1. 舉例型（推薦）
實例一：The diffraction pattern for the electrodeposited film has seven broad peaks at 11.8°, 16.8°, 26.7°, 35.2°, 39.2° , 46.4° and 55.9°, corresponding to (100), (200), (310),(211), (301), (411), and (521) of β-FeOOH (ICSD 31136), respectively. (Ref.: Zou, S. et al., Chem. Mater. 2015, 27, 8011 – 8020）
句式模板: ... shows/has/exhibits N(特征峰數目) peaks at _, _, _ and _, corresponding to (), (), () and () of __ (JCPDS (或ICSD) ___), respectively.
變型:Wide-angle X-ray diffraction (WAXD) shows broad peaks at _, _, and _°, which arecharacteristic of ... (JCPDS __).
優點：證據確鑿，內容充實，既讓人信服，又可以為下文的其他表征（比如高分辨電鏡中的晶面間距）打好基礎。
適合于：
①XRD 結果或者物質的晶型結構對于文章主體內容有重要價值的時候（例如，材料的晶型是重點考察對象（晶型影響材料性能）時；必須通過 XRD 來對物質組成結構進行定性時）；
②下文其它表征需要和 XRD 結果進行呼應時，比如 HRTEM 圖片中的晶面間距要和 XRD (h,k,l)面進行對應時；
③有多個 XRD 譜圖需要描述時，第一個譜圖的描述宜詳寫，這樣后面的譜圖描述就可以簡略一些，詳略得當。
2. 指派型
實例二： Peaks appearing in the original CdS rods can beindexed to wurtzite CdS (JCPDS __) and those in the fully exchanged rods can be indexed to acanthite(JCPDS __). (Ref. : Robinson, R. et al., Science 2007, 317, 355-358)
句式模板：Peaks appearing in __ can be (well) indexed to __ (JCPDS __).
變型：The pattern for __ has a number of peaks that can be well-indexed to __ (JCPDS __).
優點：言簡意賅，直截了當將譜圖指派給某一物質。
適用于：
①材料組成簡單且比較明確的情況下，XRD 譜圖只是用來區別物質組成時；
②前文已經有對其他 XRD 譜圖進行具體描述時，為了讓文章不重復啰嗦時。
3. 驗證型
實例三：The crystal phase of CuO spheres was further confirmed by X-ray diffraction. (Ref.: Zhu, J. et al., Energy Environ. Sci., 2013, 6, 987-993）
句式模板：The crystal phase of __ was further confirmed by X-ray diffraction.
變型：We further confirmed that thepolycrystalline __ (spheres, nanoparticles, rods) belong to __ by XRD.
優點：句式極其簡單
適用于：XRD 結果作為輔助信息來驗證前文已經較為明確的結果時。
4. 通過峰的尖/寬，有/無，峰強度等來說明物質的結晶性/分散度等
實例一：The diffraction peaks of both BiOI and ZnO were sharp and intense, indicating their highly crystalline nature. No impurity peaks were observed, confirming the high purity of the two products.(Ref.: Jiang, J. et al., J. Phys. Chem. C 2011, 115, 20555 –20564）
句式模板: The diffraction peaks (of __) were sharp and intense, indicating their highly crystalline nature. No impurity peaks were observed, confirming the high purity of the products.
實例二：The X-ray powder diffraction pattern of an electrodeposited catalyst shows broad amorphous features and no peaks indicative of crystalline phases other than the peaks associated with the ITO layer.(Ref.: Kanan, M. and Nocera, D., Science, 2008, 321,1072-1075)
句式模板:The X-ray powder diffraction pattern of __ shows broad amorphous features and no peaks indicative of crystalline phases.
變型：The diffraction pattern of __ has only a very broad peak, indicating the presence of fully amorphous __. This can be ascribed to ... (說明原因)
實例三：No characteristic diffraction peaks of Ni(OH)2 are observed because of its lower loading content and weak crystallization, on the other hand, also implying the good dispersion of the very small Ni(OH)2 clusters on the TiO2 surface. (Yu, J. et al. J. Phys. Chem. C 2011,115, 4953–4958)
句式模板：No characteristic diffraction peaks of __ are observed because of its lower loading content and weak crystallization, on the other hand, also implying the good dispersion of the very small __ clusters on the __ surface.
