【正文】 是對自己能力的一種提高。 我也 明白 了 學(xué)習(xí)是一個長期積累的過程,在以后的工作、生活中都應(yīng)該不斷的學(xué)習(xí),努力提高自己知識和綜合素質(zhì) ,只有自己親身經(jīng)歷了,好多問題的精髓才能 真正的接受,只有自己用心鉆研了才會發(fā)現(xiàn)其中的精華和奧秘所在,并且在研究的過程中自己會獲得更多的想法和思路,學(xué)習(xí)到更多意料之外的新知識,學(xué)到更多書本上學(xué)不到的知識 。 此外,還得出一個結(jié)論:知識必須通過應(yīng)用才能實現(xiàn) 其價值!有些東西以為學(xué)會了,但真正到用的時候才發(fā)現(xiàn)是兩回事,所以我認為只有到真正會用的時候才是真的學(xué)會了。在設(shè)計過程中,我通過查閱大量有關(guān)資料,與同學(xué)交流經(jīng)驗和自學(xué),并向老師請教等方式,使自己學(xué)到了不少知識,也經(jīng)歷了不少艱辛,但收獲同樣巨大。而且大大提高了動手的能力,使我充分體會到了在創(chuàng)造過程中探索的艱難和成功時的喜 悅。 基于 51 單片機的電梯控制系統(tǒng) 13 13 參考文獻 [1] 葉挺秀 .應(yīng)用電子學(xué)[M] .杭州:浙江大學(xué)出版社, 1994 [2] 朱承高 .電工及電子技術(shù)手冊[M] .北京:高等教育出版社, 1990 [3] 閻 石 .數(shù)字電子技術(shù)基礎(chǔ)(第三版)[M] .北京:高等教育出版社, 1989 [4]李朝青 .單片機原理及接口技術(shù)[M] .北京 :北京航空航天大學(xué)出版社, [5]李廣弟 .單片機基礎(chǔ)[M] .北京 :北京航空航天大學(xué)出版社, [6]曹巧媛 .單片機原理及應(yīng)用[M] .大連:連理工大學(xué)出版社 .

Always feel oneself should go to do something, or write something. Twenty years of life trajectory deeply shallow, suddenly feel something, do it. 一字開頭的年齡已經(jīng)到了尾聲??傆X得自己自己似乎應(yīng)該去做點什么,或者寫點什么。 The end of our life, and can meet many things really do? 而窮盡我們的一生,又能遇到多少事情是真正地非做不可?

Those who do, just green years oneself give oneself an arm injection, or is a selfrighteous spiritual. 一個人的時候,自己的想法總是特別地清晰。也曾經(jīng)好像已經(jīng)下定了決心去做某件事,但更多的時候是最后又打起了退堂鼓。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心劑,或者說,是自以為是的精神寄托罷了。 Those were broken into various shapes of stationery。 Have declared the end of the encounter that haven39。突然想到那件藍格子襯衫;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;還有那場還沒有開始就宣告了終結(jié)的邂逅計劃 …… 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。ll be traveling fast, so despite the distance, it will not be like diving into the deep end of a pool.

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. 基于 51 單片機的電梯控制系統(tǒng) 24 24 If he goes too fast or spins out of control, he has a stabilization parachute that can be deployed to slow him down.
