  1. These may be either narrow informal elongations of the park, varying say from 200 to 500 feet in width and radiating irregularly from it, or if, unfortunately, the town is already laid out in the unhappy way that new york and brooklyn, san francisco and chicago are, and, i am glad to say, boston is not, on a plan made long years ago by a man who never saw a spring carriage and who had a conscientious dread of the graces, then we must probably adopt formal parkways

    也許會有一些狹隘的不正式的對到公園路,以及從公園不規則的輻射出的200到500英尺寬不的道路,或者,如果,不幸的是,城市已經按照一種令人不愉快的方式發展了,就像紐約,布魯克林,舊金山和芝加哥那樣,當然,我可以興的說,這不包括波士頓,在很久以前一個無視春天的氣息並且對一切美好事物都充滿無盡的恐懼的糟老頭制定出了這糟糕的城市建設計劃,所以,我們大概必須使用正規的道路做
  2. 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,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極性基團,有利於提其與其它組分的相容性,提層間剪切強度;均勻設計試驗方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,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 。
  3. Furthermore, the growth and the study of self - organized quantum dots structures become more and more important recently, and the application of self - organization technique become wider and wider in this thesis, we address the theory of film growth and the growth technique firstly more, the ways and characteristics of surface detection are prescribed we mainly report the growth process, results and discuss of self - organized quantum dots structures in the a12o3 substrates by s - k mode using ecr - mocvd, in the espd - u device the growth art of ain epilayer which is the preliminary foundation of self - organized gan / ain quantum dots structures, including the substrate cleaning, nitridation, the growth of buffer and the growth of gan and ain epilayer, is discussed we deliberately compare the test result of rheed xrd and afm and achieved the optimalized condition of ain at last we have successfully realized the growth of ain which is much smooth and better crystal quality moreover, we grow the self - organized gan / ain quantum dots structure in s - k mode because the limits of the heater temperature, we can not grow the atom - smooth epilayer of ain until now so we could not grow better quantum dots which have small diameter and big density but the self - organized quantum dots structures with better quality will be realized successfully if the substrate temperature is increased the thesis study belong to my tutor subject of national nature science foundation ( 69976008 )

    本論文主要論述了在espd - u裝置上,採用電子迴旋共振離子體增強mocvd ( ecr - pamocvd )方,在藍寶石襯底上通過s - k模式自組裝生gan aln量子點結構的生工藝、結果及討論。而重點分析了自組裝生量子點之前的aln外層生工藝,包括襯底清洗、氮化、緩沖層的生和gan 、 aln外層的生;通過能電子衍射、 x射衍射和原子力顯微鏡測試,並且對這些測試結果進行了詳細的比較研究,得出了較優化的工藝條件,生出了晶質較好、表面較平整的aln外層;進而採用s - k模式自組裝生了gan aln量子點結構。由於實驗裝置加熱爐溫度的限制,我們沒有能夠生出原子級平滑的aln外層表面,因而沒能夠生出密度比較大和直徑比較小的量子點。
  4. By the essential control of the initial stage of - material growth, the high - quality crystal films can be obtained. by using mocvd technology, studies of some kinds of methods such as hydrogen - terminated, nitridation, plasma - assisted, growth of two stages and sputtering buffer layers have been conducted. by measuring of xrd, pl, sem and tem, and analysis of spectra of xrd, raman scatting, oa, and pl at different temperatures, we observed that the crystal quality has been improved markedly

    本文利用mocvd技術,採用各種對si襯底處理的方,如氫終止、氮化離子體轟擊方、兩步生、濺射緩沖層進行了試驗與研究,通過x射衍射技術( xrd ) 、光致發光技術( pl ) 、掃描電子顯微術( sem ) 、透射電子顯微術( tem )檢測,並對其x射衍射光譜、拉譜光譜、吸收光譜及不同溫度下的光致發光光譜分析,發現外晶體的生質量得到了明顯提
