摘要:

利用GNＧ２型高能球磨机研磨了Y２O３粉末晶体,用BT-１６００图像颗粒分析仪对研磨时间为０h和２０h的两份样品进行了分析．室温条件下,利用X射线衍射实验检测了晶体结构的变化,并且利用RIETANＧ２０００程序进行了晶体结构精修得到了原子热振动的大小．运用MEM 解析方法实现了２D(平面)和３D(立体)的等高电子密度分布的可视化.

Abstract:

Using GN-２ high energy ball mill grinding Y２O３ crystal,the two samples were analyzed byBT-１６００image particle analyzer which grinding time of ０h and２０h．The change of crystal structure was tested by X-ray diffraction at room temperature．The crystal structure was analyzed by RIETAN-２０００program and we obtained the size of atomic thermal vibration ．The visualization of ２D (plane) and ３D (cubic) was realized by MEM analysis method．

Key words: Crystal structure XRD MEM analysis Atomic thermal vibration
