A business survives and thrives on information: information within the organization and information changed with suppliers, customers,and regulators. Moreover, the information needs to be consistent, accessible, and at the right location. We consider information in four forms-voice, data, image, and video-and the implications of distributed requirements.The term voice communications refers primarily to telephone related communications. By far the most common form of communication in any organization and for most personnel is direct telephone conversation. The telephone has been a basic tool of business for decades. Telephone communications has recently been enhanced by a variety of computer-based services, including voice mail and computerized telephone exchange systems. V oice mail provides the ability to send, forward , and reply to voice messages nonsimultaneously , and it has become a cost-efficient tool even for many midsize organizations. It provides saving on answering machines and services as well as more responsive service to customers and suppliers. Advances have also been made in computerized telephone exchange systems, including in-house digital private branch exchanges(PBX) and Centrex systems provided by the local telephone company. These new systems provide a host of features, including call forwarding, call waiting, least-cost routing of long-distance calls, and a variety of accounting and auditing features.The term data communications is sometimes used to refer to virtually any form of information transfer other than voice. It is sometimes convenient to limit this term to information in the form of text(such as reports, memos, and other documents) and numerical data(such as accounting files). The rapid changes in technology have created fresh challenges for management in making effective use of data communications. We will briefly outline the changes in technology in transmission, networks, and communications software that present the manager with new powerful business tools but also the necessity of making choices among complex alternatives.一个企业生存和蓬勃发展的信息：在改变与供应商，客户和监管机构的组织和信息的信息。

Each mode has most of the energy inside the core, but due to the evanescent fields outside the core, a part of the energy is also traveling in the cladding. By making the cladding sufficiently thick, the fields of the mode at the cladding-air boundary can be made small, thus making it easy to handle and support without causing much disturbance to the modes.

第1章 信息与通信工程专业英语(第2版)_韩定定
联想意义是人们在概括 自己对客观世界的感性 认识和情感体验之后， 通过联系、类比等手段 赋予词汇一定的象征意 义。联想意义是词汇内 涵的重要组成部分，同 样植根于文化的土壤之 中。
英汉颜色词，从物理学角度讲是没有 区别的，但在语言交流中，它们却各 具不同的联想意义，成为象征色彩。 例如，黄色(yellow)在中国文化中象征 至高无上的权力或色情淫秽，人们常 说“黄袍加身”、“黄色书刊” 等， 但在美国，yellow没有这种特定的内涵， 人们常用蓝色(blue)来指代色情(如a blue movie)。再如，绿色(green)在汉 语中象征春天、新生的希望，但一提 到它，英美人却会由此想到嫉妒(green eyed)与缺乏经验(green hand)。
关于英汉习俗差异，最 典型的莫过于在对狗这 种动物的态度上。
狗在汉语中是一种卑微的动物。 “狐朋狗党”、“狗急跳墙”、 “狼心狗肺”、“狗腿子”等。 西方英语国家，狗被认为是人类 最忠诚的朋友。 You are a lucky dog 你是一个幸运儿 Every dog has his day 凡人皆有得意日 Old dog will not learn new tricks 老人学不了新东西 as sick as a dog 病得厉害
总之，文化差异现象 的根源主要由于概念 意义的差异和联想意 义的差异。
概念意义是客观事物在 人们意识中的反映和概 括。在中西方不同文化 背景下，客观事物本身 存在差异，因此，英汉 词汇在概念意义上常具 有不同的内涵。
西方饮食中的sandwich、 hamburger、salad，中国人既未看 过，也未吃过，只好音译为“三明 治”、“汉堡包”、“色拉”，美 国人生活中特有的drugstore，汉 语中还没有一个词语能贴切地表达 其内涵，也只能以注释性的文字说 明它是“出售药物、糖果、饮料及 其他日用杂品的店铺”。同样，汉 语里的一些词，如“天干”、“地 支”、“楷书”、“普通话”、 “太极拳”等，在英语中也找不到 对应词。
通信工程专业英语教程
通信工程专业英语教程The field of communication engineering has experienced remarkable advancements in recent years, driven by the rapid technological progress and the ever-increasing demand for efficient and reliable communication systems. As the world becomes more interconnected, the role of communication engineers in shaping the future of global communication networks has become increasingly crucial. To meet the evolving needs of this dynamic industry, the development of a comprehensive and well-structured English curriculum for communication engineering majors is of paramount importance.The primary objective of an English curriculum for communication engineering students should be to equip them with the necessary language skills and technical knowledge to effectively navigate the global landscape of communication technologies. This curriculum should be designed to not only enhance their proficiency in English but also to provide them with a deep understanding of the specialized terminology, concepts, and methodologies relevant to their field of study.One of the core components of such a curriculum should be a strong emphasis on technical writing and communication. Communication engineers are often required to prepare technical reports, proposals, and presentations, which necessitate the ability to convey complex information in a clear, concise, and professional manner. The English curriculum should therefore include courses that focus on technical writing, report writing, and professional communication, providing students with the opportunity to develop these essential skills.In addition to technical writing, the curriculum should also incorporate language training that caters to the specific needs of communication engineers. This may include courses on academic English, scientific and engineering English, as well as English for specific purposes (ESP) courses that cover topics such as telecommunication systems, signal processing, and network protocols. By providing students with a solid foundation in the language used in their field, they will be better equipped to engage in discussions, read and comprehend technical literature, and collaborate with international colleagues.Another crucial aspect of the English curriculum for communication engineering majors should be the integration of project-based learning. This approach allows students to apply their language and technical skills in real-world scenarios, fostering their ability to work in teams, solve complex problems, and communicate effectively withdiverse stakeholders. Such projects may involve the design and implementation of communication systems, the analysis of network performance, or the development of innovative communication technologies.Furthermore, the curriculum should incorporate opportunities for students to engage in international collaborations and exchanges. This could include student exchange programs, virtual international team projects, or participation in global communication engineering conferences and workshops. These experiences not only enhance students' language proficiency but also expose them to different cultural perspectives and industry practices, preparing them for the global nature of the communication engineering field.To ensure the effectiveness of the English curriculum, it is essential to incorporate ongoing assessment and feedback mechanisms. This may include regular evaluations of students' language proficiency, technical knowledge, and communication skills, as well as feedback from industry partners and alumni to ensure the curriculum remains relevant and responsive to the evolving needs of the communication engineering sector.In conclusion, the development of a comprehensive English curriculum for communication engineering majors is a crucial step in preparing the next generation of communication professionals. Bycombining language instruction with technical knowledge and practical application, this curriculum will equip students with the necessary skills and competencies to thrive in the dynamic and globally interconnected world of communication engineering. As the demand for efficient and innovative communication systems continues to grow, the importance of a well-designed English curriculum cannot be overstated, as it will contribute to the development of highly skilled and globally-minded communication engineers who can drive the future of the industry.。
