一篇关于it的英语科技文章

Information technology(IT), as defined by the Information Technology

Association of America(ITAA), is “the study, design, development,implementation,

support or management of computer-based information

systems, particularly software applications and computer hardware.” IT deals

with the use of electronic computers and computer software to convert, store,

protect, process, transmit, and securely retrieve , the term

information has ballooned to encompass many aspects of computing and

technology, and the term has become very professionals perform

a variety of duties that range from installing applications to designing complex

computer networks and information databases.A few of the duties that IT

professionals perform may include data management,networking, engineering

computer hardware, database and software design, as well as the management and

administration of entire ation technology is starting to spread

farther than the conventional personal computer and network technology, and

more into integrations of other

technologies such as the use of cell phones, televisions, automobiles, and more,

which is increasing the demand for such computer and communications

technologies are combined, the result is information technology, or “info-

tech”.Information technology is a general term that describes any technology that

helps to produce, manipulate, store, communicate, and/or disseminate information

差速器的历史观后感

作为一个对机械行业不是特别感兴趣的人来说,能让我动心的机械类文章着实不是很

多,当然世间并不缺少美,而是缺少去发现的心境,本是带着练习听力的心情去看这段视

频的,结果却被深深的打动了,不禁为人类的智慧所折服,为机械行业的神奇魅力而倾倒

(虽然学习的兴趣仍然不太浓)。

由于视频是英文的,我看了好几遍才弄清楚意思,原来说的是一种叫做差速器的,在

看这个视频之前,我仅仅听说过差速器这个词,从来不知道是做什么的,总是把他和减速

器混为一谈,然而仔细看完了视频之后发现,差速器的确是人类最伟大的发明之一。

在近一个世纪以来,汽车已经彻底地改变了我们的生活,我们天天可以见到各种型号、

各种品牌的车,但有没有想过,车上有很多地方仔细想想会觉得很别扭,比如车在转弯的

时候就有一个严重的问题,在相同的角速度的前提下,靠近内圈方向的车轮应该转的比外

圈的慢,然而在我的印象中(小时候玩四驱车时),车的两个轮子套在一根轴上,轴随轮

子转动,无论如何是不可能使一个轮在转而另一个轮子不转的。这样两轮共用一个轴并不

意味这不能转弯,而是在转弯的过程中内圈将受到更大的摩擦力,同时会产生轮轴的轴向

力,大大降低零件使用寿命,给行车的安全带来隐患。如果考虑特殊情况,比如其中有一

个轮子滑进了沙坑,就需要让另外一只轮子转动把车戴起来。以上这些问题都引发了科学
