个人电脑发展到现在,鼠标已经成了标准配置之一,功能也越来越强大。例如按键的数量从一个两个发展到现在的四个五个甚至更多,其中最具有代表性的,就是滚轮的出现,部分鼠标(例如双飞燕4D等)还有两个甚至更多的滚轮。这些滚轮极大地方便了使用者,给他们日常使用鼠标带来很大便利。有些朋友可能有过类似的疑问:为什么用手指拨动滚轮,窗口中的内容就会随之滚动呢?要回答这个问题,最好的办法就是拆开鼠标,看看这个滚轮是如何工作的。
Up to now, the mouse has become one of the standard configuration, the function is also more and more powerful. For example, the number of buttons has increased from one to two, four to five or more. The most representative ones are the appearance of wheels, some mice (such as Shuangfeiyan 4D, etc.) and two or more wheels . These rollers greatly facilitate the user, giving them great convenience to use the mouse daily. Some friends may have had similar questions: Why do you use the fingers to move the wheel, the contents of the window will scroll with it? To answer this question, the best way is to open the mouse to see how this wheel works.
