解釋
併合試樣法-
From the measurements of cyclic voltammetry and galvanostatic charge / discharge, the composite electrode had higher specific capacitance ( 0. 84f / cm2 ) than pure mwnt array electrode ( 0. 38f / cm2 ) in the same experimental conditions. a kind of linear elementary carbon with the similar structure to carbyne was prepared by a new method. the sample appeared to be winding lines with the diameter of around 0. 2 run in the magnified image of the high resolution transmission electron microscope ( hrtem )
掃描電子顯微鏡表徵結果顯示，聚吡咯比較均勻地附於碳納米管的表面；通過比較復合電極和純mwnts陣列電極在相同條件下的循環伏安和恆電流充放電實驗結果得知，前者的比電容（ 0 . 84f / cm ~ 2 ）明顯高於後者（ 0 . 38f / em ~ 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 。 -
The result showed that the spin coating method was better relatively. the obvious blue shift of pl was found in spectra of the ps / pmma composite prepared with spin coating. compared to the spectra from original ps sample, the luminescence quenching was greatly decreased for ps / pmma composite due to the prevention to ps layer with coated with pmma film and modification of dielectrical penetrability of the medium in quantum threads by the pmma
實驗結果表明，用旋塗法實現的pmma固化后再與多孔硅復合而制得的樣品的結果最好，它與原始的多孔硅樣品相比發光峰發生了藍移而且發光強度下降很小，我們認為pmma層有限的厚度和pmma對多孔硅表面的保護使復合后發光強度下降很小，而且制備的多孔硅pmma復合體系的發光強度幾乎不隨時間而下降。 -

從數字技術的角度描述了未來的鉆探前景，它是基於自動檢測系統、智能專家系統和自動控制系統基礎之上的數字控制體系。 -
In addition, we also explored that : montmorillonite which has been treated by bs - 12 was treated secondly using mma by the method of emulsion reaction and prepared pvc / montmorillonite composite on the way of melt interaction again. by measuring xrd and mechanical properties and observing the section morphology of flexural sample through sem, we found that : after secondly treated, the intension and toughness of pvc / montmorillonite composite were greatly increased. the results indicated that using using montmorillonite can toughen and reinforce pvc effectively, so the study and application of it have a bright prospect
此外，還探討了對經bs - 12初次處理過的蒙脫土，用甲基丙烯酸甲酯採用乳液聚合的方法進行二次處理，再次通過熔融法製成pvc蒙脫土插層復合材料，並通過x ?射線衍射測定和力學性能測試以及掃描電鏡觀察材料的斷面形貌，結果發現，蒙脫土經甲基丙烯酸甲酯通過乳液聚合法二次處理后製成的復合材料與只用bs - 12初次處理的蒙脫土製成的復合材料相比，其強度和韌性得到了明顯改善。
