Computer Mouse
鼠标
The basic computer mouse is an amazingly clever invention with a relatively simple design that allows us to point at things on the computer and it is very productive.
鼠标是一个非常神奇,非常聪慧的发明,简单的设计使我们可以点击电脑上的任意东西,并且很具有市场潜力。
Think of all the things you can do with a mouse like selecting text for copying and pasting1,drawing,and even scrolling on the page with the newer mice with the wheel.
你可以使用鼠标选择文本,进行复制粘贴,绘画,甚至使用新鼠标的滚轮可以实现页面的切换。
Most of us use the computer mouse daily without stopping to think2 how it works until it gets dirty and we have to learn how to clean it.
每天我们都在不停的使用鼠标,但是从不去考虑它是如何工作的,直到它被用脏以后,我们才不得不考虑如何清洗它。
We learn to point at things before we learn to speak, so the mouse is a very natural pointing device.
我们都是先学会指认某个事物,然后才学会用语言表达,所以鼠标就自然应运而生了。
Other computer pointing devices include light pens, graphics tablets and touch screens。but the mouse is still our workhorse.
其他的电脑点击输入设备包括:光信号笔,绘图板以及触摸屏。但是鼠标依然是我们的主要工作工具。
The computer mouse was invented in l964 by Douglas Englehart of Stanford University
鼠标是在1964年由斯坦福大学的道格拉斯-英格哈特发明的。
As computer screens became more popular and arrow keys were used to move around a body of text, it became clear that a pointing device that allowed easier motion through the text and even selection of text would he very useful.
当显示器越来越流行并且箭头式的光标被广泛应用时,显然,一个能够在文本之间更灵活的移动并能够实现文本的选择的点击设备的出现将会非常有用。
The introduction of the mouse, with the Apple Lisa computer in l983, really started the computer public on the road to relying on the mouse for routine computer tasks.
随着苹果电脑在1983年推出的新机型——Lisa ,鼠标开始真正加入到公众的计算机的日常工作当中。
How does the mouse work? We have to start at the bottom, so think upside down tor now. It all starts with the mouse ball.
鼠标是如何工作的呢?我们先从底部开始研究,现在将它翻转,关键就在鼠标球上。
As the mouse ball in the bottom of the mouse rolls over the mouse Dad, it presses against and turns two shafts.
当鼠标底部的鼠标球开始旋转的时候,有两个轴将会受到挤压并发生旋转。
The shafts are connected to wheels with several small holes in them.
这些轴与内部的一些滚轮(不是中间的大滚轮)相连,每个滚轮上都有许多小孔。
The wheels have a pair of small electronic light-emitting devices called light—emitting diodes (LED) mounted on either side
滚轮的另一侧悬置有一对电子发光装置,叫做发光二极管。
One LED sends a light beam to the LED on the other side. As the wheels spin and a hole rotates by, the light beam gets through to the LED on the other side.
在带有小孔的滚轮旋转的同时,一只发光二极管发出光束,穿过小孔,打到另一只二极管上。
But a moment later the light beam is blocked until the next hole is in place.
随着滚轮的旋转,光束的线路受阻,直到下一个小孔转到光束的位置上,光才可以继续通过。
The LED detects a changing pattern of light, converts the pattern into an electronic signal, and sends the signal to the computer through wires in a cable that goes out the mouse body.
发光二极管可以探测到光束变化的模式,并将光信号转变成电信号,再通过鼠标线传递到计算机当中。
This cable is the tail that helps give the mouse its name. The computer interprets the signal to tell it where to position the cursor on the computer screen.
鼠标线就像鼠标的尾巴。计算机将传来的信号进行“翻译”并告诉屏幕上的光标,它应该在什么位置。
So far we have only discussed the basic computer mouse that most of you probably have or have used.
目前我们只是讨论了最基本的我们最有可能应用到的鼠标。
One problem with this design is that the mouse gets dirty as the ball rolls over the surface and picks up dirt. Eventually you have to clean your mouse
有一个问题,就是如果鼠标脏了,鼠标球表面有污垢,会影响它正常工作,最终我们还是要对他进行清理。
The newer optical mice avoid this problem by having no moving parts.
更先进的光电鼠标由于没有移动部件,可以避免这个问题。
这是一个好文章!就是内容有点落伍!

电脑鼠标
基本电脑鼠标是一个令人惊讶的聪明,发明了一个比较简单的设计,使我们能够点东西,在电脑上,这是非常富有成果。认为所有的东西,你可以做一个鼠标一样,选择的文字复制并pasting1 ,绘画,甚至滚动在网页上与较新的小鼠与车轮。我们大多数人使用电脑滑鼠每日不停车,以think2如何运作,直到获得肮脏,我们要了解如何进行清洁。我们学会点东西之前,我们学习发言,所以鼠标是一个很自然的指向装置。其他电脑指针设备,包括光笔,图形片和触摸屏,但鼠标仍然是我们的Workhorse机型。
计算机鼠标发明在l964由道格拉斯恩格尔哈特的斯坦福大学。作为电脑屏幕上,成为更受欢迎和箭头键被用来走动,一正文,人们清楚地看到指向装置,使更容易通过的议案文本,甚至选择文本,他将非常有用。推出的鼠标,与苹果电脑丽莎在l983 ,真正启动计算机,市民对道路,依靠对小鼠进行例行电脑tasks.3
请问鼠标的工作呢?我们已开始在底部,所以觉得倒Tor的现在。这一切开始与鼠标球。随着鼠标在大厅的底部,鼠标翻转鼠标爸爸,它塑机反对,轮流二轴。该轴连接到车轮与几个小孔,在他们的。车轮有一个对小型电子有机电致发光器件所谓的发光二极体( LED )的安装在任何side4 。一个LED发出的光束,以发光二极管的另一面。由于车轮自旋和一个洞,旋转,光束获得通过,以发光二极管的另一面。但稍后光束被封锁,直至下一个洞是在地方。发光二极管侦测到的变化规律轻,转换模式转化为电子信号,并将信号传输到计算机,通过在一个电线电缆熄灭鼠标机构。这是有线电视的尾巴,有助于让鼠标其名称。计算机解释的信号,告诉它在何处光标定位在计算机屏幕上。
直至目前为止,我们只讨论了基本的计算机鼠标,大部分的您可能已经或有used.5一个问题,这个设计是鼠标得到肮脏当球翻转表面和拿起污物。最终,你必须清洁您的鼠标。较新的光学鼠标避免这个问题,因没有任何运动机件。
