  1. Vibrates the feeding engine in the production process, may massive, the granulated material from store in the bunker even, fixed time, to give continuously is expected in the installment, may evenly feed the material continuously in the sand and crushed stone production line for the stave machinery, and carries on the coarse fraction to the material, vibrates the feeding engine widely to use in professions and so on metallurgy, coal mine, dressing, building materials, chemical industry, grinding compound stave, in the screening combination plant

    振動給料機在生產流程中，可把塊狀、顆粒狀物料從貯料倉中均勻、定時、連續地給到受料裝置中去，在砂石生產線中可為破碎機械連續均勻地喂料，並對物料進行粗篩分，振動給料機廣泛用於冶金、煤礦、選礦、建材、化工、磨料等行業的破碎、篩分聯合設備中
  2. The results show that, composite could be fabricated on the complicated surface by means of sodium silicate sand mold combination with vacuum infiltration process. when the substrate was 10 mm, composite layers reached 3 mm to 5 mm in thickness with high strength interface and less casting defect. microstructures of grey cast iron and low chromium cast iron matrix composites with various volume fraction has been analyzed

    結果表明：用水玻璃砂型（芯）加負壓鑄滲的工藝能夠實現復雜表面（曲面）顆粒增強復合材料的制備，澆注方式簡單可靠，基材厚度在10mm時，復合層厚度能達到3 5mm ，且復合層鑄造缺陷少，復合效果好，界面緻密而且結合強度高。
  3. Erosive resistance of grey cast iron matrix composite has been investigated, on the condition of different volume fraction of wc and erosive angles and volume fraction of. the results showed that, the erosive resistance of composite with volume fraction of 27 wt % was the best ; volume abrasion rate of composites with different erosive angles was maximum at 50 angle, but volume abrasion rate was less at 0 and 70 angle ; on condition of the same volume fraction of wc and larger size of quartz sand in slurry, volume abrasion rate increased

    結果表明：碳化鎢體積分數為27的灰鐵基復合材料的耐沖蝕磨損性能最佳；不同沖蝕角下復合材料的體積碳化鎢顆粒增強鐵基表面復合材料及其沖蝕磨損性能研究摘要磨損量在50 「沖蝕角處最大，在0 」和70 」沖蝕角處較小；在碳化鎢顆粒體積分數相同的情況下，當漿料中的石英砂粒度大時，其體積磨損量增大。
  4. Abstract : based on analyzing the mechanism of fraction for anti - extraction soil by using the results of in - side model test about wind - borned sand deposit foundation, three stressing process of the ultimate bearing capacity in soil is given, and the basic formual for anti - extraction capacily calculation is established. compared with other methods at present, the accuracy of the calculation result is several times over that of others. because the scope of application isn ' t limited by width - to - depth ratio, it is very convenient for widely application

    文摘:利用風積砂地基抗拔室內模型試驗資料，通過對抗拔土體破壞機理的全面分析，提出了土體形成極限承載力的三個受力過程，建立了擴展基礎抗拔承載力計算的基本公式，與目前其它計算方法比較，成果精度提高很多倍，而且適用范圍不受深寬比限制，便於推廣應用。
