【正文】 s misery, the cow told him to turn its hide into a pair of shoes after it died. The magic shoes whisked Niulang, who carried his two children in baskets strung from a shoulder pole, off on a chase after the empress. The pursuit enraged the empress, who took her hairpin and slashed it across the sky creating the Milky Way which separated husband from wife. But all was not lost as magpies, moved by their love and devotion, formed a bridge across the Milky Way to reunite the family. Even the Jade Emperor was touched, and allowed Niulang and Zhinu to meet once a year on the seventh night of the seventh month. This is how Qixi came to be. The festival can be traced back to the Han Dynasty (206 BCAD 220). Traditionally, people would look up at the sky and find a bright star in the constellation Aquila as well as the star Vega, which are identified as Niulang and Zhinu. The two stars shine on opposite sides of the Milky Way. Customs 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。在此向 宋老師 老師表示深深的感謝和崇高的敬意。例如：注意構(gòu)件的連續(xù)性，避免縱向構(gòu)件截面的空談；注意開口對強度的不利影響；上層建筑內(nèi)的縱、橫隔壁和支柱與甲板縱桁和橫梁相對等。 總布置設(shè)計的特點是涉及面廣、考慮因素多和實踐性強。 / ? 時， ? ?1 0. 07 / 2. 5f B d? ? ?； / ? 時， f取 。鋼料重量系數(shù) Ch一般在 Wh＝ ChLppBD （ ） Wh =*180**= 艤裝設(shè)備重量 Wf 按平方模數(shù)公式估算該項重量?？偨Y(jié)以上，總的設(shè)計思想是：保證艙容和航速要求下，減小本船主尺度。 相關(guān)母型資料 母型船載重量為 5800 噸，用于運載煤等散貨。因此。 8 動力裝置 主機機型選用 MAN Bamp。 2 航區(qū) 本船航行于我國近海區(qū)域 3 船級 本船由中國船級社登記入級。 10 繪制總布置圖（畫出總布置圖） 3 排水量和主尺度的初步確定 1 主要尺度 設(shè)計過程中綜合考慮船舶自身性能及經(jīng)濟(jì)性等因素。 參考文獻(xiàn) 5 航速 螺旋槳設(shè)計時考慮了主機功率儲備 12%，在船殼清潔無污底情況下，處于風(fēng)力小于蒲式風(fēng)力三級的平靜 深水水域條件下主機達(dá)到額定轉(zhuǎn)速時的試航速度為 kn。從船隊結(jié)構(gòu)情況看，我國干散貨船隊船舶噸位偏小，平均載重噸位低于世界平均水平。 散貨船特點是：單層甲板、尾機型、船體肥胖、航速較低，因散貨貨源充足，通常又專用碼頭裝卸 (如大型抓斗、氣動機械輸送等裝備 )，裝卸效率高，故船上可不設(shè)置起貨設(shè)備，其載貨噸位較大。 本船燃油、輕柴油的裝載量滿足船舶在滿載狀態(tài)，航速 Vs= 海里 /小時的續(xù)航力為 3500 海里。 根據(jù)公式 3 221 / krCbkkL ?? 可初步估算得到設(shè)計船船長 L=，再由公式1/kLB?、 2/kBd?， 3/KLD? 可以計算得到船寬 B、吃水 d 和型深 D。 (1) 求諾曼系數(shù) 2 ()3????? ? ? ?????h f mNW W W = () (2) 載重量增量 DW? ? ?1 1 1 1? ? ? ? ? ? ?D W D W D W D W LW=3700036618=382t () (3) 排水量增量 11??? ? ?N DW=458t () 代入浮性微分方程 bbCCddBBLL ????? ??????

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。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 37000 噸近海散貨船的主尺度確定及總布
