【正文】 ustoms In bygone days, Qixi was not only a special day for lovers, but also for girls. It is also known as the Begging for Skills Festival or Daughters39。s Day! in shops, hotels and restaurants. But few young women will mark the festival with their boyfriends, or take part in traditional activities to pray for cleverness. A largescale of exhibition on the Silk Road opened to the public in the National Museum on Thursday. The exhibition displays more than 400 treasures from Shaanxi province, Gansu province and 14 other regions. It is largest scale exhibition that shows the history of the Silk Road in recent years. As APEC is going on in Beijing, the exhibit aims to show the world this brilliant section of history. The Silk Road is a series of trade and cultural transmission routes that were central to cultural interaction through regions of the Asian continent. It connected the West and East by linking traders, merchants, pilgrims, monks, soldiers, nomads, and urban dwellers from China and India to the Mediterranean Sea during various periods of time. I met my dear hubby in 2021 the second year I was in my school and it was the first year when he came here. We became colleagues. And there was nothing special happening during that year. He was just a kind and humble brother graduated from the same college as me. But we did not know each other till he became my colleague and his office desk was just in front of me. There was only a glass between us. So actually we could see each other when we both look up. But it is not the main reason that really draws us close. How we bee close to each other was something seems quite natural. We went out to play badminton with other colleagues and we sometimes chatted for a while. He is a man of few words but somehow sometimes will say something really humorous. Then one day, to my great surprise, I found a pot of beautiful flower on my desk. It was just the flower I had talked about with my colleague the other day, and I t。s Day on February 14, characterized by bouquets of roses, chocolates and romantic candlelight dinners, than they do about their homegrown day for lovers. Even Qixi is nowadays referred to as the Chinese Valentine39。s largest virgin forest, and known for its spring and ecological environment, Arxan is marveled at by many tourists as the purest land on earth. You cannot miss out the Autumn of Arxan. It is definitely the best with brightlycolored scenery full of emotions. Autumn in the northern part of the country es earlier than the South. A September rain followed by the footprints of Autumn brings more colors to the once emerald green mountain and blooming grassland. Shutterbugs flock to see for themselves the marvel of splendid colors around the mountains and waters, many of whom have travel a long distance and even camp here only to capture a moment of the nature wonder. The silver birch turns golden, while the larch is still proudly green. You will find yourself drowned in the intoxicating red of the wild fruits as well as the glamour of flowers in full blown. And your heart will be lingering on the woods as it39。 ——正文中未被引用但被閱讀或具有補(bǔ)充信息的文獻(xiàn)。 ③ 下列內(nèi)容可以作為附錄編于論文后： ——為了整篇論文材料的完整，但編入正文又有損于編排的條理性和邏輯性，這一材料包括比常州大學(xué)本科生畢業(yè)設(shè)計(jì)（論文） （居中 宋體 小四號(hào)） 第 頁 共 頁 （居中 宋體 小四號(hào)） 正文更為詳盡的信息、研究方法和技術(shù)更深入的敘述， 對(duì)了解正文內(nèi)容有用的補(bǔ)充信息等。 ④ 給予轉(zhuǎn)載和引用權(quán)的資料、圖片、文獻(xiàn)、研究思想和設(shè)想的所有者。 常州大學(xué)本科生畢業(yè)設(shè)計(jì)（論文） （居中 宋體 小四號(hào)） 第 頁 共 頁 （居中 宋體 小四號(hào)） 致 謝（居中 宋體 四號(hào) 粗體） （字間空一格） （空一行） 內(nèi)容（宋體 小四號(hào)） 謝詞應(yīng)謙虛誠(chéng)懇，實(shí)事求是。 示例：北京：科學(xué)出版社， 2021 （原題：科學(xué)出版社 北京 上海 2021） ④ 正文中引用文獻(xiàn)的標(biāo)注方法采用順序編碼制，即按正文中引用的文獻(xiàn)出現(xiàn)的先后順序連續(xù)編碼，并將序號(hào)置于方括號(hào)中。超過 3 個(gè)時(shí)，只著錄前 3 個(gè)責(zé)任者，其后加 “，等 ”或與之相應(yīng)的詞。 ③ 參考文獻(xiàn)表應(yīng)置于正文后 ，并另起頁。結(jié)論應(yīng)準(zhǔn)確、完整、明確、精煉。應(yīng)言簡(jiǎn)意賅，不要與摘要雷同，不要成為摘要的注釋。 ?1 = u11 u12u21..........................................................................................................（ 1）（或 ） 說明： ① 論文中的公式應(yīng)另起行，并縮格書寫，與周圍文字留足夠的空間區(qū)分開。 ② 表的編排采用國(guó) 際通行的 三線表 。 冷卻系統(tǒng)的設(shè)計(jì) 冷卻系統(tǒng)的設(shè)計(jì)原則包括： （ 1）冷卻水道的設(shè)置應(yīng)均勻的布置在動(dòng)定模和型腔四周； （ 2）冷卻水孔的孔間距越小，直徑越大，則對(duì)塑件冷卻越均勻； （ 3）水孔與相鄰型腔表面距離相等； （ 4）采用并流流向，加強(qiáng)澆口處的冷卻。 推出機(jī)構(gòu) 使用 8 216。 本設(shè)計(jì)中將楔緊塊與定模型芯固定板做成一個(gè)整體，增加強(qiáng)度。 楔緊塊 當(dāng)塑料熔體注入型腔后，它以很高的壓力作用于瓣合模塊，迫使滑塊后退，其 作用 力等于塑料壓力和沿滑動(dòng)方向塑料作用在型芯或模板上投影面積的乘積。 抽拔距的計(jì)算 最小抽拔距 221S R r?? 常州大學(xué)本科生畢業(yè)設(shè)計(jì)（論文） （居中 宋體 小四號(hào)） 第 頁 共 頁 （居中 宋體 小四號(hào)） S1=36mm 設(shè)計(jì)抽拔距 S=S1+（ 2~3） mm S=38mm 斜銷計(jì)算 斜銷的角度 α=20176。 成型零件的結(jié)構(gòu)設(shè)計(jì) 構(gòu)成模具型腔的零件統(tǒng)稱為成型零件。常見的澆口形式有邊緣澆口、扇形澆口、平縫澆口、圓環(huán)澆口、輪輻澆口、爪型澆口、點(diǎn)澆口、潛伏式澆口、護(hù)耳澆口、直澆口等十種。主流道襯套要求承受交變應(yīng)力，其外圓盤直徑不能
