篇一Hello, everyone. It is a great honor for me to be here to express my feelings.
My friends, it is time for us to say goodbye. However, I will never forget the golden days of junior high school. They are forever locked in my memories! In the past three years, I am grateful that I could study with you.
First of all, I’d like to thank all my teachers. It’s you that let me konw how to be a good person. From you, I know that as a good student, we should not only study hard, but also mean well and help each other. Then, I’d like show my appreciation to all my friends. I am grateful that I could study with you. Being together with you, I can totally be myself. I do not need to hide anything from you. When I am sad, you are always on my side to cheer me up.
We will soon become senior high school students. We must go forward, to a different world, we are no
longer the children, who only want to play fun with each other. We grow up from now on! It is a long journey, but let us begin!
你好，每个人。我很荣幸在这里表达自己的感情。
我的朋友们，这是我们说再见的时间。然而，我将永远不会忘记初中黄金时代。他们永远锁在我的记忆中!在过去的三年中，我很感激我能和你们一起学习。
首先，我想感谢我所有的老师。是你们，让我知道如何成为一个好人。从你们那，我知道作为一个好学生，我们不仅应该努力学习，也要互相帮助。然后，我想对我所有的朋友们表示衷心的感谢。我很感激我能和你一起学习。和你在一起，我完全可以做我自己。我不需要你隐瞒任何事情。当我伤心的时候，你总是在我身边使我振作。
我们将很快成为高中生。我们必须前进，在不同的世界里，我们不再是孩子，只想和对方快乐地玩的孩子。我们长大了，从现在开始!这是一个漫长的旅程，但让我们开始吧! 篇二The poet said: spring flowers to the door pushed open a. I said: Thanksgiving to the door pushed open a harmony, harmony open the door to the living. If you carefully listen to the voices of flowers, are everywhere harmonious life movement.
Love, the soul like fire ignited the hope of love,
the soul like propped up the sky. Love is a force, is a wealth. We should be in the hearts of young sow the seeds of love. Let us be thankful for, the Institute of Thanksgiving. Thanksgiving with a heart to face life, in the face of learning, in the face of setbacks, thereby Experience parents, teachers, classmates and friends of selfless relatives and friends, "know drips of TU, when Yongquan of" the real meaning.
Thanksgiving is a traditional virtue of the Chinese nation, build a socialist harmonious society needs. Guangdong lawyer Tian, in order to return the mother's kindness in telling your mother dying when she donated his kidney to restore the mother's life; Xu Yu return to the community of his kindness, decided to leave after graduating from university in the bustling city , broke into the thatched shed to seeking knowledge, a thirst for knowledge sent the children ...
Appreciate your birth, because they allow you access to life; grateful for your dependents, because they allow you to continue to grow; grateful for the concern you, because they give you warmth; grateful to encourage you to the people, because they give you
strength; grateful for your education, because they Kaihua your ignorance; grateful to harm your people because they temper your intellect; grateful for your trip, because it strengthens your legs; grateful for your contempt, because it awakening your self-esteem; grateful abandoned your people, because he taught you that independence; everything grateful, Institute of gratitude, gratitude to all the people you grow up!
Students, and a song called "thank you": I thank the moon lit up the night sky, thanks to the dawn Zhaoxia endorse for the spring snow melt for the land feeding the people, to thank his mother for giving me life ... thank harvest for peace for all of this all all.
Thanksgiving-Fighting, Thanksgiving unlimited! Students, and Society Thanksgiving! Let us always to the life caring and full of love and love! Let us brought up their hands and work together, everyone aspired to build a socialist harmonious society!
诗人说：花朵把春天的门推开了。我说：感恩把和谐的门推开了，和谐把生活的门推开了。只要你用心去听花开的声音，生活到处都是和谐的乐章。
爱，像火种点燃心灵的希望; 爱，像绿茵撑起心灵的天
空。爱，是一种力量，是一种财富。我们应该从小在心中撒播爱的种子。让我们心存感激，学会感恩。用一颗感恩的心去面对生活，面对学习，面对挫折，从而体会父母，师长，同学，朋友间无私的亲情，友情，"懂得滴水之恩，当涌泉相报”的真正内涵.
感恩是中华民族的传统美德，是构建社会主义和谐社会的需要。广东律师田世国为了回报母亲的恩情，在老母病危时瞒着她捐出了自己的肾脏，挽回了母亲的生命;徐本禹为了回报社会对他的恩情，毅然在大学毕业后离开繁华城市，走进穷乡僻壤的破草棚，给求知若渴的孩子们送去知识……
感激生育你的人，因为他们使你获得生命;感激抚养你的人，因为他们使你不断成长;感激关怀你的人，因为他们给你温暖;感激鼓励你的人，因为他们给你力量;感激教育你的人，因为他们开化你的蒙昧;感激伤害你的人，因为他们磨练了你的心智;感激绊倒你的人，因为它强化了你的双腿;感激藐视你的人，因为它觉醒了你的自尊;感激遗弃你的人，因为他教会了你该独立;凡事感激，学会感激，感激一切使你成长的人!
同学们，有首歌叫《感谢你》：感谢明月照亮了夜空，感谢朝霞捧出的黎明，感谢春光融化了冰雪，感谢大地哺育了生灵，感谢母亲赐予我生命……感谢收获、感谢和平、感谢这所有的一切一切。感恩无痕，感恩无限!同学们，学会
感恩吧!让我们的生活永远走向关怀，充满真情和爱心!让我们携起来手来，共同努力，构建一个人人向往的社会主义和谐社会!
篇三各位敬爱老师，同学们：大家好!今天，我站在这里，代表全体初三毕业生向我们的母校道别，向×三中的老师们道别，向朝夕相处的同窗们道别，也向这段不能忘怀的岁月道别!让我们真诚的向老师们说一声：谢谢
my dear teachers and classmates ,good evening !today i stand here to stand for all our graduates to say good bye to our beloved school ,to this unforgettable memory and to our dear teachers and classmates .and this is the time to say thank you to all my teachers .
三年的学习时光，弹指一挥间，但很多事情值得我们珍惜，明亮的教室，高大的树木和美丽的鲜花。
how time flies ,it has been 3 years since we entered the school .but there are so many things is worth to cherishing ,such as the bright classroom ,tall trees and beautiful flowers .
这三年的路，我们走的辛苦而快乐，三年的生活，我们过的充实而美丽，我们流过眼泪，却伴着欢笑，我们踏着荆棘，却嗅得万里花香。we spent these 3 years with hardship
and happiness ,fully and meaningful ,sorrow and happy and during this time we learned a lot . 现在，我们不仅学会了语文、数学，而且学会了物理和化学，不仅提笔能写文章，最重要的一点在于，使我更清楚地知道爱的含义，这是老师们心血的结晶。up to now ,we not only learned Chinese , maths,physics ,chemistry, but also learned how to write articles etc .
above all ,it makes me know what is is the result of our teachers' hardworking .虽然我们离开了母校，但学习的脚步不会停下，我们还会接受更好的教育。even though we will left our mother school ,we will never give up receiving advanced education .take it easy ,my dear teachers !i won't let you in the future
篇四My dear Mr. and Misses, my fellows schoolmates,Good morning! As you know and see, it is a sunny bump harvest season. In the city, in our school campus, everywhere is surrounded with roses which we together planted 4 years ago. Today may these roses and our friendship as well be together and comfort our excited hearts!It was four years ago that everyone of us came from every part of China and formed a new collective. As we are young, it’s very easy for us to
communicate. It was in the past four years that we were ambitious. It was in the past four years that we worried. It was in the past four years that we were content. It was in the past four years that we were vexed. It was in the past four years that we were friendly and lonely ... and it was in the past fours that we studied, lived and respected each other with genuine and with our ambitions. Nothing in the world is more significant than we miss all of miss you─teachers who are tireless in teaching; we will keep your gestures and your white hairs in our hearts deeply; we will miss the quietness with the lights at night in the classroom; we will miss the race and exercise on the playground; we will miss even the crowds in the dining hall and the quarrel on the beds; we will still miss every green piece and every piece of waste paper flying like flakes in the air ... However, today we will leave nothing but the first rose with our Alma Mater and our teachers which is entrusted with our love and years seems very long but 4 years seems very short. From now on, we all will go into the society. The society is broad and wide for us. We will shoulder heavy responsibilities; we
will work diligently; and we will expect to be informed of good news from one another. Now, I beg you all to cherish the occasion; to remember the names, the status, appearance and the character of the person around you. Now let’s be hand in hand together; let’s present the rose to each other. May the rose carry our appreciation and blessing! We are very closely linked no matter what the world may be. May the fresh rose in our hands keep its fragrants!Thank you all again!学友们：大家都瞧见了，这是一个阳光灿烂的收获季节。在这座城市，在我们的校园，到处都是玫瑰朵朵，这是4年前我们共同栽培的。今天，就让鲜花和友情聚拢，安抚我们激动不已的心吧! 4年前，大家从天南海北来到这里，组成了一个新的集体。年轻的心是最容易相通的，尽管4年中有追求有失落，有得意有烦恼，有欢乐有忧虑，有友爱有孤寂......但我们都曾怀着真诚而美好的初衷去学习、生活、相爱，没有什么比这些更有意义，更令我们怀念。我们怀念每一位诲人不倦的老师，你们的手势或白发会刻在我们的记忆中;怀念教室里的静夜苦读，运动场上的奔跑跳跃，甚至食堂里的拥挤和高低床上的争论; 怀念每一块绿地和每一片风中飘零的废纸......今天，我们没有更好的礼物留下，这第一朵玫瑰，就献给我们的母校和老师，她寄托着大家的热爱和敬意!
4年很久，4年也很匆匆。以后的日子，大家又要飞，天高地阔，任重道远，我们将在躬身的劳作中和奉献中等候着彼此的好消息。现在，请珍惜和永远记住这一时刻，记住你左边和右边的任何一个人吧，记住他(她)们的姓名、仪表和特点，请让我们彼此握手，彼此赠佩一朵玫瑰，让她表达我们的感谢和祝福。不管地老天荒，我们彼此息息相关，我们的手指上永远保留着赠人鲜花的芳香! 谢谢大家!

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 growing 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, something significant. Now what we

江苏科技大学 2010年 03 月 28 日 均布荷载作用下挡土墙上的土压力 G. I. Shvetsov UDC 624.131.531.2 在前一篇文章中，我们确定了在只考虑填土自重的试验条件下，作用在挡土墙上的压力。这篇文章是第一篇文章的延续，致力于探索填土在外界均布荷载作用下，在挡土墙上产生的荷载问题，当在使用到先前得到的岩土平衡微分方程时，我们仅仅只改变边界条件，因为在这种情况下我们使用了与初始解决方案相同的原理。我们只提取那些与附加土压力有关的新成果，以及仅定义那些第一次出现的新符号。 在设计中，我们通常把作用在挡土墙上的土压力看作是呈三角形分布的，应力也被假设为是沿着墙体均匀连续分布的，但是实验结果并没有证实这一理论，试验表明表面
的附加应力随墙的高度变化并不均匀，而是从回填土顶部的最大值开始一直减小到其底部的最小值。因而，在M.C.瓦尔跟实验图的纵坐标的最大值超出理论计算值近两倍，最小值达到理论计算值的0.65倍，因为土压力的增加主要是在墙的上部，由此所得出的作用点比计算所得出的要高很多。 F.M.shikhiev 的理论里包含了关于挡土墙均布荷载作用下的二维应力折减问题，但是， 附加应力的分布对挡土墙受超荷载作用的效果问题的影响，并没有经过合适的理论研究。 虽然，不同研究人员所做的无数次试验已经确定，侧壁的扭曲效应更大，随着表面的粗糙程度而变大，随挡土墙的宽度和高度之比。在这篇文章里，我们将尽可能的填补这方面的空白。 在边界条件0q 0,y x ==的基础上，我们可以确定试验中作用在有侧向限制的填土上没有超荷的垂直应力。如果一个外附加应力作用在楔块表面上的强度为x σ，则在这种情况下，我们可以从已知条件得出，当y=0时，x q = x σ，既可以得出方程 ()()1 1 1/2/k x x w w h y h A q f m h A λσξ+-=+ （1） 其中 ，荷载分配的不均匀系数A 1和土的深度有关： ()() 111/1/k k A y h y h -= --- （2） 方程一是通用的，因为对于任意一种荷载分布x σ它都可以计算出任意土层中某一点的应力，因此便足以表明应力在X 轴方向的分布规律。当0=x σ时，方程便简化成相应的没有附加应力的形式，并且，当0=w f 而且0>x σ时，它反映了在考虑了附加应力条件时的二维问题，即： 11k x x h y q A h γσ?? =+- ??? （3） 满布在滑动楔上的均布荷载对我们已经知道的设计系数k ，n,和ξw 的值并没有影响，所以，计算作用在挡土墙上的正应力，切应力和总应力的表达式如下：
We Are The World ,We Are The Future Someone said “we are reading the first verse of the first chapter of a book, whose pages are infinite”. I don’t know who wrote these words, but I’ve always liked them as a reminder that the future can be anything we want it to be. We are all in the position of the farmers. If we plant a good seed ,we reap a good harvest. If we plant nothing at all, we harvest nothing at all. We are young. “How to spend the youth?”It is a meaningful question. To answer it, first I have to ask “what do you understand by the word youth?”Youth is not a time of life, it’s a state of mind. It’s not a matter of rosy cheeks, red lips or supple knees. It’s the matter of the will. It’s the freshness of the deep spring of life. A poet said “To see a world in a grain of sand, and a heaven in a wild flower, hold infinity in the palm of your hand, and eternity in an hour. Several days ago, I had a chance to listen to a lecture. I learnt a lot there. I’d like to share it with all of you. Let’s show our right palms. We can see three lines that show how our love.career and life is. I have a short line of life. What about yours? I wondered whether we could see our future in this way. Well, let’s make a fist. Where is our future? Where is our love, career, and life? Tell me.Yeah, it is in our hands. It is held in ourselves. We all want the future to be better than the past. But the future can go better itself. Don’t cry because it is over, smile because it happened. From the past, we’ve learnt that the life is tough, but we are tougher. We’ve learnt that
使用高级分析法的钢框架创新设计 1．导言 在美国，钢结构设计方法包括允许应力设计法(ASD)，塑性设计法(PD)和荷载阻力系数设计法(LRFD)。在允许应力设计中，应力计算基于一阶弹性分析，而几何非线性影响则隐含在细部设计方程中。在塑性设计中，结构分析中使用的是一阶塑性铰分析。塑性设计使整个结构体系的弹性力重新分配。尽管几何非线性和逐步高产效应并不在塑性设计之中，但它们近似细部设计方程。在荷载和阻力系数设计中，含放大系数的一阶弹性分析或单纯的二阶弹性分析被用于几何非线性分析，而梁柱的极限强度隐藏在互动设计方程。所有三个设计方法需要独立进行检查，包括系数K计算。在下面，对荷载抗力系数设计法的特点进行了简要介绍。 结构系统内的内力及稳定性和它的构件是相关的，但目前美国钢结构协会（AISC）的荷载抗力系数规范把这种分开来处理的。在目前的实际应用中，结构体系和它构件的相互影响反映在有效长度这一因素上。这一点在社会科学研究技术备忘录第五录摘录中有描述。 尽管结构最大内力和构件最大内力是相互依存的（但不一定共存），应当承认，严格考虑这种相互依存关系，很多结构是不实际的。与此同时，众所周知当遇到复杂框架设计中试图在柱设计时自动弥补整个结构的不稳定（例如通过调整柱的有效长度）是很困难的。因此，社会科学研究委员会建议在实际设计中，这两方面应单独考虑单独构件的稳定性和结构的基础及结构整体稳定性。图28.1就是这种方法的间接分析和设计方法。
在目前的美国钢结构协会荷载抗力系数规范中，分析结构体系的方法是一阶弹性分析或二阶弹性分析。在使用一阶弹性分析时，考虑到二阶效果，一阶力矩都是由B1,B2系数放大。在规范中，所有细部都是从结构体系中独立出来，他们通过细部内力曲线和规范给出的那些隐含二阶效应，非弹性，残余应力和挠度的相互作用设计的。理论解答和实验性数据的拟合曲线得到了柱曲线和梁曲线，同时Kanchanalai发现的所谓“精确”塑性区解决方案的拟合曲线确定了梁柱相互作用方程。 为了证明单个细部内力对整个结构体系的影响，使用了有效长度系数，如图28.2所示。有效长度方法为框架结构提供了一个良好的设计。然而，有效长度方法的

大学毕业论文英文翻译 中文译文 计算机网络 每个一个世纪都有一种主导地位的技术。18世纪伴随着工业革命的到来的是大型机械系统的时代；19世纪是蒸汽机的时代，而20世纪的发展历程中，关键的技术是信息收集、处理和分发。在其他的发展方面，我们还可以看到：遍布全球的电话网络的建立起来了，无线电广播和电视的出现了，计算机工业诞生了，并且以超乎想象的速度在成长；另外通信卫星也发射上天了。 技术的快速发展的一个直接结果是，这些领域正在快速地融合，信息收集、传输、存储和处理之间的差别正在迅速地消失。对于具有数百个办公室的大型组织来说，尽管这些办公室分布在广阔的地理区域中，但未来期望的情景是，工作人员只要单击一下按钮，就可以查看最远处分部的状态。随着信息收集、处理和分发能力的不断提高，我们对于更加复杂的信息处理技术的需求也增长得更快。 与其他的工业(比如汽车和航空运输业)相比，计算机工业还是非常年轻，尽管如此，计算机技术却在很短的时间内有了惊人的进展。在计算机诞生之初的20年间，计算机系统是高度集中化的，通常位于一个很大的房间中。该房间通常配有玻璃墙，参观的人透过玻璃墙可以欣赏到里边伟大的电子奇迹。中等规模的公司或者大学可能会有一台或者两台计算机，而大型的研究机构最多也就几十台计算机。要在20年内生产出大量同样功能但是体积比邮票还小的计算机，在当时的人们看来纯属科学幻想。 计算机和通信的结合对于计算机系统的组织方式产生了深远的影响。把一台大型的计算机放在一个单独的房间中，然后用户带着他们的处理任务去房间里上机，这种"计算机中心"的概念现在已经完全过时了。由一台计算机来处理整个组织中所有的计算需求，这种老式的模型已经被新的模型所取代，在新的模型下，由大量独立的，但相互连接起来的计算机来共同完成计算任务。这些系统称为计算机网络(computer networks)。如何设计这些网络，并且将这些网络组织起来，这就是本书的主题。 在本书中，我们将使用术语"计算机网络"来表示通过同一种技术相互连接起来的一组自主计算机的集合。如果两台计算机能够交换信息，则称

1. Introduction America is one of the countries that speak English. Because of the special North American culture, developing history and the social environment, American English has formed its certain unique forms and the meaning. Then it turned into American English that has the special features of the United States. American English which sometimes also called United English or U.S English is the form of the English language that used widely in the United States .As the rapid development of American economy, and its steady position and strong power in the world, American English has become more and more widely used. As in 2005, more than two-thirds of English native speakers use various forms of American English. The philologists of the United States had divided the English of the United States into four major types: “America n creating”; “Old words given the new meaning”; “Words that eliminated by English”;“The phonetic foreign phrases and the languages that are not from the English immigrates”[1]. Compared to the other languages, American English is much simple on word spelling, usage and grammar, and it is one of the reasons that American English is so popular in the world. The thesis analyzes the differences between American English and British English. With the main part, it deals with the development of American English, its peculiarities compared to that of British English, its causes and tendency. 2. Analyses the Differences As we English learners, when we learning English in our junior or senior school, we already came across some words that have different spellings, different pronunciations or different expressions, which can be represented by following contrasted words: spellings in "color" vs. "colour"; pronunciations in "sec-re-ta-ry" vs. "sec-re-try";
My Chinese Dream(我的中国梦) I am very glad to stand here to give thier a short speech.Today my topic is that the youth are the future of motherland(我很荣幸站在这里做这篇短 小的演讲，我演讲的主题是青年是祖国的未来。) When preparing for the English speech contest, I simply want to search some articles as the contents of my speech. I read a lot of articles, some from the university professor, some from the famous host, some from the college students, and even from junior high school students. But after reading it, I gave up the idea, I even felt shameful. Today,the topic I want to talk about is a solemn and serious theme full of glory and pride, which is a common aspiration of all our Chinese. Every Chinese has his own dream of China, and of course, there is a dream lingering in my heart only belongs to my own.(在准备英语演讲比赛的时候，我本想简单地从网上搜索一些 文章作为我演讲的内容。我看过很多文章，有著名主持人的、北大教授的、大学生的，也有初中生的。但是看完之后，我放弃了当初的想法，我甚至为当初的想法感到有一些羞愧。因为今天我站在这里向大家演讲的主题，是一个庄重而严肃的主题；是一个充满荣耀与自豪的主题；是每一个中华儿女共同期盼的主题。每个人都有属于他们自己的中国梦，而我，当然也有一直萦绕在心怀只属于我的中国梦。) So what’s my Chinese dream ? Finall y I will announce. We had learned a lot of knowledge and understood a lot of truth in the book. We had a basic concept to our country at that time. We know that our country is full of sunshine , and we are the future of our country, and our dreams are to be the hope of our motherland.我的中国梦是什么样的？先卖 个关子。记得刚刚上学那会儿，我们天真无邪。在课本里，我们学到了很多很多知识，也明白了很多很多道理，我们对祖国也有了一个最基本的概念。我们知道我们的祖国到处充满阳光，正在慢慢发展，而我们，就是祖国未来的花朵，未来的希望。我们梦想将来能够
英语演讲稿1分半励志带翻译 英语演讲稿随着时代的发展，演讲技能已经变成一种基本技能。同时，演讲的艺术性也越来越受重视。关于英语演讲稿1分半励志带翻译的有哪些呢?下面是xx为你整理的内容，希望对你有帮助。 篇一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 together. 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 growing 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
Advantages of Managed Code Microsoft intermediate language shares with Java byte code the idea that it is a low-level language witha simple syntax , which can be very quickly translated intonative machine code. Having this well-defined universal syntax for code has significant advantages. Platform independence First, it means that the same file containing byte code instructions can be placed on any platform; atruntime the final stage of compilation can then be easily accomplished so that the code will run on thatparticular platform. In other words, by compiling to IL we obtain platform independence for .NET, inmuch the same way as compiling to Java byte code gives Java platform independence. Performance improvement IL is actually a bit more ambitious than Java bytecode. IL is always Just-In-Time compiled (known as JIT), whereas Java byte code was ofteninterpreted. One of the disadvantages of Java was that, on execution, the process of translating from Javabyte code to native executable resulted in a loss of performance. Instead of compiling the entire application in one go (which could lead to a slow start-up time), the JITcompiler simply compiles each portion of code as it is called (just-in-time). When code has been compiled.once, the resultant native executable is stored until the application exits, so that it does not need to berecompiled the next time that portion of code is run. Microsoft argues that this process is more efficientthan compiling the entire application code at the start, because of the likelihood that large portions of anyapplication code will not actually be executed in any given run. Using the JIT compiler, such code willnever be compiled.

附件1：外文资料翻译译文 基于一维CFD模型下汽车排气消声器的实验研究与预测Takeshi Yasuda, Chaoqun Wua, Noritoshi Nakagawa, Kazuteru Nagamura 摘要目前，利用实验和数值分析法对商用汽车消声器在宽开口喉部加速状态下的排气噪声进行了研究。在加热工况下发动机转速从1000转/分钟加速到6000转/分钟需要30秒。假定其排气消声器的瞬时声学特性符合一维计算流体力学模型。为了验证模拟仿真的结果，我们在符合日本工业标准（JIS D 1616）的消声室内测量了排气消声器的瞬态声学特性，结果发现在二阶发动机转速频率下仿真结果和实验结果非常吻合。但在发动机高阶转速下（从5000到6000转每分钟的四阶转速，从4200到6000转每分钟的六阶转速这样的高转速范围内），计算结果和实验结果出现了较大差异。根据结果分析，差异的产生是由于在模拟仿真中忽略了流动噪声的影响。为了满足市场需求，研究者在一维计算流体力学模型的基础上提出了一个具有可靠准确度的简化模型，相对标准化模型而言该模型能节省超过90％的执行时间。 关键字消声器排气噪声优化设计瞬态声学性能 1 引言 汽车排气消声器广泛用于减小汽车发动机及汽车其他主要部位产生的噪声。一般而言，消声器的设计应该满足以下两个条件：（1）能够衰减高频噪声，这是消声器的最基本要求。排气消声器应该有特定的消声频率范围，尤其是低频率范围，因为我们都知道大部分的噪声被限制在发动机的转动频率和它的前几阶范围内。（2）最小背压，背压代表施加在发动机排气消声器上额外的静压力。最小背压应该保持在最低限度内，因为大的背压会降低容积效率和提高耗油量。对消声器而言，这两个重要的设计要求往往是互相冲突的。对于给定的消声器，利用实验的方法，根据距离尾管500毫米且与尾管轴向成45°处声压等级相近的排气噪声来评估其噪声衰减性能，利用压力传感器可以很容易地检测背压。 近几十年来，在预测排气噪声方面广泛应用的方法有：传递矩阵法、有限元法、边界元法和计算流体力学法。其中最常用的方法是传递矩阵法（也叫四端网络法）。该方
