用气相法制备碳管时，观察到不同寻常的管状碳结构。在低于1300°C的温度下获得了规则的单直径碳管。然而，当温度高于1300℃时，除了普通碳管外，还出现了串珠碳管。这种不寻常的珠状结构的出现和出现被认为与生长温度有关，并用三维成核模型来解释。
Unusual tubular carbon structures were observed when preparing carbon tubes using a vapor phase process. Regular, single-diametered carbon tubes were obtained at temperatures below 1300 °C. However, at temperatures greater than 1300 °C, in addition to regular carbon tubes, beaded carbon tubes appeared. The occurrence and appearance of such unusual beaded structure is thought to be related to the growth temperature, and is explained in terms of a three-dimensional nucleation model.
