Want, want, line is clear, as if nothing could shake his. Also once seemed to be determined to do something, but more often is he backed out at last. Dislike his cowardice, finally found that there are a lot of love, there are a lot of miss, like shadow really have been doomed. Those who do, just green years oneself give oneself an arm injection, or is a selfrighteous spiritual.　　一個(gè)人的時(shí)候，自己的想法總是特別地清晰。想要的，不想要的，界限明確，好像沒(méi)有什么可以撼動(dòng)自己。也曾經(jīng)好像已經(jīng)下定了決心去做某件事，但更多的時(shí)候是最后又打起了退堂鼓。嫌惡過(guò)自己的怯懦，最終卻發(fā)現(xiàn)有很多緣分，有很多錯(cuò)過(guò)，好像冥冥之中真的已經(jīng)注定。那些曾經(jīng)所謂的非做不可，只是青蔥年華里自己給自己注射的一支強(qiáng)心劑，或者說(shuō)，是自以為是的精神寄托罷了。At the moment, the sky is dark, the air is fresh factor after just rained. Suddenly thought of blue plaid shirt。 Those were broken into various shapes of stationery。 From the corner at the beginning of deep friendship。 Have declared the end of the encounter that haven39。t start planning... Those years, those days of do, finally, like youth, will end in our life.　　此刻，天空是陰暗的，空氣里有著剛下過(guò)雨之后的清新因子。突然想到那件藍(lán)格子襯衫；那些被折成各種各樣形狀的信紙；那段從街角深巷伊始的友誼；還有那場(chǎng)還沒(méi)有開(kāi)始就宣告了終結(jié)的邂逅計(jì)劃……那些年那些天的非做不可，終于和青春一樣，都將在我們的人生中謝幕。Baumgartner the disappointing news: Mission aborted. r plays an important role in this mission. Starting at the ground, conditions have to be very calm winds less than 2 mph, with no precipitation or humidity and limited cloud cover. The balloon, with capsule attached, will move through the lower level of the atmosphere (the troposphere) where our daytoday weather lives. It will climb higher than the tip of Mount Everest ( miles/ kilometers), drifting even higher than the cruising altitude of mercial airliners ( miles/ kilometers) and into the stratosphere. As he crosses the boundary layer (called the tropopause),e can expect a lot of turbulence.The supersonic descent could happen as early as Sunda.The weatheThe balloon will slowly drift to the edge of space at 120,000 feet ( Then, I would assume, he will slowly step out onto something resembling an Olympic diving platform.Below, the Earth bees the concrete bottom of a swimming pool that he wants to land on, but not too hard. Still, he39。ll be traveling fast, so despite the distance, it will not be like diving into the deep end of a pool. It will be like he is diving into the shallow end. Skydiver preps for the big jumpWhen he jumps, he is expected to reach the speed of sound 690 mph (1,110 kph) in less than 40 seconds. Like hitting the top of the water, he will begin to slow as he approaches the more dense air closer to Earth. But this will not be enough to stop him pletely.If he goes too fast or spins out of control, he has a stabilization parachute that can be deployed to slow him down. His team hopes it39。s not needed. Instead, he plans to deploy his 270squarefoot (25squaremeter) main chute at an altitude of around 5,000 feet (1,524 meters).In order to deploy this chute successfully, he will have to slow to 172 mph (277 kph). He will have a reserve parachute that will open automatically if he loses consciousness at mach speeds.Even if everything goes as planned, it won39。t. Baumgartner still will free fall at a speed that would cause you and me to pass out, and no parachute is guaranteed to work higher than 25,000 feet (7,620 meters).cause there8 致謝這次單片級(jí)的課程設(shè)計(jì)讓我受益匪淺，首先我要感謝電氣工程學(xué)院的副教授朱衛(wèi)華老師和助教吳榮燕老師給予的熱情的指導(dǎo)和幫助，在他們的指導(dǎo)下我們找到了解決課程設(shè)計(jì)困難的途徑，他們?yōu)槲揖臏?zhǔn)備了一系列的設(shè)計(jì)題目并幫我們解答了課程設(shè)計(jì)的格式以及要求等很多問(wèn)題，也提供了多種獲得課程設(shè)計(jì)參考資料的途徑以及方法。更重要的是在我們做實(shí)物時(shí)給予了莫大的幫助，更是從中學(xué)到了許多書(shū)本上沒(méi)有的知識(shí)，加強(qiáng)了自己個(gè)方面的能力，尤其是在動(dòng)手能力方面更為明顯，看到自己辛辛苦苦做出來(lái)的電路板，所說(shuō)有點(diǎn)累但別提有多高興，最重要是從中體會(huì)到了學(xué)習(xí)的快樂(lè)。從此樹(shù)立了自己學(xué)習(xí)以及奮進(jìn)的目標(biāo)。同時(shí)還有要感謝本班及寢室的同學(xué)在設(shè)計(jì)期間給我的熱心幫助！參考文獻(xiàn)：[1] 李全利 ，遲榮強(qiáng)?！秵纹瑱C(jī)原理及接口技術(shù)》。北京：高等教育出版社，[2] 李廣弟，朱月秀，王秀山?！秵纹瑱C(jī)基礎(chǔ)》。北京：北京航空航天大學(xué)出版社，[3] 趙曙光，郭萬(wàn)有，楊頌華?！犊删幊踢壿嬈骷?，原理，開(kāi)發(fā)與應(yīng)用》。西安：西安電子科技大學(xué)，[4] 候伯亨?！禫HDL硬件描述語(yǔ)言與數(shù)字邏輯電路設(shè)計(jì)》。西安：西安電子科技大學(xué)出版社，1999[5] 王天曦 ，李洪儒?！峨娮蛹夹g(shù)工藝基礎(chǔ)》編著。北京：清華大學(xué)出版社，2000[6] 《單片機(jī)開(kāi)發(fā)》。 北京：人民郵電出版社[7] 付家才?！秵纹瑱C(jī)控制工程實(shí)踐技術(shù)》。北京：化學(xué)工業(yè)出版社，[8] 李光才， 樓然笛?！秵纹瑱C(jī)課程設(shè)計(jì) 實(shí)例指導(dǎo)》。北京：北京航空航天大學(xué)出版社 2004[9] 朱定華?！秵纹瑱C(jī)原理及接口技術(shù)實(shí)驗(yàn)》。北京：[10] 馬忠梅?！秵纹瑱C(jī)的C語(yǔ)言應(yīng)用程序設(shè)計(jì)》。北京：北京航空航天大學(xué)出版 社，[11] 《8031單片機(jī)時(shí)鐘系統(tǒng)的統(tǒng)設(shè)計(jì)》。北京：人民郵電出版社，[12] 弘道工作室?！度跁?huì)貫通 Protel99電路設(shè)計(jì)》。北京：人民交通出版設(shè)，2000[13] 張偉，王力，趙晶?！禤rotelDXP 入門(mén)與提高 》。北京：人民郵電出版社，第 29 頁(yè) 共 29 頁(yè)
