  2. Abstract : in order to make use of perlite resources and solve traditional expansion perlite in application, a spherical closed pore expansion perlite with the properties of high strength and low water - absorbing has been developed

    文摘:為解決珍珠巖礦產資源利用及傳統多孔膨脹珍珠巖在使用中存在的問題，研製成功一種強度高、吸水率低的球形閉孔膨脹珍珠巖。
  3. Abstract : reviewed are five methods for the analysis of the penetration of jacked - in piles, namely, cavity expansion method, strain path method finite element method, slip line method and calibration model test. after analysis, it is pointed out that it is more rational to adopt sub - statical spatial axisy numerical formulas based on traditional plane - strain cavity expansion method in the analysis. after spatial closed - form solutions are obtained for soil movements, stresses and initial excessive pore pressures generated durihy pile penetration are found out. it is suggested that finite element analysis together with centrifugal model test be used in verifying the results

    文摘:在分析飽和粘土中靜壓樁的貫入機理的基礎上，對靜壓樁沉樁分析的圓孔擴張理論、應變路徑法、有限元分析、滑移線理論和模型槽試驗等五種方法逐一進行評述，並提出在傳統的平面圓孔擴張理論基礎上加以改進，採用準靜態空間軸對稱方程組對靜壓樁貫入過程進行模擬，從而得出土體位移、應力、初始超孔壓的空間解析解，同時採用有限元分析、模型槽試驗相互印證的研究方法
  4. In this paper closed - cell foam samples with basically controllable pore structure and uniform distributed pore were prepared by means of melt foaming technique ( mft ). by relative theory analysis and adjusting the content of foam agent, foaming temperature, stirring time and hold time, means of getting samples with high quality has been found

    本文採用熔體發泡法，通過相關理論分析和控制發泡溫度、攪拌時間、保溫時間、調節發泡劑含量等制備出了孔結構基本可控、孔洞分佈均勻的閉孔泡沫鋁樣品。
  5. Compared with those of as - sprayed ring, hardness and tension strength of area near processing face are increased by 45 % and 40 % respectively. friction mechanical performance of the ring is improved at large extent, and especially the wearing amount is merely 13 % of as - sprayed rings. after dual - direction cyclic pressing, the pore - closed state and the distributing of density and hardness are nearly identical in every part of ring. the friction mechanical property is close to that of single - direction - cyclic - press ring

    靠近壓力加工面部位，硬度較沉積坯提高了45 % ，拉伸強度較沉積坯提高了40 % 。雙向楔壓后孔洞閉合、密度硬度分佈都比較均勻。單向楔壓后，用壓力加工面作為摩擦面， al - 20 % si / sicp復合材料的摩擦磨損性能得到大幅度提高，尤其磨損量為楔壓前的13 % 。
