摘　　要：用超声波处理水溶液中的高序石墨固体 ,借助于高分辨透射电子显微镜和电子衍射 ,不但看到了与电弧放电和激光烧蚀产物相似的碳纳米多面体和纳米管 ,而且还发现了一种罕见的实心碳纳米球 .对这种由扰动石墨晶格组成物的形成过程给出一种可能的模型解释 .After the high oriented plane graphite has been treated by ultrasonic wave in water, by using high resolution transmission electron microscope and electron diffraction, we have found that carbon nanopolyhedron and carbon nanotube, which are similar to those found by means of arc discharge and laser ablation, have been produced. More importantly, we have also found a kind of novel carbon nano solid ball which consists of disturbed crystal lattice lines. In addition, we put forward a possible model to explain the growth process of these nanostructures.
