作业题目:
1、 In this chapter, we show that a time-varying electric field can be produces by a time-varying magnetic field. We will refer to an electric field created by a magnetic field as an induced electric field or an emf-producing electric field. We will also highlight the fact that the induced electric field is not a conservative field. The line integral of an induced electric field around a closed path is, in fact, called the induced emf (electromagnetic force). We will also discover that a time-varying electric field gives rise to a time-varying magnetic field.(翻译为汉语)。
2、 Translate the phrase below into Chinese
(1) Inductive charge;
(2) payload;
(3) dot product
(4) cross product;
(5) transverse electric wave;
(6) unbounded medium;
(7) magnetic field components in the longitudinal direction;
(8) guided waves
(9) microstrip
(10) direction of propagation
3、translate the phrase following into English
(1) 电磁波
(2) 平面波
(3) 传输线
(4) 研制
(5) 自由电子
(6) 半导体
(7) 微波电路
4、英语的词干是一个词的躯体, 是不变化的部分, 体现了该词的基本含义; 词头是词干之前的部分, 它能赋予该词干以新的词义, 派生新词; 词尾是词干之后的部分, 它也能赋予该词干以新的词义, 派生新词。所以, 掌握了常用的词干、词头和词尾, 就能大大地扩展自己的词汇量。下面的英文词语含有duce或 duct词干, 该词干的意义为“引导”,这些具有类似含义的词干成为同源词干。 如果配以不同的词头和词尾, 可以衍生出许多英语单词。
(1)把下列英文词语翻译为汉语;
(2)然后说说词的意思是如何从词干原意派生出来的,并举例说明;
(3)写出你自己认为比较好的一种记忆单词的方法,并说明理由。 conduct
conductor
deduce
induce
inductance
introduce
produce
reduce
reproduce
Productive
