2(deg) 图5 Si 样品 XRD 数据图谱 (二)用 sinθ2 比值法确定晶面指数和晶格结构 根据公式: 2dsinθ = λ 立方晶系:dhkl = a h 2 +k 2 +l 2 两式联立得: sin θ2 hkl = 4a 2 (h2 + k 2 + l2 ) λ2 所以: sinθ1: sinθ2: sinθ3: …… = (h12+k12+l12): (h22+k22+...
The VR fractions showed a broad peak around 20 deg C with sharp peaks around 22 and 24 deg which are ascribed to aliphatic chain entanglement and ordered packing of n-paraffins, respectively. They also showed a shoulder around 26 deg which is ascribed to aromatic ring stacking interactions. ...

3、设定仪器参数:采用θ~2θ联动,1deg/min,扫描范围为26°~116°,设定完参数后开始扫描。 4、试验完之后,关闭XRD电源,过一段时间,再关闭循环水冷却系统。六、实验数据 测试完毕后,可将样品测试数据存入磁盘供随时调出处理。原始数据需经过曲线平滑,Ka2扣除,谱峰寻找等数据处理步骤,最后打印出待分析试样衍射曲线...
