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 jump When 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. 南華大學(xué)船山學(xué)院單片機(jī)課程設(shè)計(jì) 第 27 頁 共 29 頁 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 there 8 致謝 這次單片級的課程設(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)到了許多書本上沒有的知識，加強(qiáng)了自己個(gè)方面的能力，尤其是在動手能力方面更為明顯，看到自己辛辛苦苦做出來的電路板，所說有點(diǎn)累但別 提有多高興，最重要是從中體會到了學(xué)習(xí)的快樂。從此樹立了自己學(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 ！ 南華大學(xué)船山學(xué)院單片機(jī)課程設(shè)計(jì) 第 28 頁 共 29 頁 參考文獻(xiàn)： [1] 李全利 ， 遲榮強(qiáng) 。 《單片機(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 。 《單片機(jī)基礎(chǔ)》 。 北京 ： 北京航空航天大學(xué)出版社 ， [3] 趙曙光，郭萬有 ， 楊頌華 。 《可編程邏輯器件，原理，開發(fā)與應(yīng)用》 。 西安 ： 西安電子科技大學(xué) ， [4] 候伯亨 。 《 VHDL 硬 件描述語言與數(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 。 《電子技術(shù)工藝基礎(chǔ)》編著 。 北京 ： 清華大學(xué)出版社 ， 2021 [6] 《單片機(jī)開發(fā)》 。 北京 ： 人民郵電出版社 [7] 付家才 。 《單片機(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 。 《單片機(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 2021 南華大學(xué)船山學(xué)院單片機(jī)課程設(shè)計(jì) 第 29 頁 共 29 頁 [9] 朱定華 。 《單片機(jī)原理及接口技術(shù)實(shí)驗(yàn)》 。 北京 ： 北方交通大學(xué)出版社 [10] 馬忠梅 ?！秵纹瑱C(jī)的 C語言應(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 。 《融會貫通 Protel99 電路設(shè)計(jì)》 。 北京 ： 人民交通出版設(shè)， 2021 [13] 張偉，王力，趙晶 。 《 ProtelDXP 入門與提高 》 。 北京 ： 人民郵電出版社 ，
