  1. The results indicated that the dimension, shape and purity of base material could meet the functional demand of solid lubricant ; the thermal decomposition temperature of ptfe resin exceeds 400 c, but organic and inorganic packing filler added in ptfe made the water absorption rate of composite material increased, melting temperature and decomposition temperature decreased, in the meanwhile oxidative decomposition reaction was accompanied ; polar groups such as c = o, c - o - c and so on in the carbon fiber surface is advantageous to increase compatibility with other components and interlayer shearing strength ; uniform design experimental method could help to find the relationship between formula and frictional property by relatively small tests. the developing trend of each formula ' s friction coefficient could be showed by fitting curve ; the friction coefficient with no copper powder or graphite in formula was relatively big. this fact showed that copper powder and graphite should be used cooperatively ; it was found that when the ratio of copper powder to graphite by weight is 15 : 60, 30 : 30 - 40 and 60 : 15 - 30 respectively, the friction coefficient was relatively small. the degree of crystallinity of pure ptfe reached maximum by air cooling and the abrasion loss also reached maximum among three ones ; at the same time, the abrasion loss of solid lubricant sample was also the biggest among three ones ; when solid lubricant matched with 45 # steel axle or gcrl5 steel axle, lubricant transfer film could be formed on metal surface, thus direct contact between the surface of metal friction pair rings was reduced. their working life was elongated extremely ; there was mainly much graphite, a little ptff, moo3, feso4, cus and so on in lubricant transfer film

    試驗結果表明：所選原料的尺寸、形狀及純度可滿足固體潤滑劑的性能要求；聚四氟乙烯樹脂熱分解溫度超過400 ，但在ptfe中加入無機填料會使復合材料吸水率提高，熔融溫度及分解溫度降低，且伴有氧化分解反應；碳纖維表面含有c = o及c - o - c等極性基團，有利於提高其與其它組分的相容性，提高層間剪切強度；均勻設計試驗方法能夠用較少的試驗次數找出配方與摩擦性能間的關系，擬合曲線基本能表示各配方的摩擦系數發展趨勢；配方中不加銅粉或不加石墨，其摩擦系數均較高，說明銅粉和石墨應該配合使用；當銅粉15份、石墨60份時，銅粉30份、石墨30 - 40份時，銅粉60 、石墨15 - 30份時，摩擦系數均具有較低值；純聚四氟乙烯樹脂在空氣冷卻時結晶度最大，磨損量也是三者中最大的；同時，固體潤滑劑試樣在空氣冷卻時的磨損量也是三者中最大的：不論是固體潤滑劑與45 #鋼軸配副或是固體潤滑劑鑲嵌入銅套后與gcr15鋼軸配副，在金屬表面均可形成潤滑轉移膜，從而減少金屬摩擦副表面間的直接接觸，大大延長其使用壽命;轉移膜中主要含有較多的石墨、少量聚四氟乙烯、 moo 。
  2. In this research, through the test in geometric parameter and resistance performance, and comparison between random and other stacked packing, pvc screw thread oblique corrugated plate have more advantage. combined with test and theoretic calculate, determined the heat and mass transfer coefficient, obtained the influence relationship between inlet air flow rate, temperature and humidity, inlet liquid desiccate flow rate, temperature and concentration with outlet air humidity in dehumidifier, provided consideration for equipment design and production

    通過對除濕塔的現場測試並結合理論計算，確定其熱質交換系數，並分析得出採用pvc螺紋斜波紋板填料的一定結構的除濕塔，處理空氣的風量、入口溫度和含濕量及除濕溶液流量、入口溫度和濃度對空氣出口含濕量的影響關系，為除濕設備的設計和指導生產運行提供參考。
  3. A comparison of the optical and mechanical performance is made between with iad and without iad. the optical performances include the refractive index the extinction coefficient the packing density the vaccum - to - air shift and the afm images of the surface ; the mechanical performances include the adhesion and the hardness

    光學特性涉及折射率、消光系數、波長漂移、聚集密度和表面粗糙度，機械特性涉及硬度和附著力。通過研究，發現離子輔助沉積對單層薄膜的光學特性和機械特性均有明顯改善。
  4. By using ec membrane material as column packing, double - distilled water as mobile phase, the retention times ( tr " ) are measured with suitable inorganic and organic compound as solutes. 3. complying with the retention times, the partition coefficient of the solute ( ka " ) and the ratio of the surface excess concentration of solute ( ) with the concentration of the parent fraction ( cab ) are calculated

    利用物理改性的方法研製了乙基纖維素（ ethylcellulose ，簡稱ec ）膜材料，並將其作為高效液相色譜柱的固體填料，以高效液相色譜模擬反滲透實驗平衡條件，以水為流動相，選擇合適的無機物和有機物作為溶質，測定乙基纖維素對它們的相對保留時間及平衡分配常數k _ a 。
