【正文】 s Day. More and more young Chinese people begin to celebrate this day in a very similar way as that in western countries. Fewer people than ever will gaze at the heavens on Saturday to pick out the two stars shining bright on either side of the Milky Way, that is, if people even know on which day Qixi falls. There are ready reminders dotted about, in the form of big ads saying Sales on Chinese Valentine39。 Festival. In this day, girls will throw a sewing needle into a bowl full of water on the night of Qixi as a test of embroidery skills. If the needle floats on top of the water instead of sinking, it proves the girl is a skilled embroiders. Single women also pray for finding a good husband in the future. And the newly married women pray to bee pregnant quickly. Tradition transformed The love story of Niulang and Zhinu, and the Qixi Festival have been handed down for generations. Yet these ancient traditions and customs are slowly dying out. Many modern Chinese, particularly youngsters, seem to know more about St Valentine39。s time for the wild fruits to ripe. The picturesque Arxan in Autumn is indeed a fairyland only exists in a dream that satisfies all your fantasies. If it rains heavily on Saturday night, some elderly Chinese 36 will say it is because Zhinu, or the Weaving Maid, is crying on the day she met her husband Niulang, or the Cowherd, on the Milky Way. Most Chinese remember being told this romantic tragedy when they were children on Qixi, or the Seventh Night Festival, which falls on the seventh day of the seventh lunar month, which is usually in early August. This year it falls on Saturday, August 2. Folklore Story As the story goes, once there was a cowherd, Niulang, who lived with his elder brother and sisterinlaw. But she disliked and abused him, and the boy was forced to leave home with only an old cow for pany. The cow, however, was a former god who had violated imperial rules and was sent to earth in bovine form. One day the cow led Niulang to a lake where fairies took a bath on earth. Among them was Zhinu, the most beautiful fairy and a skilled seamstress. The two fell in love at first sight and were soon married. They had a son and daughter and their happy life was held up as an example for hundreds of years in China. Yet in the eyes of the Jade Emperor, the Supreme Deity in Taoism, marriage between a mortal and fairy was strictly forbidden. He ordered the heaven troop to catch Zhinu back. Niulang grew desperate when he discovered Zhinu had been taken back to heaven. Driven by Niulang39。 ll wait in the line for one hour to get a ticket, and another two hours at the site, to only see a tiny bit of the place due to the crowds. Last year, 428 million tourists traveled in China over the weeklong holiday in October. Traveling during this period is a matter that needs thorough preparation. If you are short on time to plan the uping Golden Week it may not be a bad idea to avoid some of the most crowded places for now. There is always a place so fascinating that everyone yearns for. Arxan is a place like this. The beauty of Arxan is everlasting regardless of the changing of four seasons. Bestowed by nature, its spectacular seasonal landscape and mountains are just beyond word. Arxan is a crucial destination for the remended travelling route, China Inner Mongolia Arxan — Hailar — Manzhouli. It is also the joint of the four prairies across the SinoMongolian border, where people gravitate towards the exotic atmosphere mixed with Chinese, Russian, and Mongolia elements. As a historic site for the Yitian Battle, Arxan still embodies the spirit of Genghis Khan. Walking into Arxan, you will be amazed by a kaleidoscope of geous colors all the year round the Spring azaleas blooming red in the snow, the Summer sea wavering blue in the breeze, the Autumn leaves painted in yellow covering volcanic traces, and the Winter woods shining white on the vast alpine snowscape. Hinggan League Arxan city is situated in the far eastern area of Inner Mongolia Autonomous Region. Its full name Haren Arxan means hot holy water in the Mongolian language. Arxan is a tourism city in the northern frontier with a blend of large forest, grand prairies, vast snowfield, heaven lake cluster, thermium, as well as volcanic cluster. It is a rare and unique ecotourism base filled with healthy sunshine, clean air and unspoiled green. Nestled close to the country39。 最后 ， 我要 特別感謝指導(dǎo)老師李克旺副教授，他為我們提供了大量的學(xué)習(xí)資料和應(yīng)用軟件 ，并指導(dǎo)和幫助 我完成了本次設(shè)計 ?？傊?， 既 提升 了 自己的設(shè)計能力， 又鞏固了課本知識。同時，增進了同學(xué)間的友誼。 每個人都會遇到不同的困難，而對一個又一個的困難大家一起努力共同克服。 經(jīng)過一 個 多月 機械原理設(shè)計的學(xué)習(xí)及研究，我明白了許多在課堂上不懂的知識，也讓我深刻體會到實踐學(xué)習(xí)的重要性 ：實踐是學(xué)習(xí)的目的，也是學(xué)習(xí)的方法 。 在為課程設(shè)計寫說明書時，為了讓說明書 內(nèi)容更充實，使自己的書面語言更趨向于專業(yè)化，我們組到圖書館去借了相關(guān)的書籍來翻閱。在理論知識的貫穿上和用理論解決實際問題的能力上也亟待提高，可以說這次的設(shè)計就像是一面鏡子，照出了我的不足之處。換句話說，因這次課程設(shè)計我把理論與實踐運用結(jié)合了起來，達(dá)到了學(xué)以致用的目的。例如李老師告訴我們 在 使用六桿機構(gòu)時要注意其行程較小這一缺點； 由于 機械原理 課 本 中沒有涉及 間歇運動機構(gòu) 具體的計算公式 ，我去圖書館 借閱了 《 間歇運動機構(gòu)設(shè)計與應(yīng)用創(chuàng)新 》等相關(guān)書籍 ， 32 找到了相關(guān)公式；隨著自己對蜂窩煤成型機工作原理的進一步理解，我知道了生產(chǎn)率可轉(zhuǎn)化為轉(zhuǎn)速?? 當(dāng)然遇到的問題還有很多，我 基本上 在設(shè)計和計算過程中通過學(xué)習(xí)和實踐 解決了， 過程中和同學(xué)間討論也幫助我學(xué)習(xí)了不少經(jīng)驗和知識。 熟悉 了 相關(guān) 機構(gòu) 的設(shè)計方法， 初步 擬定 了 設(shè)計計劃。 拿到設(shè)計 題目 后，我就開始認(rèn)真 研 讀 設(shè)計任務(wù)書，明確設(shè)計內(nèi)容和要求，分析原始數(shù)據(jù)及工作條件 ；然后 通過 借閱（圖書館）、搜集（ 網(wǎng)絡(luò) ） 查找 有關(guān) 信息、資料 及 手冊；由于《機械原理》是上學(xué)期 課程，我 先 復(fù) 習(xí) 了機械原理 課程有關(guān)內(nèi)容 ，其中包括 ： 機構(gòu)的組成和結(jié)構(gòu)（自由度），連桿機構(gòu)（急回，壓力角，死點），凸輪機構(gòu)， 齒輪機構(gòu)，間歇運動機構(gòu)和組合機構(gòu)。機械原理
