利用物镜透镜的球面像差校正技术对多壁碳纳米管进行高分辨透射电子显微镜（HRTEM）研究，为纳米尺度管状材料的观察提供了新的可能性。沿着平行于电子入射方向的图像分辨率的提高使人们能够获得有关管的局部高度的一些信息，并且在200 kV加速电压下，在横向方向上优于0.14 nm，直接确定的可能性提出了碳管的手性和观察碳原子更精细的原子结构（例如“六边形”结构）的建议。球差校正的高分辨透射电镜为纳米管状材料的结构研究开辟了一个新的阶段。
High-resolution transmission electron microscopy (HRTEM) of multi-wall carbon nanotubes using a spherical aberration correction of the objective lens has shown a new possibility for the observation of nanometre-sized tubular materials. Improvement of the image resolution along a direction parallel to that of electron incidence enables one to obtain some information on the local height of the tubes, and in lateral directions better than 0.14 nm at 200 kV accelerating voltage, the possibility of direct determination of the chirality of the tubes and the observation of finer atomic structures of carbon atoms such as ‘hexagon’ ones is suggested. Spherical aberration corrected HRTEM begins a new stage of the structural study of nano-tubular materials.
