电子信息工程专业英语Unit 1 Electronic DevicesLesson 1 VLSI Technology •Backgrounds•Text tour•Language in use–Vocabulary–Structure–Reading/writing techniques Backgrounds•Terminology–Transistor vs. vacuum tube–Conductivity & semiconductor–Miniaturization , IC, LSI, VLSI•Timeline of Electronic Technology Evolution•Company Information–Bell Laboratories–Texas Instruments–Intel CorporationTerminologyTransistor vs. vacuum tubeThe vacuum tube is an electron tube from which all or most of the gas has been removed, permitting electrons to move with no or low interaction with any remaining gas molecules.真空管是一种内部气体全部或部分抽空的电子管，从而使电子在不受或少受气体分子的干扰下运动。

• A transistor is a device that conducts a variable amount of electricity through it, depending on how much electricity is input to it. In other words, it is a digital switch.However, unlike the vacuum tube , it is solid state .•晶体管是一种依据输入电量大小而传导可变电量的器件。

Unit 6Telecommunication TechnologyChapter Three&Part4 Extensive Reading @Part 1 Notes to Text@Part5Notes to Passage & Part 2 Word Study@Part3 Practice on Text @Part6 Practice on PassageChapter Study Tasks （3）In this chapter, you will be able to—Identify the key concepts of telecommunication—Learn the basics of data and serial communications—Get the general ideas of the text and the extensive reading—Complete all the practice required@Part 1 Notes to TextKey Concepts of Telecommunication1) In modern times, this process typically involves thesending of electromagnetic waves by electronictransmitters, but in earlier years it may have involvedthe use of smoke signals, drums or semaphore. 在现代，这种传递的典型方式就是使用电子发射器发送电子波。

而在较早的年代，传递方式可能用的是烟火讯号、击鼓声和旗语通讯法注释：注意this process指代的是前文说的信号传递方式；第二分句中的主语it依然是指信号传递方式。
