  1. The results from x - ray diffraction demonstrated that pp / mmtome was a fully intercalated nanocomposite, pp / mmtom and pp / ommt were partly intercalated nanocomposites, but the intercalation effect of pp / mmtom nanocomposite was better ; the crystallization characteristics of pure pp and pp / mmt nanocomposites were investigated by dsc, waxd and pom. the result of these testing showed that mmt nano - layers acted as nucleating agents for the crystallization of pp, the addition of mmt had effect on the crystallization process, leading the increasing of crystallization temperature crystallization rate and crystallinity, but also the dimension of spherulite reduced. but the formation of pp crystal did n ' t change, the formation of pp crystal in three pp / mmt nanocomposites and pure pp were a - form on the whole ; influences of three sorts of mmt on mechanical properties of pp / mmt nanocomposites were studied, as a result, the addition of mmt comprehensively improved mechanical properties of pp : notched impact strength, tensile strength and flexural properties were all increasing, but the extent of increasing were n ' t large

    通過xrd分析比較這三種pp mmt納米復合材料微觀結構得到, pp mmt _ ( ome )屬于完全插層, pp mmt _ ( om )與pp ommt的插層程度相近,但是pp mmt _ ( om )相對較好;通過對純pp和三種pp mmt納米復合材料的結晶性能研究發現,蒙脫土納米片層對pp結晶產生明顯的異相成核作用,結晶能力增強,使pp的結晶溫度和結晶速率提高,結晶度增加,球晶晶粒細化,但是沒有改變pp的結晶形態,三種pp mmt納米復合材料的結晶形態都屬于晶;通過對pp mmt納米復合材料的力學性能測試得知,蒙脫土的加入全面提高了pp的力學性能,缺口沖擊強度、拉伸強度和彎曲性能都有一定程度的提高,浙江{ _業大學碩十學位論文摘要但是提高幅度都不是很大,不過ommt 、 mmtom和mmtc ) me三種蒙脫土對pp力學性能有著不同的改性作用,其中pp / mmtom最好, pp月邊mto崛次之, pp / ommt最低,這種情況主要是由蒙脫土對pp結晶性能的影響和蒙脫土的納米改性作用造成的。
  2. Process capability index ( pci ) is also an important method to measure and improve quality, which has play a key role in assuring quality evidence, lowering cost and raising customer satisfaction indexes ( csi ). this paper studies the applications of pci and control chart from the actual viewpoint, and discusses the applications of the probability a, ( 3 of type i, ii error of the control chart, the detecting power and pci based on x control chart. in addition we explore the relationship between qlf and pci, put forward the concepts of relative loss and loss extent, adopt the linear plan to optimize pci and decide the best loss extent of each process. an example is given

    )控制圖為例,討論了控制圖的兩類錯誤、檢出力與過程能力指數在實際中的應用;重要的是討論了質量損失與過程能力指數之間的關系,提出了相對質量損失、損失度等概念;研究了多道工序相對質量損失、損失度對總質量損失的影響,並從質量損失的角度出發,採用線性規劃的方法,優化多工序的過程能力指數,確定各道工序的最佳損失度,實證討論了這種關系,同時可以利用這種關系對供應商進行評價,給出了從全局的、動態的角度選擇供應商的方法,為上下游企業間的配合、監督及共同進步提供了理論基礎和實現途徑。
  3. These conclusions will be valuable for the non - destructive testing techniques based on the vibrothermography method to some extent. compared with other conventional detection method ( such as ultrasonic scanning, x - ray radiography, and acoustic emission, etc. ), the vibrothermography method presented in 1980s is rapid, safe, non - destructive and applicable to the structures " global detection

    本文所研究的振動紅外熱像法是上世紀八十年代以來出現的一種無損檢測方法,與其它傳統的檢測方法(如超聲波法、射線照相法、聲發射法等)相比,具有快速、安全、無損和可對整體結構進行全場檢測的優點。
  4. Extent and location of x - ray photographs inspection to be in accordance with the classification rules

    外部的和特定區域的x光照片檢驗應依照船級社的規則。
  5. The specimens of uranium flat were heated in air, oxygen or low pressure, to investigate the formation of uo2 + x and u3o8 on the surface layer of specimens. the processes of oxidation to uo2 + x and u3o8 were analyzed by xrd to determine the extent of surface layer oxidation and the structure of oxidations. the xrd patterns were fitted by rietveld method to refine the structure of different phases and to calculate quantificationally

    對金屬鈾表層在大氣環境中的氧化情況進行分析研究,結果表明:所有溫度條件下,金屬鈾的氧化都是在表層形成一定厚度的uo _ ( 2 + x ) ,只有在較高的溫度條件下(如300 )氧化物才會進一步轉化為u _ 3o _ 8 。
