  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. The basic idea for hierarchy - based method is that creating and maintaining a tree of clusters and sub - clusters according to some kind of criterion to measure the distance of clusters, the procedure will be sloped until some terminal conditions are satisfied. hierarchical clustering method can be further classified into agglomerative and divisive hierarchical clustering, depending on whether the hierarchical decomposition is formed in a bottom - up or top - down fashion. most hierarchical clustering methods can produce the better results when the clusters are compact or spherical in shape. but they do not perform well if the clusters are any shape or there are outliers. a main reason is that the most hierarchical clustering methods employ medoid - based measurement as distance between clusters

    基於層次方法的聚類的基本思想足：根據給定的簇間距離度量準則，構造利維護一棵由簇利子簇形成的聚類樹，直至滿足某個終結條件為止。根據層次分解是自底向上還是自頂向下形成，層次聚類方法可以分為凝聚的（ agglomerative ）和分裂的（ divisive ） 。人多數層次聚類演算法在緊密簇或球形簇結構下能夠產生較好的聚類效果。
  3. Some characteristics of the measured wind pressure field were discussed, including distributions of wind pressure, the effects of shape ratio on total wind force coefficients, auto - and cross - power spectral density ( psd ) distributions of fluctuating wind pressure, characteristics of the proper orthogonal decomposition ( pod ) results of the measured wind pressure field, effects of reynolds number on wind pressure distributions, etc

    根據測量結果對殼體表面風壓場特性進行了分析，包括風壓系數、整體風力系數、脈動風壓自功率譜及互功率譜、風壓場本徵正交分解特性、雷諾數對殼體表面風壓分佈的影響等。
  4. For shape optimization of truss structure, the design variables are separated into two kinds of bar sectional size and nodal position by multilevel decomposition optimization method

    對于桁架結構形狀優化，應用層次分解優化方法，將設計變量分成桿件截面積和節點位置兩類變量。
  5. On the basis of this work, the cnx nanotubes with " nested - cone " shape have been produced by thermal decomposition at 780 - 980 with nhb released from nh4cl as nitrogen source

    在此實驗基礎上選用氯化銨釋放出的氨氣為氮源，制備出了「錐形嵌套"結構的cn _ x納米管。
  6. For shape modeling and detection, a shape representation algorithm based on morphological shape decomposition is proposed. based on the decomposition scheme, we construct a fuzzy attributed relational graph by learning from training examples as the shape model. a hierarchical part - based shape detection algorithm is developed based on such a model

    在形狀建模和檢測的研究中，提出了一種基於形態學形狀分解的形狀描述演算法;在此基礎上，通過樣本學習，得到模糊關系屬性圖作為形狀模型;根據該模型，提出了一種基於部分的層次式形狀檢測方法。
