【正文】 you feel much better.” He handed it to me and immediately hurried me through to a small room nearby for a rest. I felt better in no time. Soon I was back on my feet again and flowing him to collect a hovering carriage driven by puter. These carriages float above the ground and by bending or pressing down in your seat, you can move swiftly. Wang Ping fastened my safety belt and showed me how to use it. Soon I could fly as fast as him. However, I lost sight of Wang Ping when we reached what looked like a large market because of too many carriages flying by in all directions. He was swept up into the centre of them. Just at that moment I had a “time lag” flashback and saw the area again as it had been in the year AD 2008. I realized that I had been transported into the future of what was still my hometown! Then I caught sight of Wang Ping again and flew after him.The next day Pingyu was leaving London for Windsor Castle. “Perhaps I will see the Queen?” she wondered as she fell asleep.of the North of England, and the fourth, the Normans, left castles and introduced new words for food.The last day she visited karl Marx’s statue in Highgate Cemetery. It seemed strange that the man who had developed munism should have lived and died in London. Not only that, but he had worked in the famous reading room of the Library of the British Museum. Sadly the library had moved from its original place into another building and the old reading room was gone. But she was thrilled by so many wonderful treasures from different cultures displayed in the museum. When she saw many visitors enjoying looking at the beautiful old Chinese pots and other objects on show, she felt very proud of her country.I can still remember the moment when the space stewardess called us all to the capsule and we climbed in through a small opening. The seats were fortable and after a calming drink, we felt sleepy and closed our eyes. The capsule began swinging gently sideways as we lay relaxed and dreaming. A few minutes later, the journey was pleted and we had arrived. I was still on the earth but one thousand years in the future. What would I find?G: Good morning to all our visitors from 2008. First we’re going to examine one of the latest forms of munication among our space citizens. No more typists working on a typewriter or puter! No more postage or postcodes!

MY FIRST WORK ASSIGNMENT遼寧冠隆建設(shè)集團(tuán)公司作為于洪區(qū)國有企業(yè)，根據(jù)區(qū)政府總體要求和集團(tuán)未來發(fā)展需要，有意涉足節(jié)能保溫材料領(lǐng)域。 一個好的外保溫系統(tǒng)，應(yīng)具備良好的保溫隔熱性能、長久的使用壽命、良好的承載性和防火性。但我國目前的建筑節(jié)能水平，還遠(yuǎn)低于發(fā)達(dá)國家，我國建筑單位面積能耗仍是氣候相近的發(fā)達(dá)國家的3倍－5倍。在中國430多億平方米的建筑中，99%屬于高能建筑。二、保溫材料市場現(xiàn)狀1980年以前，我國保溫材料的發(fā)展十分緩慢，為數(shù)不多的保溫材料廠只能生產(chǎn)少量的膨脹珍珠巖、膨脹蛭石、礦渣棉、超細(xì)玻璃棉、微孔硅酸鈣等產(chǎn)品，礦棉廠很少，生產(chǎn)能力不足萬噸，散棉、硅酸鈣絕熱材料也只有3家，年產(chǎn)8000立方米，產(chǎn)品數(shù)量、質(zhì)量都滿足不了要求。2010年，伴隨著保溫工程的日益增多，工業(yè)保溫材料、設(shè)備生產(chǎn)行業(yè)的發(fā)展也將必將迎來一個新的高潮從2004年開始，沈陽市建筑業(yè)產(chǎn)值平均每年以27%的速度增長。產(chǎn)品特性： （9）本身無毒,不含CFC(氟氯化炭)和HCFC(氫氟氯酸)。在低溫深冷、地下工程、易燃易爆、潮濕以及化學(xué)侵蝕苛刻環(huán)境下使用時，不但安全可靠，而且經(jīng)久耐用，被譽(yù)為“不須更換的永久性隔熱材料”。計量單位使用溫度 體積吸水率9106/106（二）巖礦棉板產(chǎn)品概述：巖棉，也叫礦棉， 是一種用玄武巖為基材在1400℃左右的高溫狀態(tài)下進(jìn)行熔化抽絲做成的無機(jī)礦棉材料。技術(shù)性能及技術(shù)指標(biāo)： 　離心玻璃棉主要物理性能指標(biāo)項(xiàng)目單位指標(biāo)標(biāo)準(zhǔn)密度Kg/m310100GB/T 纖維平均直徑μ mGB/T 含水率%≤1GB/T 30071982燃燒性能級別不燃A級GB 86241997熱荷重收縮溫度℃≥250GB/T 118351988導(dǎo)熱系數(shù)w/m可廣泛用于建筑、化工、國防、冶金、電力、農(nóng)業(yè)、機(jī)械制造和交通運(yùn)輸?shù)炔块T。 (2)由于膨脹珍珠巖具有輕質(zhì)、隔熱、吸聲、不燃燒、不腐爛、不老化、不蟲蛀等良好性能，因此特別適用于建筑業(yè)的需要。 3．瀝青膨脹珍珠巖制品 瀝青膨脹珍珠巖制品是由膨脹珍珠巖與熱瀝青拌和而制成的。 5．膨脹珍珠巖裝飾吸聲板 （六）?；⒅橹破樊a(chǎn)品概述：產(chǎn)品由精選特殊粒徑的礦砂,在電爐加熱方式下膨化,通過對溫度和原料滯空時間的精確控制,使產(chǎn)品表面溶融,氣孔封閉,呈不規(guī)則球狀顆粒,內(nèi)部多孔空腔結(jié)構(gòu),表面玻化封閉,光澤平滑,理化性能十分穩(wěn)定新型保溫材料。 材料指標(biāo)粒度(mm)容重 (kg/m3)50200導(dǎo)熱系數(shù)(W/)成球率8095%表面?；省?5%吸水率(真空抽濾法測定的%)20501Mpa壓力的體積失率38%46%耐火度12801360186。技術(shù)要求：水泥膨脹蛭石制品物理性能指標(biāo)項(xiàng) 目 優(yōu)等品 一等品 合格品壓縮強(qiáng)度 MPa ≥ ≥ ≥密度 kg/m3 ≤350 ≤480 ≤55含水率 % ≤4 ≤5 ≤6導(dǎo)熱系數(shù)w/() ≤ ≤ ≤(平均溫度25177。 耐火、阻燃（墻板材—4小時耐火）：蒸壓加氣混凝土為無機(jī)物，不會燃燒，而且在高溫下也不會產(chǎn)生有害氣體；同時，蒸壓加氣混凝土導(dǎo)熱系數(shù)很小，這使得熱遷移慢，能有效抵制火災(zāi)，并保護(hù)其結(jié)構(gòu)不受火災(zāi)影響。使用時，也絕沒有放射性物質(zhì)和有害氣體產(chǎn)生，即使在高溫下和火災(zāi)中。 (10)適用各種建筑，特別是高層建筑。放 射 性：（2） 笨板安置于建筑物外墻或鋪設(shè)于地面，占用空間小，保溫效果明顯，便于設(shè)計建筑外型。厚度（mm）50性能特點(diǎn)：它最突出的特點(diǎn)是難燃、低煙、抗高溫歧變。八十年代先后在北京、上海等地引進(jìn)國外的巖棉、玻璃棉生產(chǎn)技術(shù)與裝備，開創(chuàng)了我國新型高效保溫絕熱材料的新時期，縮短了我國與西方發(fā)展國家在絕熱保溫材料領(lǐng)域的差距。能源緊缺，嚴(yán)重制約著國民經(jīng)濟(jì)發(fā)展和人民生活水平的提高；能源過度消耗還加劇環(huán)境污染和生態(tài)平衡的破壞。有機(jī)材料優(yōu)勢明顯在于造價較低，一般每平方米50元到80元，且保溫性能好且易施工。其中包括哈爾濱雙子星大廈大火、濟(jì)南奧體中心體育館大火等。不久亦傳入中國。）另外，巖棉和玻璃棉等無機(jī)材料作為保溫材料，在國際市場被廣泛采用，巖棉耐高溫最高使用溫度能達(dá)到650℃，玻璃棉也可以達(dá)到300℃。目前我們國家所 有的A級的保溫材料的生產(chǎn)能力加起來，不夠一個城市用。據(jù)調(diào)查，高品質(zhì)巖棉廠總料。本報告銷售價格以比較保守的3200元/噸計算，年銷售收入估算值為9600萬元。本項(xiàng)目生產(chǎn)線的技術(shù)關(guān)鍵是成纖技術(shù)、集棉技術(shù)、鋪氈技術(shù)三個環(huán)節(jié)，其主要特點(diǎn)：將離心機(jī)離心輥?zhàn)鴺?biāo)重新排列，使熔體流動路線與輥輪旋向符合，并增大了熔體對各成纖輥的包容面，提高了成纖率?；诽嵘龣C(jī)：將具有一定粒度且按工藝要求配制好的一定量原、燃料按沖天爐料位自動控制系統(tǒng)指令送入沖天爐加料皮帶。夾套與扁管內(nèi)為空氣程，內(nèi)膽內(nèi)部扁管外為煙氣程，煙氣與空氣逆向同軸流動。脫硫效率高達(dá)95%以上本系統(tǒng)裝備了完整的熱工測量、自動調(diào)節(jié)、控制、保護(hù)及熱工信號報警裝置。為了正常生產(chǎn)，離心機(jī)的控制柜對離心機(jī)各輥的冷卻水蒸氣和各輥軸承的油霧潤滑有報警顯示。鏈條導(dǎo)軌經(jīng)機(jī)械加工和熱處理安裝在導(dǎo)軌支架上。采用變頻電機(jī)帶動高速運(yùn)行，網(wǎng)帶下面布置有隨網(wǎng)傾斜的抽風(fēng)箱，可以根據(jù)生產(chǎn)情況調(diào)節(jié)負(fù)壓風(fēng)量。 縱向壓縮輸送機(jī) 縱向壓縮輸送機(jī)是采用消化吸收國外生產(chǎn)線的縱向壓縮輸送機(jī)而專門設(shè)計的。調(diào)節(jié)螺桿裝置的傳動由電機(jī)、傘齒輪減速機(jī)、傳動軸、萬向聯(lián)軸節(jié)、專用重型蝸桿減速機(jī)等組成。冷卻輸送機(jī) 給固化爐出來的棉板進(jìn)行強(qiáng)制冷卻，便于后道工序加工和產(chǎn)品包裝，且可改善環(huán)境溫度。當(dāng)測長裝置發(fā)出指令時，電磁離合器吸合，鋸片行車與主生產(chǎn)線同步運(yùn)行，切割鋸橫向運(yùn)行切割；當(dāng)切割完成時，電磁離合器斷開，鋸片行車停止運(yùn)行待命。沖天爐的鼓風(fēng)量，由流量計進(jìn)行測量，并通過數(shù)字調(diào)節(jié)器控制進(jìn)風(fēng)閥的開度來控制鼓風(fēng)流量。車間內(nèi)動力與照明，車間通風(fēng)空調(diào)，車間內(nèi)外生產(chǎn)線或照明所用全部電纜及橋架，以及車間外水、電、壓縮空氣供燃油或燃?xì)獾裙霉こ淘O(shè)。450元/立方米20000立方米/10000=900萬元根據(jù)《增值稅法》及其實(shí)施細(xì)則的有關(guān)規(guī)定，該項(xiàng)目中產(chǎn)品和商品銷售適用的增值稅率為17%，經(jīng)測算。 年均利潤總額投資利潤率=—————————100% 總資金 =—————————100% =% 累計凈現(xiàn)金流量開始 |上年累計現(xiàn)金凈流量|投資回收期= 1+ —————————— 出現(xiàn)正值的年份數(shù) 當(dāng)年現(xiàn)金凈流量 || =31+ —————— =(含建設(shè)
