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 。 -
In this thesis we firstly made all kinds of statistics on chinese character stroke information of chinese national standard code for information interchange ( gb2312 - 80 ), such as the average strokes of each chinese character and each character which uses utility frequency as its weight, the average strokes of each character been added weight or not that can be differed from the other characters, the number of chinese characters which begin with each stroke, the times of each stroke in the chinese character set, the chinese characters which have same strokes in the chinese character set, and the frequency of adjacent stroke, etc. according to the statistic, we have devised a new chinese character keyboard input method named " stroke code " by adopting the stroke sequence of hand - written chinese character as its input codes and designed a kind of key arrangement for the method
論文首先統計了國標二級字庫中漢字筆畫信息的各種數據，這些數據主要包括：漢字的平均筆畫數及按使用頻度加權的平均筆畫數、能與其它字區分開的漢字前若干筆畫的平均數與加權平均數、以各種筆畫起筆的漢字數、各種筆畫在漢字字庫中的出現次數、漢字字庫中筆畫相同的漢字以及漢字字庫中相鄰筆畫的頻度等。根據這些統計數據，我們採用書寫漢字時的筆畫順序作為漢字輸入碼，設計了筆畫碼漢字輸入法和實現該輸入方法的鍵盤。 -
Traditional grouping method could not use all attributes of entity and fuzzy correlation space based approach needed more match computation. fuzzy grouping method added two new techniques based on the fuzzy correlation space approach : fuzzy consistent relation based weight distribution and grid based preprocessing
由於傳統的分組方法不能充分利用實體所有的屬性，而基於模糊關聯空間的分組方法需要過多的運算量，本文提出一種模糊分組方法，該分組方法在基於模糊關聯空間方法的基礎上加入基於模糊一致性的權值分配方法和基於格子的預處理分組方法。
