  1. The rietveld method is a process of refinement in terms of a postulated method.

    Rietveld方法是一個取決于假設模型的精化過程。
  2. Moreover, we got the accurate figure of the crystal structure of ti stone through the rietveld method

    還通過rieweld方法對鈦寶石晶體的結構進行了精確的表徵。
  3. Through the rietveld method of whole pattern fitting of the three parts, we found that the distribution of ti ions in the crystal increase from the bottom to the top

    通過rietveld方法對鈦寶石晶體三個部位進行全譜擬合，晶體中鈦離子分佈是從晶體的底部至晶體的頂部逐漸增加的。
  4. The xrd dates were refined by rietveld method of whole pattern fitting by using the computer progress of dbws - 9411, and then the exact crystal structures were got

    用計算機程序dbws - 9411 ，對yag的粉末衍射數據進行了rietveld全譜圖擬合，得到了準確的物相結構。
  5. We continued to use the rietveld method of whole pattern fitting of the x - ray powder diffraction data, then found that additive mgo may bring the crystal thinning of al2o3 ceramics, which can improve many properties of ceramic materials. meanwhile, we discussed the operation mechanism of the crystal thinning

    然後對其x射線粉末衍射數據進行rietveld全譜擬合，得知mgo的添加可以細化al _ 2o _ 3陶瓷的晶粒，晶粒的細化可以提高陶瓷材料的許多性能，同時對其細化晶粒的作用機理進行了討論。
  6. The structure of triuranuim octaoxide ( u3o8 ) and the oxidation of uranium metal were studied by x - ray diffraction ( xrd ) and rietveld method in different partial pressure of oxygen and temperatures

    本論文利用x射線衍射（ xrd ）並結合rietveld方法較系統地對金屬鈾和八氧化三鈾（ u _ 3o _ 8 ）在不同溫度、壓力條件下的表層氧化情況和結構變化進行了分析研究。
  7. The rietveld method is a process of refinement in terms of a postulated method

    Rietveld方法是一個取決于假設模型的精化過程。
  8. 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 。
