摘    要
加入世貿(mào)組織以后，中國(guó)會(huì)面臨激烈的競(jìng)爭(zhēng)。這種競(jìng)爭(zhēng)將是一場(chǎng)科技實(shí)力、管理水平和人才素質(zhì)的較量，風(fēng)險(xiǎn)和機(jī)遇共存。時(shí)間是最公正的裁判，不管你是富有的還是貧窮的，都會(huì)公平的分配給你大好的時(shí)光，一年三百六十五天，一天二十四小時(shí)，八萬(wàn)六千四百秒，不多不少，就看你如何合理安排了，也許有人會(huì)在一天里創(chuàng)造出一項(xiàng)偉大的發(fā)明或是研究探討出一種新的元素，也許有人會(huì)在一天里碌碌無(wú)為、虛度時(shí)光。那怎樣才能做到珍惜時(shí)間呢？那就要勤勉了，不讓一天閑過(guò)，每時(shí)每刻做些有用的事，戒掉一些不必要的行動(dòng)，這樣你才會(huì)成為時(shí)間的主人，時(shí)間也才會(huì)對(duì)你微笑。于是老師在單片機(jī)理論課程學(xué)習(xí)的基礎(chǔ)上，為我們安排了一個(gè)涉及51單片機(jī)多種資源應(yīng)用及具有綜合功能的電子時(shí)鐘設(shè)計(jì)。希望大家能節(jié)約時(shí)間，合理的安排時(shí)間充分的發(fā)揮它的作用。在這次的設(shè)計(jì)過(guò)程中達(dá)到了因由的效果，也充分的發(fā)揮了知識(shí)的作用。

關(guān)鍵詞：時(shí)間；單片機(jī)；端口；數(shù)碼管

Abstract
After joining the WTO, China will face fierce competition. This competition will be a scientific and technological strength, management quality and talent level of the contest, risks and opportunities coexist. Time is the most impartial referee, whether you are rich or poor, and they will give you a fair distribution of good time, 365 days a year, 24 hours a day, 86400 seconds, not many, many, on how you look reasonable arrangement, and maybe one day someone will be created at a great invention or study a new element, maybe someone will be at day some people may be in the dayYong-Ping mediocre, nothing is as, wasted time. How can we do cherish that time? It should be diligent, and not too busy one day, every moment to do useful things, kick some unnecessary operations, so that you can become the master of time, time will also smile for you. So Teacher CHENHONG courses in SCM theory study on the basis of the arrangements for us to involve a wide range of 51 single-chip applications, and resources with comprehensive function of electron clock design. Hope that we can save time, reasonable arrangements for time to fully play its role. At this time the design process to achieve the effect of the cause, but also sufficient knowledge played a role.

Key Words：time; Single-chip Microcomputer; port; digital tube
