane.It is when we believe each piece of music has a theme,which mirrors a different world of feeling,such asgaiety,sadness.Thirdly,the musical plane.It is the ability to experience different musical elements,such as melodies,the rhythms,the harmonies,the tone colors etc.We usually listen to music on all three planes.3.2the mystery of Girl with a Pearl EarringThe painting Girl with a Pearl Earring is one of Dutch painter Johannes V ermeer’s masterworks.It shows a striking young woman wearing an exotic costume and a turban,peering over her shoulder straight out at the viewer.As the name implies,it uses a pearl earring for a focal point.It has been referred to as the Mona Lisa of the north,because,like Leonardo da Vinci’s painting,it appears to be a simple likeness of a woman with an enigmatic smile,yet which contains levels of meanings andquestions.So much mystery in the painting contributes to its worldwide popularity and generates a thoroughly rewarding novel and a well-composed film.UNIT 44.1work in corporate AmericaIn today’s American jobs are not what they used to be.Not long ago,when a f ather was asked about his job he could answer in terms that a child could come to grips with.Nowadays,when the parent take his offspring to his place of business in glass buildings that are really incomprehensive to children.What’s more,it’s safe bet that even grown men have trouble visualizing what other men does in their jobs with his day.Therefore,it’s not difficult to imagine a poor child mayanswer”mulling over” after it beats me the mysteries of work,when his friends asks him of his father’s job.4.2our supposedly exciting times are really rather dullLiving in a world of unprecedented/dazzling change,there are never been anything quite likeit.However,we are just ignorant of/about deeper historical patterns,take globalization for example,from historical context point of view,the world is almost meaningless.We simply do not live in a age of great technological innovation for all our enthusiasm about internet and iPod.With staggering 90 percent of all web traffic is local,we are always be told the Inter net has “opened up”the world.As the Chinese curse runs “May you live in interesting times”,it can bring chaos and anxiety in the in the wake.UNIT 55.1dinner at Joanne’sWhen a young black man arrives in a crowded and expensive restaurant,the head waiter makes him sit in the least comfortable place,even though a table has been booked for him and a “Ms Rogers”.When Ms Rogers arrives,the waiter realizes that she is a well-known Senator; and Ms Roger realizes that her friend has been treated badly because of the color of his skin.The waiter realizes his mistake too,and tries to make up for it,but it’s too late.5.2we theyThe writer uses stories about doing business between Swedes and Saudis to illustrate the differences between an individualist and a collectivist approach to business. They have different concepts of the role of personal relationships in business. The Swedes believe the business is donewith a company while the Saudis think it should be done with a person they know and trust.Then the writer compares the characteristics of the collectivist and those of the individualist.In the most collectivist societies,the families are usually extended families while in the individualist societies,nuclear families are prevalent. People consider themselves as part of a “we”group or in-group in the collectivist societies.In contrast, the individualist think of themselves as “I”,their personal identity which is distinct from other people’s. A practical and psychological dependence relationship develops between the person and the in-group in the collectivist societies. However, rarely do people depend on a group in the individualist societies.UNIT 66.1 Last man downThe text from Last Ma Down offers an eyewitness account of defining historical event of 9/11 attack from the perspective of Richard Picciotto, a firefighter; his story is that of a man, a hero,and a tragic event that inspired the nation. His recount isn’t one of death and destruction, but a celebration of life and it’s unpredictable nature.6.2 Eleanor RooseveltThe passage offers a hero who contrasts with brave firefighters. This time she is a woman of power and previlege who still wanted to devote herself to the sucess she believed in.Living in a male-dominated world, Eleanor Roosevelt showed growing concern for women’s issues, along with those for labor issues,youth and civil rights issues.Eleanor created new First Lady profile. She held a press conference for the female only. She was a great supporter for FDR,her wheel-bound husband, whose career as the US president offered her opportunity to come into her own. After FDR’s departure, she still held public posts to use her power to her beliefs.Anna Eleanor Roosevelt never ran on a par with men, she set the place.。

一天深夜我接到要车电话，令我吃惊的是，到达那个地址时发现是一位柔弱的老太太在等我。
她上车后，我便与她攀谈起来。
我了解到她要去安养院，医生说她的时间不多了。
老太太叫我开车穿过市中心。
她指着一些老房子告诉我那是她曾居住或工作过的地方。
最后当车子停在安养院门口时，我没有接收她的车费。
在那天余下的时间里我陷入了沉思：虽然我得谋生，但是生活的意义不仅仅是为了生存。
当周遭情形一片阴暗时，我的一个小小善举可能就是一束烛光，尽管烛火微弱，却温暖了一颗心灵，也令我高尚。
我真的为自己的小小善举感到自豪。
