如题，我想问问这张HTEM里面是螺型位错吗，怎么判断的？是否原子相是拍不到螺型位错的，只能看到位错核心有畸变？另附一篇NC加以对比，谢谢各位！[img=HRTEM,690,401]https://ng1.17img.cn/bbsfiles/images/2020/05/202005091145129304_3713_3934985_3.jpg!w690x401.jpg[/img]

下面是NC上发表的一篇论文: Imaging screw dislocations at atomic resolution by aberration-corrected electron optical sectioning
