各位虫友，本人做了一个alpha-Fe2O3负载的Pd催化剂的HRTEM（见图）。 我对TEM不熟悉，现请求帮助：（1）可以帮我计算以下晶格间距吗（图中我试着标示了一下，我画得正确与否）？

使用高分辨率透射电子显微镜 (HRTEM) 观察和组合，报告了一种新的调制结构，由铁箔热氧化形成的 α-Fe2O3 纳米线 (NW) 中的周期性 (1120) 堆垛层错 (SFs) 组成。 HRTEM 图像模拟。 调制结构的周期性为 1.53 nm，是 (3300) 面间距的十倍，可以通过每十个 (3300) 面与 (1120) 面的面间距的 1/2 位移来描述。 提出了 Fe2O3 结构的原子模型来模拟调制结构。 HRTEM 模拟结果证实 α-Fe2O3 NWs 中的调制结构是由 SFs 引起的。 使用高分辨率透射电子显微镜 (HRTEM) 观察和 …

通过x射线衍射（xrd）、x射线光电子能谱（xps）、扫描电子显微镜（sem）、透射电子显微镜（tem）和高分辨率透射电子显微镜（hrtem）对所获得的产物进行表征。

high resolution transmission electron microscopy (HRTEM) techniques. HRTEM study shows well resolved (110) fringes corresponding to α-Fe2O3, and selected area diffraction pattern (SADP) confirms the crystalline nature of α-Fe2O3 polyhedral nanoparticles. It is observed that polyhedral formation of α-Fe2O3 nano crystals depends upon annealing
