电子信息专业英语(第二版)课件：Laser
Lasers
When real lasers finally arrived—in 1960—writers and moviemakers immediately leaped upon their destructive power and substituted the word “laser” for ray gun. A laser was one of the leading pieces of machinery in the James Bond techno-spy thriller Goldfinger in the early 1960s. As you may recall, Bond (Sean Connery played the role at the time) was tied down to a metal table by the villain Goldfinger, his legs spread apart, while a laser made its way directly toward his genitals. The laser’s bright, red, thick beam easily cut a swath through the table. It obviously had the power to tear him asunder, lengthwise.
Lasers
· Lasers produce light of only one color. Or, to say it in a more technical way, the light is monochromatic. Ordinary light combines all the colors of visible light (i.e., the spectrum). Mixed together, they come out white. Laser beams have been produced in every color of the rainbow (red is the most common laser color), as well as in many kinds of invisible light, but each laser can emit one color and one color only. There are such things as tunable lasers, which can be adjusted to produce several different colors, but even they can emit only one color at a time.[2] A few lasers can emit several monochromatic wavelengths at once—but not a continuous spectrum containing all the colors of visible light as a light bulb does. And then there are many lasers that project invisible light, such as infrared and ultraviolet light.

假如门上加一个正向电压（加在沟道上），于是带负电的电子会吸向该门，这些电子在MOSFET管的沟道区聚集，门上电压越大，在沟道中聚集的电子就越多。
电路上的“0”值的确立是通过另一种连接该电路点和负极电压或接地的晶体管（NMOS）来实现的 。
Current will flow through the NMOS transistor for a very brief interval.
01
But for the NMOS the current is between the circuit and the negative supply.
1、Larry Wissel, ASIC Applications Engineer at IBM Microelectronics, replies:

The transistors are selected by the chip designer from two basic types:
For modem microchips, the transistors are of the kind called metal-oxide-semiconductor field-effect transistor (MOSFET) .
集成电路块中的逻辑门是由特定布局的晶体管组成的。
A MOSFET has three components or regions: a source region, a drain region and a channel region .

电子信息工程专业英语写作范文
电子信息工程专业英语写作范文The field of electronic information engineering has become increasingly crucial in today's rapidly evolving technological landscape. As the demand for advanced digital solutions continues to grow, the importance of effective English writing skills within this discipline cannot be overstated. Proficiency in technical communication is not only essential for academic success but also a valuable asset in the professional realm.One of the key aspects of electronic information engineering is the ability to convey complex technical information in a clear and concise manner. This requires a deep understanding of the subject matter, as well as the ability to translate technical jargon into language that can be easily understood by a diverse audience. Whether it's writing a research paper, a project proposal, or a technical report, the ability to communicate effectively in English is a crucial skill.In the realm of academic writing, electronic information engineering students are often tasked with producing well-researched and well-structured papers that showcase their knowledge and analytical skills. These papers may cover a wide range of topics, from the fundamentals of electronic circuits and systems to the latest advancements in fields such as cybersecurity, artificial intelligence, and the Internet of Things.Effective academic writing in electronic information engineering requires a strong grasp of the technical concepts, as well as the ability to organize and present information in a logical and coherent manner. This may involve the use of various rhetorical strategies, such as problem-solving approaches, comparative analysis, or case studies, to illustrate key points and support the overall argument.Moreover, the ability to effectively communicate research findings and conclusions is essential for success in the academic world. This may involve the presentation of research at conferences, the publication of papers in peer-reviewed journals, or the defense of a thesis or dissertation. In these scenarios, the ability to articulate complex ideas clearly and concisely, while also responding effectively to questions and critiques, is crucial.Beyond the academic realm, the field of electronic information engineering also demands strong English writing skills in the professional context. Engineers in this field may be tasked with writing technical reports, project proposals, or even marketingmaterials to communicate the capabilities and benefits of their products or services to potential clients or stakeholders.Effective professional writing in electronic information engineering requires a deep understanding of the target audience and the ability to tailor the message accordingly. This may involve the use of clear and concise language, the incorporation of relevant data and technical specifications, and the effective use of visual aids, such as diagrams or charts, to enhance the overall communication.Moreover, the ability to write clear and compelling emails, memos, or other forms of professional correspondence is also essential for success in the electronic information engineering field. These forms of communication often serve as the first point of contact between engineers and their clients or colleagues, and the ability to convey information effectively can make a significant impact on the overall success of a project or initiative.In conclusion, the importance of effective English writing skills in the field of electronic information engineering cannot be overstated. Whether it's in the academic or professional context, the ability to communicate technical information clearly and concisely is a crucial skill that can contribute to both individual and organizational success. By developing and honing these skills, students and professionals inthe field of electronic information engineering can position themselves for greater success and advancement in their careers.。

Passage One How do Liquid Crystal Display TVs Work?
• Text • Have you ever seen a snow crystal? Sometimes
it’s possible to see them for a short moment when snow lands on your hand, but most of the time it melts before you get to see the beautiful hexagon-shaped (six-sided) crystals. Crystals are made up of particles that are arranged in a regular pattern and usually come in solid form. For example, when snow melts, it turns into water and loses its crystal shape.
Passage One How do Liquid Crystal Display TVs Work?
• If you put a nail in the middle of two magnets, the edges of the nail will try to point towards each magnet. Similarly, crystals do not have a round shape but have a long narrow shape and when electricity is passed through a crystal, it tries to align itself in the direction of the electrical flow.
• In a liquid crystal TV, many small compartments are left between two pieces of glass. Each of these compartments holds liquid crystals that are colored red, blue or green. Even if light is shined on the back of the screen, the screen remains black because the liquid crystals are not active and block any light from passing through it.

Passage One How do Liquid Crystal Display TVs Work?
• Do you know that there are three states for most objects: solid, liquid and gas? Most things only come in these three forms. However, some material can remain in a state that is somewhat in between a solid and a liquid. In this state, the object is a liquid but still maintains the regular crystal-like arrangement.
