商务英语函电的翻译技巧

1 引言

随着国际贸易市场竞争的日益激烈,国际间的贸易来往更加频繁,而商务英语就成了国际间来往的桥梁,它也是国际贸易活动中不可缺少的沟通工具。实际上,商务英语控制着国际交流,国际交流离不开商务英语,这也必然导致商务信函风格和语言上变化,曾经那些千篇一律的陈旧词汇已经无法跟上新时代的发展了。而今,商务交流中的信息来往要求内容简单,重点突出,并已经成为一种交流趋势,而商务英语函电的翻译要从商务信函的文体语言特点着手。

2 商务英语函电的特点

商务函电与一般的交流信息不同,它特点鲜明,并有固定的翻译原则,其目的是维持良好的业务关系,促进商务沟通,保证正常的商务来往。其核心为效率,经济性与简洁性为效率的核心,并要求高效率和充实的内容,二者是互相促进的,缺一不可。

2.1 文体特点

在信息重新分配和组合的过程中,要首先考虑语言的结构,尤其是文体。事实上,文体主要分为5类,即专业文体、正式文体、非正式文体、随意文体、亲密文体。由于商务函电直接涉及到国家之间的贸易来往信息,且同银行、海关、运输、法律等专业知识有着密不可分的联系,所以应今本归纳为专业文体或者正式文体。

2.2 语言特点

商务函电所要求的三个基本原则是:准确、简洁、清楚。这些都是对语言方面的要求,而体贴、礼貌,则是针对态度和角度方面的要求。同时要求格式的完整,函电内容也要具体丰富,内容中要避免一些无实际意义的多余词汇,内容要严格的把握重点。商务函电不仅有特殊的背景,还要求翻译人员要有实际的商务工作技能。

主要的语言特点可以归纳为两点:商务函电的涉及范围有贸易、金融、外汇、海关、商检等诸多领域,其行业特征比较明显,因此,需要对语言进行合理选择;商务人员的思

维模式具体、审慎,讲究语言表达的分寸。具体的表现是,语言表达要简单明了,突出重点。用词规范、语法结构严谨、句子排列一般固定有序。语篇连贯、逻辑性强。

2.3 翻译特点

商务函电翻译的目的是要体现函电的实际效用,能准确及时的传达信息,而绝非是为了单纯的美感和语言的华丽。按照贸易的不同类型,其翻译目的也不一样,采用不同的手段处理不同的内容;翻译过程是固定的,严格控制错误。因而,翻译人员不仅要熟悉专业知识,还要有合理的发挥。

翻译的根本在意表达准确的意思,还要求专业术语的精确;同时,要善于运用语言,用有限的词汇表达出更精准的意思,将相关的信息更为精练准确地表达出来。由于商务函电涉及英、汉语言的翻译与运用,且函电又有其语言、语法、句子结构等方面的特殊性,再加上中西文化上的差异,这也导致了商务函电的翻译可能无法精确的表达其意思,只能是相对的精确。因此,我们必须认识到这一点,对今后商务函电的翻译起着重要的作用。

3 商务英语函电的翻译技巧

正确的理解原文的意思是做好翻译工作的基础。翻译是对两种语言的转换,需要翻译人员对两种语言都有较好的理解,并合理解决它们之间存在的差异。而娴熟的翻译技巧就是处理这里问题的方法,翻译技巧所涉及的内容十分广泛,从语言到语法,从结构到内容,每一个方面都需要翻译技巧作为翻译基础,可见,翻译技巧在函电翻译中起着十分重要的作用。

3.1 词汇翻译技巧

商务英语函电的词汇翻译很关键,而对专业词汇的精确运用则体现出娴熟的翻译技巧,其中包含一些大学专业词汇,具有商务含义的普通词和复合词,以及一些专业的缩写词等。例如UC表示信用证;W.P.A水演险等等。如果翻译人员对这些专业词汇不了解或者没有专业知识,就无法做好商务函电的翻译。

英语和汉语中,相同的词汇会出现不同意思和不同范围的的情况,这些都属于一词多意,如果仅仅依靠查字典,是无法真正解决问题的,必须在联系上下文的意思后,通过总结,找出该词汇代表的真实含义。在商务英语函电中,我们还会遇到一些词在其实际应

用中与其它词语搭配后产生具体意义。

商务函电翻译与一般的文学翻译不同。文学翻译要保证原文的神韵和内容,做到神似。函电翻译需要的是对内容的精准翻译。

首先,要按照语言使用规范正确的使用套语。如:Please quote us the lowest price CIF New York with a 5 percent commission,and indicate the quantity that you can supply for October shipment.利用套语就应该是“请报来最低CIF纽约价包括5%佣金,并说明可供十月份装运的数量。”其次,要注意多义词的使用。如“The product will find a good market in New York”。此产品在纽约将有很好的销路。“Chinese ceramic products are verypopular in Europe.We would like to work with you to market themin Canada”。中国的陶瓷产品在欧洲很受欢迎,我们愿同你方合作在加拿大销售。”

从上面两个例子中可以看出,market既有市场、销路,又有营销、出售之意。翻译时还要根据上下文的意思,对该词做正确的翻译,避免误解。如The goods were received contrary to our instructions arepacked in wooden cases without iron hoops。句中的contrary to our instructions实际上是修饰“包装”而不是“货物”的意思。正是因为由contrary to our instructions的位置提前,容易让翻译人员误解。

最后,在遵守翻译程序时,还要注意翻译技巧的运用。如信函中Dear sirs,一般不译为“亲爱的先生们”,而译为“(执事)先生”或“径启者”。

3.2 用词礼貌,语气委婉

一份文雅、彬彬有礼有质量的函电,会让阅读信件的人心情舒畅,同时留下良好的印象,对双方的贸易来往有积极的作用,这对这笔交易的达成有很大的促进作用。所以,译员在翻译外贸信函时要选择合适的语言,不仅要实现正确的翻译,还要将原文中要表达的礼貌充分的体现出来,保证翻译能在语言上形成对等。我们主要可以通过使用正确的语气,恰当的委婉语以及适度的模糊语策略来实现。

例如,当拒绝对方的报盘时,通常使用“We regret to say that…”等较为温和语气来表达自己的意思。即使本次交易没有成功,也会给对方留下好的印象,不会影响到未来的合作关系。“We are afraid, we would say…”“Wouldyou like…”等句型也都有舒缓语气、避免绝对化的作用,可以给业务合作留下更多商量和协作的余地,有利于合作关系的建立。翻译时适当使用模糊用语可以使礼貌策略更加突出。

3.3 译文流畅,风格一致

在外贸活动中,交易双方从陌生到熟悉,从建立业务关系开始直到交易的达成,期间交往的信函不计其数,随着不断变化的状况,信函的内容也千变万化。然而信函翻译的风格应该保持整体的一致连贯,如实反映信函的原貌,让阅读信函的人有亲切的感觉,不致觉得唐突陌生。英文函电翻译的这些专业化特点要求翻译人员必须投入大量的时间和精力不断丰富完善自身的专业知识与翻译技巧,从而适应对外贸易迅猛发展的需要。

4 结语

综上所述,商务函电是现在国际商务间交流的方式之一。由于它属于特殊文体,其语言的专业性有着特殊的要求,要求译者从词义和专业上,在结合上下文的意思,去完整的翻译全文,保证译文所传达的信息与原文所传递的信息一致。翻译内容需要等值这个理论,在很大程度上促进了函电的准确翻译,严格控制了译文和原文在意义上的差异,在商务函电翻译中的应用有助于强化译文的逻辑性、规范性和准确度。正确运用动态等值理论,在商务函电翻译中具有重要意义。

Business English translation skills

1 INTRODUCTION

As international trade increasingly fierce market competition, international trade from more frequent, and business English has become a bridge between the international community, it is indispensable to international trade communication tools. In fact, business English in control of international communication, international communication is inseparable from business English, business correspondence is also bound to lead to changes in style and language, which fits the old words have been unable to keep up with the development of a new era. Today, the exchange of information between business requirements is simple, focused, and has become a communication trend, Business English translation of

2 Characteristics of Business English

Business correspondence and exchange of information in general is different from its distinct characteristics and a fixed translation principle, its objective is to maintain good business relations, the promotion of business communication, to ensure normal business dealings. The core efficiency, economy, efficiency and simplicity to the core, and for high efficiency and substantial content, the two are mutually reinforcing, and indispensable.

2.1 Style of the body

Re-allocation and portfolio in the information process, we should first consider the structure of language, especially in style. In fact, the style is divided into five categories, namely professional style, formal style, informal style, free style, intimate style. As the business correspondence directly related to trade between countries of information, and with banks, customs, transportation, and legal expertise are inextricably linked, it should be divided into

professional sports today, or the official style.

2.2 Language Features

Business correspondence required by the three basic principles: accurate, concise and clear. These are the language requirements, and considerate, polite, it is for the attitude and perspective requirements. Form also asked the integrity of the concrete correspondence should be rich in content, content to avoid redundant without meaningful words, content to take a strict focus. Business correspondence is not only special background, also called translators have real business skills.

The main language features can be summarized in two points: the scope of Business Correspondence concerning trade, finance, foreign exchange, customs, commodity inspection, and many other areas, more obvious features of its industry, therefore, need to be a reasonable choice of language; the specific mode of thinking of business people carefully, pay attention to language and when not. Specific performance is that language should be simple and clear, focused. Standardized terminology, grammar, well-structured, arranged in the general fixed sentence order.

Coherence, logic and strong.

2.3 Translation features

Business correspondence translation is intended to reflect the actual effect of correspondence, accurate and timely communication of information, rather than to pure beauty and beautiful language. According to different types of trade, the purpose of their translation are not the same, using different means to handle different content; translation process is fixed, strict control of the error. Thus, the translator must not only familiar with the professional knowledge, but

also a reasonable play.

Translation not care about the meaning of the expression of accurate, precise terminology is also required; the same time, necessary to use the language with limited vocabulary to express a more precise meaning, the relevant information is more concise and accurate expression. As the business correspondence related to the English and Chinese language translation and application, and correspondence has its language, grammar, sentence structure and other aspects of the specialty, plus Cultural differences, which led to the translation of business correspondence may not be accurate the expression of its meaning, can only be relatively accurate. Therefore, we must recognize this, the translation of business correspondence in the future play an important

role.

3 Business English translation skills

Correct understanding of original meaning is the basis for doing translation work. Translation is the conversion of two languages, two languages to be translated officers have a better understanding of, and reasonable solution to the differences between them. The consummate translation skills to the problem here is dealing with translation skills involved are very broad, from language to grammar, from structure to content, every aspect of the translation needs of translation skills as the basis, can be seen in the correspondence translation translation

3.1 Vocabulary Translation

Vocabulary Business English translation is critical, while the precise use of vocabulary is demonstrated skilful translation skills, including some universities specialized vocabulary, the meaning of common words with the business and compound words, and so professional abbreviations.

UC says such letters of credit; W.P.A water play, etc. insurance. If the translators did not understand these terms or no professional expertise,

English and Chinese, the same words appear in different means and different areas of the case, these are all multi-word meaning, if the dictionary alone is not really solving the problem, you must contact the context of the mean and, by summing up to find out the true meaning of the words represent. In Business English, we will encounter some words in their practical application in other words with concrete meaning

Business correspondence translation and literary translation in general different. Literary translation to ensure the original charm and content, so that bore a striking resemblance. Correspondence translation is

First of all, according to the correct use of language to use standard sets of words.Such as:Please quote us the lowest price CIF New York with a 5 percent commission, and indicate the quantity that you can supply for October shipment. Using sets of words should be "Please quote CIF New York, the lowest price, including 5% commission, and indicate the amount available for shipment in October." Second, we must pay attention Polysemy use. Such as "The product will find a good market in New York". This product will be in New York has a good market. "Chinese ceramic products are verypopular in Europe.We would like to work with you to market themin Canada". China's ceramic products are very popular in

From the above two examples can be seen, market both markets, sales, another marketing, sale was intended. Translation, but also based on the context, do the right translation of the word, to avoid misunderstanding. If The goods were received contrary to our instructions arepacked in

wooden cases without iron hoops. Sentence, contrary to our instructions are actually modified the "packaging" rather than "goods" means. Because contrary to our instructions from the position in advance, easy to

Finally, in compliance with translation program, but also pay attention to the use of translation skills. If the letter Dear sirs, are generally not translated as "Dear Sir", but translated as "(Deacon) Mr." or "Path

3.2 words polite, tactful tone

A polite, courteous and quality, correspondence, make people feel comfortable reading the letter, while a good impression on the trade between the two sides have a positive effect, which reached the deal will greatly promote effect. Therefore, the translator in the translation of foreign correspondence should select the appropriate language of the time, not only to achieve a correct translation, but also to convey the original text of the full manifestation of courtesy, to ensure the formation of translation in the language of the other. We mainly by using the right tone, appropriate euphemism, as well as appropriate strategies

For example, when refused to offer each other, usually using the "We regret to say that ..." and other more moderate tone to express his meaning. Even if the transaction is not successful, will give each other a good impression and will not affect future cooperation. "We are afraid, we would say ..." "Wouldyou like ..." and other sentences also have a soothing tone, to avoid the absolute role can be to discuss business cooperation and collaboration to leave more room for the establishment of beneficial cooperation . Appropriate use of vague language

3.3 Mr smooth, consistent style

In foreign trade activities, transactions both from strange to familiar, from the beginning until the establishment of business relations reached a deal, during numerous exchanges of correspondence with the changing conditions, contents of the letter is also changing. However, the translation correspondence should maintain a consistent style, consistent, accurately reflects the original letter, so read the letters people have kind of feeling, not that strange abruptness. English translation of the specialized features of correspondence required translators to be putting in a lot of time and energy to constantly enrich and improve their professional knowledge translation skills to suit the

4 Conclusion

In summary, business correspondence is now an international business exchange between one of the ways. Because it is a special style, their language has a special professional requirements, requirements and professional translator from the meaning, in the meaning in context, to complete the translation of text, to ensure translation of information conveyed by the message with the original line . Translation content requires the equivalent of this theory to a large extent contributed to the accurate translation of correspondence, strict control of the translation and the original in the sense of the differences in translation of business correspondence translation help to reinforce the logic of normative and accuracy. Correct use of dynamic equivalence theory, translation of business correspondence of great significance.

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

Section 3 Design philosophy, design method and earth pressures 3.1 Design philosophy 3.1.1 General The design of earth retaining structures requires consideration of the interaction between the ground and the structure. It requires the performance of two sets of calculations: 1)a set of equilibrium calculations to determine the overall proportions and the geometry of the structure necessary to achieve equilibrium under the relevant earth pressures and forces; 2)structural design calculations to determine the size and properties of thestructural sections necessary to resist the bending moments and shear forces determined from the equilibrium calculations. Both sets of calculations are carried out for specific design situations (see 3.2.2) in accordance with the principles of limit state design. The selected design situations should be sufficiently Severe and varied so as to encompass all reasonable conditions which can be foreseen during the period of construction and the life of the retaining wall. 3.1.2 Limit state design This code of practice adopts the philosophy of limit state design. This philosophy does not impose upon the designer any special requirements as to the manner in which the safety and stability of the retaining wall may be achieved, whether by overall factors of safety, or partial factors of safety, or by other measures. Limit states (see 1.3.13) are classified into: a) ultimate limit states (see 3.1.3); b) serviceability limit states (see 3.1.4). Typical ultimate limit states are depicted in figure 3. Rupture states which are reached before collapse occurs are, for simplicity, also classified and

摘要:编程节点和活跃网络的概念将可编程性引入到通信网络中,并且代码和数据可以在发送过程中进行修改。最近,多个研究小组已经设计和实现了自己的设计平台。每个设计都有其自己的优点和缺点,但是在不同平台之间都存在着互操作性问题。因此,我们引入一个类似网络socket编程的概念。我们建立一组针对应用程序进行编程的简单接口,这组被称为活跃网络Socket编程(ANSP)的接口,将在所有执行环境下工作。因此,ANSP 提供一个类似于“一次性编写,无限制运行”的开放编程模型,它可以工作在所有的可执行环境下。它解决了活跃网络中的异构性,当应用程序需要访问异构网络内的所有地区,在临界点部署特殊服务或监视整个网络的性能时显得相当重要。我们的方案是在现有的环境中,所有应用程序可以很容易地安装上一个薄薄的透明层而不是引入一个新的平台。 关键词:活跃网络;应用程序编程接口;活跃网络socket编程

1 导言 1990年,为了在互联网上引入新的网络协议,克拉克和藤农豪斯[1]提出了一种新的设 计框架。自公布这一标志性文件,活跃网络设计框架[2,3,10]已经慢慢在20世纪90 年代末成形。活跃网络允许程序代码和数据可以同时在互联网上提供积极的网络范式,此外,他们可以在传送到目的地的过程中得到执行和修改。ABone作为一个全球性的骨干网络,开 始进行活跃网络实验。除执行平台的不成熟,商业上活跃网络在互联网上的部署也成为主要障碍。例如,一个供应商可能不乐意让网络路由器运行一些可能影响其预期路由性能的未知程序,。因此,作为替代提出了允许活跃网络在互联网上运作的概念,如欧洲研究课题组提出的应用层活跃网络(ALAN)项目[4]。 在ALAN项目中,活跃服务器系统位于网络的不同地址,并且这些应用程序都可以运行在活跃系统的网络应用层上。另一个潜在的方法是网络服务提供商提供更优质的活跃网络服务类。这个服务类应该提供最优质的服务质量(QOS),并允许路由器对计算机的访问。通过这种方法,网络服务提供商可以创建一个新的收入来源。 对活跃网络的研究已取得稳步进展。由于活跃网络在互联网上推出了可编程性,相应 地应建立供应用程序工作的可执行平台。这些操作系统平台执行环境(EES),其中一些已 被创建,例如,活跃信号协议(ASP)[12]和活跃网络传输系统(ANTS)[11]。因此,不 同的应用程序可以实现对活跃网络概念的测试。 在这些EES 环境下,已经开展了一系列验证活跃网络概念的实验,例如,移动网络[5],网页代理[6],多播路由器[7]。活跃网络引进了很多在网络上兼有灵活性和可扩展性的方案。几个研究小组已经提出了各种可通过路由器进行网络计算的可执行环境。他们的成果和现有基础设施的潜在好处正在被评估[8,9]。不幸的是,他们很少关心互操作性问题,活跃网络由多个执行环境组成,例如,在ABone 中存在三个EES,专为一个EES编写的应用程序不能在其他平台上运行。这就出现了一种资源划分为不同运行环境的问题。此外,总是有一些关键的网络应用需要跨环境运行,如信息收集和关键点部署监测网络的服务。 在本文中,被称为活跃网络Socket编程(ANSP)的框架模型,可以在所有EES下运行。它提供了以下主要目标: ??通过单一编程接口编写应用程序。 由于ANSP提供的编程接口,使得EES的设计与ANSP 独立。这使得未来执行环境的发展和提高更加透明。

The Injection Molding The Introduction of Molds The mold is at the core of a plastic manufacturing process because its cavity gives a part its shape. This makes the mold at least as critical-and many cases more so-for the quality of the end product as, for example, the plasticiting unit or other components of the processing equipment. Mold Material Depending on the processing parameters for the various processing methods as well as the length of the production run, the number of finished products to be produced, molds for plastics processing must satisfy a great variety of requirements. It is therefore not surprising that molds can be made from a very broad spectrum of materials, including-from a technical standpoint-such exotic materials as paper matched and plaster. However, because most processes require high pressures, often combined with high temperatures, metals still represent by far the most important material group, with steel being the predominant metal. It is interesting in this regard that, in many cases, the selection of the mold material is not only a question of material properties and an optimum price-to-performance ratio but also that the methods used to produce the mold, and thus the entire design, can be influenced. A typical example can be seen in the choice between cast metal molds, with their very different cooling systems, compared to machined molds. In addition, the production technique can also have an effect; for instance, it is often reported that, for the sake of simplicity, a prototype mold is frequently machined from solid stock with the aid of the latest technology such as computer-aided (CAD) and computer-integrated manufacturing (CIM). In contrast to the previously used methods based on the use of patterns, the use of CAD and CAM often represents the more economical solution today, not only because this production capability is available pin-house but also because with any other technique an order would have to be placed with an outside supplier. Overall, although high-grade materials are often used, as a rule standard materials are used in mold making. New, state-of-the art (high-performance) materials, such as ceramics, for instance, are almost completely absent. This may be related to the fact that their desirable characteristics, such as constant properties up to very high temperatures, are not required on molds, whereas their negative characteristics, e. g. low tensile strength and poor thermal conductivity, have a clearly related to ceramics, such as sintered material, is found in mild making only to a limited degree. This refers less to the modern materials and components

MATERIALS AND MANUFACTURING PROCESSES, 17(3), 401–413 (2002) POLISHING OF CERAMIC TILES C. Y. Wang,* X. Wei, and H. Yuan Institute of Manufacturing Technology, Guangdong University ofTechnology, Guangzhou 510090, P.R. China ABSTRACT Grinding and polishing are important steps in the production of decorative vitreous ceramic tiles. Different combinations of finishing wheels and polishing wheels are tested to optimize their selection. The results show that the surface glossiness depends not only on the surface quality before machining, but also on the characteristics of the ceramic tiles as well as the performance of grinding and polishing wheels. The performance of the polishing wheel is the key for a good final surface quality. The surface glossiness after finishing must be above 208 in order to get higher polishing quality because finishing will limit the maximum surface glossiness by polishing. The optimized combination of grinding and polishing wheels for all the steps will achieve shorter machining times and better surface quality. No obvious relationships are found between the hardness of ceramic tiles and surface quality or the wear of grinding wheels; therefore, the hardness of the ceramic tile cannot be used for evaluating its machinability. Key Words: Ceramic tiles; Grinding wheel; Polishing wheel

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

,the National Institute of Standards and Technology (NIST) has been working to develop a new encryption standard to keep government information secure .The organization is in the final stages of an open process of selecting one or more algorithms ,or data-scrambling formulas ,for the new Advanced Encryption Standard (AES) and plans to make adecision by late summer or early fall .The standard is slated to go into effect next year . AES is intended to be a stronger ,more efficient successor to Triple Data Encryption Standard (3DES),which replaced the aging DES ,which was cracked in less than three days in July 1998. “Until we have the AES ,3DES will still offer protection for years to come .So there is no need to immediately switch over ,”says Edward Roback , acting chief of the computer security division at NIST and chairman of the AES selection committee .“What AES will offer is a more efficient algorithm .It will be a federal standard ,but it will be widely implemented in the IT community .” According to Roback ,efficiency of the proposed algorithms is measured by how fast they can encrypt and decrypt information ,how fast they can present an encryption key and how much information they can encrypt . The AES review committee is also looking at how much space the algorithm takes up on a chip and how much memory it requires .Roback says the selection of a more efficient AES will also result in cost savings and better use of resources . “DES w as designed for hardware implementations ,and we are now living in a world of much more efficient software ,and we have learned an awful lot about the design of algorithms ,”says Roback .“When you start multiplying this with the billions of implementations done daily ,the saving on overhead on the networks will be enormous .” ……
