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. 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 北京師范大學(xué)珠海分校信息學(xué)院 6 北京師范大學(xué)珠海分校 本科生畢業(yè)論文 論文題目 : 中小學(xué)教育軟件的分析 學(xué) 院 專 業(yè) 學(xué) 號(hào) 學(xué) 生 姓 名 指導(dǎo)教師姓名 指導(dǎo)教師職稱 指導(dǎo)教師單位 年 月 日 北京師范大學(xué)珠海分校信息學(xué)院 7 摘 要 本論文通過對(duì)當(dāng)前一些中小學(xué)教育軟件的分析,以及教育軟件開發(fā)技術(shù)的考察,以小組成員自主開發(fā)的一個(gè)教育軟件為例,對(duì)教育軟件開發(fā)過程的一些技術(shù)問題提出一些實(shí)用性的建議及實(shí)現(xiàn)。論文首先從教育軟件的整個(gè)發(fā)展現(xiàn)況與前景進(jìn)行分析,提出了教育軟件需面對(duì)以及注意的幾個(gè)問題,在客觀地分析當(dāng)前大多數(shù)的教育軟件的優(yōu)點(diǎn)以及缺點(diǎn)的過程中,提出了一些個(gè)人對(duì)于教育軟件的設(shè)想與建議。 在此基礎(chǔ)上,本論文以自主研發(fā)的一款教育軟件做為研究對(duì)象,以 Flex Builder 做為主要開發(fā)工具,由功能設(shè)計(jì),框架設(shè)計(jì),數(shù)據(jù)組織 ,代碼組織等各個(gè)方面對(duì)一款教育軟件的開發(fā)過程做出一定的實(shí)踐,在實(shí)現(xiàn)一款教育軟件的同時(shí),總結(jié)經(jīng)驗(yàn),并將前期的整體設(shè)計(jì),中期的具體編碼實(shí)現(xiàn),后續(xù)的軟件測(cè)試的具體思路以及核心代碼呈現(xiàn)在論文中。 關(guān)鍵詞: 教育軟件;信息技術(shù); Flex;游戲開發(fā);程序設(shè)計(jì); 北京師范大學(xué)珠海分校信息學(xué)院 8 EDUCATIONAL SOFTWARE OF PRIMARY AND SECONDARY CHARACTERISTICS DESIGN AND DEVELOPMENT OF FLOWER CROSSWORD ABSTRACT The paper on the current number of primary and secondary education through the analysis of software and educational software development technology, visits to members of the group developed an educational software, for example, for educational software development process a number of technical issues and implementation of a number of practical the whole development of education software to analyze the current situation and prospects, and then to Flex Builder as the main development tool, an educational software in achieving the same time, sum up experience, and the development of design ideas, and the code presented in the paper.
