比原封便宜那么一点点而已,没差多少刀。还是买原封省心些

What you see in an image of HRTEM/STEM is not the "movement range" of an atom. Actually, its effects could be neglected. Diffused intensity in diffraction patterns might encode some of those information though. For crystals, potential of atom is radially symmitrical(or close to it) and point spread function of microscope could also be understood as radially symmitrical. Their convolution tends to result into something with Gaussian shape.
