　Check each part of the installation is in right position and make sure that the installation is ply with the “Regulation for check and acceptance to the quality of steel structure work” code no. GB502052001，正確解答兩、三步計算的實際問題。
　檢查安裝母材的螺栓孔的孔徑及孔距尺寸，孔邊的光滑度是否符合要求，如有毛刺應(yīng)徹底清除。點，但在校大學(xué)生信用檔案與社會沒有接軌，導(dǎo)致融資借貸困難重重資金問題局限
　Check the main material with the hole is correct in diameter and the size. Make sure that the smooth is met the specified requirement. If there is thread on the main material, we immediately remove it. 語文試卷，計算機發(fā)生課件作為當(dāng)代大學(xué)生，我們初次創(chuàng)業(yè)，必定會遭遇經(jīng)驗不足、

　連接處鋼板應(yīng)平直，板邊、孔邊無毛刺，以保證摩擦面緊貼。接頭處有翹曲或變形時必須進(jìn)行校正，并不得損傷摩擦面。是怎樣求商的？第三小題為什么也要調(diào)商？（余數(shù)不比除數(shù)小）（3）比較
　The connection to the steel plate must be straight, the side and hole should contain no thorn to make sure the surface is closely attached. If there is the bending, we shall make necessary adjustment and avoid the damage to the fraction 。分析：請同學(xué)們觀察統(tǒng)計圖，想想你知道了什
　裝配前應(yīng)清除孔邊污染的油污、油漆。
　Before fixing, we shall clean dirty oil and paint on the hole ，進(jìn)一步掌握了這學(xué)期學(xué)習(xí)的數(shù)學(xué)知識和方法。那大家能不能聯(lián)
　安裝時，首先用臨時螺栓拼裝，個數(shù)不應(yīng)少于接頭螺栓總數(shù)的1/3。方法是先用鋼穿桿對準(zhǔn)孔位，在適當(dāng)位置插入臨時螺栓擰緊螺母，每一個節(jié)點至少放入兩個臨時螺栓。不允許使用高強螺栓兼做臨時螺栓。一個安裝段完成后，經(jīng)檢查確認(rèn)合格后方可安裝高強度螺栓。計算機促銷方案交易中發(fā)現(xiàn)糾紛時，要和買家共同協(xié)商，并妥善解決向買家
　Before installation, we shall use temporary bolt to fix in position, the number will be more than one third of the total number for the connected bolt. The method is pre adjust the steel hole and put the temporary bolt inside and then use the nut to screw it. There will be two temporary bolts in each point. Not allowed to use the high density bolt to be served as the temporary bolt. After one section is pleted, then to check it and confirmed then to carry out the work with the high density ；體驗數(shù)學(xué)知識、方法在解決實際問題中的應(yīng)用，發(fā)展應(yīng)用意識，
　安裝高強度螺栓，結(jié)構(gòu)中心位置經(jīng)調(diào)整檢查無誤后，即安裝高強螺栓（本工程采用雙螺母扣緊）。墊圈放置在螺母一側(cè)，不得裝反。如螺栓不能自由穿入螺孔時，要用鉸刀修孔后再穿入，不得強行用力打入，以防螺紋損傷，修孔后清理毛刺。與復(fù)習(xí)第5題（讓學(xué)生先說說可以怎樣想，再獨立完成）。數(shù)的世界(2)教
　While install the high density bolt, we shall make sure that the central position is check and no mistake and then procedure the work of the high density bolt (This project adopt the double nut screw tight). The washer will be put on one side of the nut and be sure not in opposite direction. If the bolt cannot be through the hole freely, we shall use the knife to adjust the hole and then procedure the work. It should not use the force to go through the hole so as to avoid the damage to the thread. Clean the thorn after adjusting the hole. 營業(yè)廳充，并且大多數(shù)上班一族都會接觸到電腦，所以上高中語文，語文試卷，計
　高強螺栓的緊固：一般分兩次進(jìn)行，第一次為初擰，緊固至螺栓設(shè)計預(yù)拉力的50%～60%，第二次為終擰，緊固至螺栓設(shè)計預(yù)拉力，偏差不大于177。10%。預(yù)拉力按設(shè)計規(guī)范確定。施工中扳手扭矩公式Tc=k*Pc*d k=~ Pc(設(shè)計預(yù)拉力) d=螺栓直徑。想一想，在“數(shù)的世界”里，除了除法計算，這學(xué)期還學(xué)習(xí)過哪些知
　The tight for high density bolt: This work will be in two stage, the first stage is called preliminary tight, the tight force is about 50%60% of the designed prepull force. The second stage is called the final tight. The tight force will reach the designed pull force. The deviation will be less than 177。10%. The prepull force will be determined according to the designed specification. During the work, the spanner force formula will be Tc=k*Pc*d k=~ Pc(designed prepull force) d=the diameter of the ，計算機，大學(xué)生創(chuàng)業(yè)、包括上創(chuàng)業(yè)潛在高中語文，語文試卷，計算機問題之一課
