Text and notes


Developments in computer technology and related
software have provided the engineer with tools of
increasing power and sophistication which have significant
implications for the use and role of mathematics in
engineering practice.
计算机技术及其相关软件的发展为工程技术人员提供了功能
强大且日趋完善的工具，使数学应用于工程实践并发挥着重
要作用。

Text and notes


If engineers are to take full advantage of sophisticated
computational tools then it is essential that they become
effective at mathematical modelling and discriminating,
intelligent and wary users of packaged software and
other aids to computational modelling.
如想充分利用这些复杂的计算工具，工程技术人员必须熟
悉数学模型，能区别各种软件包及其他计算机建模辅助工
具，并能灵活运用。

Text and notes


There is little doubt that a high degree of fluency in the
manipulation of mathematical expressions will always be
required, for without this there can be no real
understanding.
毫无疑问，学生必须熟练运用数学公式，否则就不可能有
真正意义上的理解。

Text and notes


Consequently, this book is not a collection of recipes and
techniques designed to teach students to solve routine
exercises, nor is mathematical rigor introduced for its
own sake.
因此，本书既不是教授学生解题方法与技巧的汇总，也未
以数学本身所要求的严谨方式编写。
上海海事大学信息工程学院
Text and notes


As a result of the widening of access opportunities,
particularly in the United Kingdom, there is increasing
heterogeneity in background knowledge in mathematics
of students entering degree courses in engineering.
由于入学机会增多，修读工程类学位课程学生的数学基础
愈见参差不齐，尤以英国为甚。

Grammar－科技英语的语法特点

科技英语作为一种揭示客观外部世界的本质和规
律的信息传递工具，具有准确(exact)、简明扼要
(concise)和客观(objective)正式(formal)等特点。

科技英语文体的特点：语言简练、结构严谨、逻
辑性强、原理概念清楚、重点突出、段落章节分
明。
上海海事大学信息工程学院
词汇(words and expressions)
大量的专业词汇和半专业词汇：
Special words: calculus, bandwidth, flip-flop;
Semi-special words: series(级数，串联)
 大量使用词缀和词根：
Tele, poly (polytechnic), auto etc
 较多使用缩略词：
PCM (pulse-coded modulation), CDMA (code
division multiple access), DSP (digital signal
processing)
 词性变换多：
Sound: n(声音), v(听起来), adj(合理的，健全的)

上海海事大学信息工程学院
语法(grammar)


常用一般现在时态，表示真理或客观规律的陈述。
Vector and matrix technique provide the framework for
much of the developments in modern engineering.
广泛使用被动语态，强调所论述的客观事物。
Chapters 7 and 8 are devoted to the calculus of
functions of one variable and, recognizing again the
mixed background knowledge in mathematics of the
students, the basic ideas and techniques of
differentiation and integration are reviewed in Chapter 7.
上海海事大学信息工程学院
语法(grammar)
普遍使用名词词组及名词化结构，强调客观存在
的事实而非某一行为，故常使用表示动作或状态
的抽象名词。
Television is the transmission and reception of
images of moving objects by radio waves.
 使用非限定动词，使句子简明。
The calculus, aided by analytic geometry,
proved to be astonishingly powerful and capable
of attacking hosts of problems that had been
baffling and quite unassailable in earlier days.

上海海事大学信息工程学院
句法(syntax)





较常使用“无生命主语＋及物动词＋宾语”句型
Chapter 6 provides a basic introduction to the
ideas of sequences, series and limits.
常用it做形式主语或形式宾语。
It has been proved that induced voltage causes
a current to flow in opposite to the force
producing it.
The invention of radio has made it possible for
mankind to communicate with each other over a
long distance.
上海海事大学信息工程学院
句法(syntax)




尽量用紧缩型状语从句而不用完整句。
While designed primarily for use by engineering
students, it is believed that the book is also
highly suitable for students of the physical
sciences and applied mathematics.
割裂修饰比较普遍
It is hoped that this provision, together with the
large number of worked examples and style of
presentation, also makes the book suitable for
private or directed study.
上海海事大学信息工程学院
句法(syntax)




较多使用祈使语气
Let the forward-pass transfer function be given by the
linear difference equation.
句中并列成分较多
Radar has certain inherent advantages over detection
systems employing light waves:(1)it has greater
range,(2)it is usable in any weather and in day or night,
and (3) the electronic circuitry and components for
transmitting, receiving, amplifying, detecting and
measuring are highly developed.
上海海事大学信息工程学院
句法(syntax)


复杂长句多。科学技术要阐述事物之间错综复杂的关系，
因而需要用复杂的语法关系来表达严密复杂的思维。长句
所表达的科技内容严密性、准确性和逻辑性较强。
Recognizing the increasing use of numerical methods in
engineering practice, which often complement the use of
analytical methods in analysis and design and are of
ultimate relevance when solving complex engineering
problems, there is wide agreement that they should be
integrated within the mathematics curriculum.
