Lecture 11
No network of DC lines is possible at this time because no circuit breaker is available for direct current comparable to the highly developed AC breakers. The AC breaker can extinguish the arc which is formed when the breaker opens because zero current occurs twice in each cycle. The direction and amount of power in the DC line is controlled by the converters in which grid-controlled mercury-arc devices are being displaced by the semiconductor devices. 1. Unlike overhead lines, underground cable is invisible, free from atmospheric pollution, and solves the problem of securing rights of way. 和架空线不同,地下电缆是看不见的,免受大气污染,并解 决了安全的公用通道问题。

Hale Waihona Puke Lecture 112. DC transmission remains very limited in usage except for long lines because there is no DC device which can provide the excellent switching operations and protection of the AC circuit devices. 直流输电除用于长线(输电)以外在应用上仍然十分有限, 这是因为没有直流设备能够提供交流装置所具有的卓越的开 关操作和保护功能。 3.

1.1 什么是专业英语
例 1 : If a mouse is installed in a computer, then the available memory space for user will reduce. 错误译法:如果让老鼠在计算机里面筑窝,那么使用者的记忆空 间就会减少。 专业译法:如果计算机安装了鼠标,则用户可利用内存空间就会 减少。
例2:Connect the black pigtail with the dog- house. 错误译法:把黑色的猪尾巴系在狗窝上。 专业译法:将黑色的引出线接在(高频高压电源)屏罩上。
1.1 什么是专业英语
1. 专业英语与普通英语
(2) 外文科技文章在结构上也具有很多自身的特点,如长句多, 被动语态多,大量的名词化结构等,这都给对原文的理解 和翻译带来了基础英语中很难解决的困难。 例: The heating system and the water heater(热水器) in a house are system in which only the sign of the difference between desired and actual temperatures is used for control.
The mechanical energy can be changed back into electrical through a generator 发电机可以把机械能再转换成电能
1.2 学习专业英语的重要性
(1) 科研信息获取
专业英语阅读能力 当前大部分资料都可以通过互联网传播,而这些资料中 90 %以上都 是英语。 世界上科技情报资料的交流主要靠使用英语 ,对于自动化相关专业来 说,绝大部分专业资料和信息都是以英语形式出观。
是结合各自专业的科技英语 有很强的专业性,涉及的面 更加狭窄,与专业内容配合更为密切。
专业英语与科技英语既有区别又有联系。专业英语的学 习需要有一个良好的科技英语基础,同时也要注意其自 身的词汇特点、语法特点、修辞特点和翻译特点等等。
2. 科技英语与专业英语

If the Earth's rotation was not slowing, there would be none of this stress, and its shape would have remained constant throughout the ages
Work must be done in setting a body in motion. 使一个物体运动时,必须做功(词义引申)。 Boiling point is defined as the temperature at which the vapor pressure is equal to that of the atmosphere. 沸点的定义就是气压等于大气压时的温度。(v → n)
