    它利用聚能射孔爆破技術，在預定地層位置將凍結管射穿，同時在地面利用凍結管及射孔彈道對特定地層進行注漿充填加固，既可實現井壁堵漏，又能減少由於地層沉降對井壁的垂直附加力。
  3. The paper applies ansys finite program to analyse coalstore - shale fired perforated brick ' s hole shape, and finds the factors that influence the strength of bricks. the author attempts to explore from the basic principle of heat transfer the effect of the changes of hole arrangements and hole ratios of the perforated ( hollow ) brick in certain dimensions on the thermal transition of the brick, and to improve the thermal insulation property of the brick on this basis

    通過ansys有限元應用軟體對不同孔型、不同孔排列的多孔磚進行力學性能分析，找出影響多孔磚力學性能的因素；探討了在一定尺寸條件下，多孔磚、空心磚的孔洞排列與孔洞率的變化對磚體傳熱性能的影響，以此改善磚體的抗壓強度和隔熱保溫性能。
  4. As for different requiremint for the lustration rate, we can provide you round - hole 20 - 30 %, strip - hole 40 - 50 % perforated panel. stringer, pedestal and typical rod with high - mechanic strength and loading capacity

    針對各種潔凈室潔凈度的不同需求，可提供圓孔20 % ? 33 % 、條孔40 % ? 50 %開孔率的高架鋁合金通風地板。支架、橫梁及特殊的斜撐設計為高承載，高強度奠定了堅實的基礎。
  5. Present the experimental research carried out on strain and stress by applying the resistance strain surveying technique to the big hole sealed heads in the new fire - tube heating boilers with the laws of strain and stress distribution obtained and allowable working pressure given because there is no applicable standards or specification for calculating the strength of crude oil heating boiler heads perforated by densely distributed big - holes, which, to a certain extent, hampered the further development of crude oil heating boilers in china, and concludes from experimental results that strain and the stress of circumference are fairly large near the edge of big - hole, and the cross ribs enhance strength of sealed head to a certain degree

    油田火筒加熱爐密集大開孔封頭的設計計算，因沒有相應的強度計算標準在一定程度上限制了我國油田火筒加熱爐技術的發展.採用電阻應變測量技術，對新型火筒加熱爐大開孔封頭進行了應力應變試驗研究，得到了封頭的應變和應力分佈規律，給出了大開孔封頭允許的工作壓力.試驗結果表明，大孔邊緣圓周處應力應變較大，十字筋板對封頭有一定加強作用
