The minimum shear resistance of beams in the paper is close to the one in the code for design of concrete structures " gb50010 - 2002 '. according to the actual project, the destroy of 448 kinds of beams are analyzed by computer by taking account of the effective coefficient " " of the strength of concrete confined by hoops, the relationship with the section property of beams, the critical point of the arch - rib failure transiting to the shear - compression failure which is advanced in the anti - theory, and the contribution to the beam ' s shear resistance of the concrete in the shear - compression zone
引用箍筋約束混凝土的有效系數，利用其與梁截面特性的關系並結合理論分析中提出的梁剪壓破壞與斜壓破壞的分界點，同時考慮了剪壓區混凝土的抗剪貢獻，從工程實際出發，編程擬算了448種梁構件的破壞情況，計算結果表明，梁發生在剪壓破壞范圍內的最大抗剪承載力值比混凝土結構設計規范gb50010 - 2002值略高。 -
These machines are whole - close structure double - knit circular knitting machine of 2 - track in dial and 4 - track in cylinder, which can be used to produce various kinds of compound stitches fabrics combining with tuck and float stitches based on rib and interlock stitches
上述機型繫上2下4全封閉結構的雙面圓緯機，可編織羅紋或雙羅紋為基礎的可與集圈、浮線相結合的各類變換組織的坯布。 -
Secondly, the temperature distribution in rib - tube heat exchanger in the course of heat transfer is programed and simulated using apdl language of fem software ansys, and the average convection coefficient of both sides is obtained. the rib - tubes with different structure are also simulated and optimized on the base of the calculated results, the relationship between structure and the average convection coefficient of both sides is summrized. the rib - tube structure is optimized using apdl. finally, combines numerical simulation with experimental research, and results of numerical simulation are found to be close to the experimental data
利用ansys有限元程序對翅片管換熱器的換熱過程進行數值模擬，確定了換熱過程中翅片管的溫度場和熱流量梯度分佈狀況，對翅片管換熱器的多組分流場進行計算，給出了逆流和順流兩種情形下翅片管結構參數對換熱效果的影響規律，並利用ansys提供的優化技術編寫程序對翅片管進行結構優化設計，為其今後在工業中的設計及使用提供了重要依據。
