建立了电弧放电中碳纳米管形成的模型。该模型是基于物理性质的电弧放电等离子体的双峰碳速度分布（麦克斯韦和定向）的两个主要组成部分的相互作用占主导地位的纳米管创建过程中的阴极表面附近的区域。种子结构和纳米粒子的形成，终止和重新开始的纳米管生长，和多壳管形成的过程被认为是自洽的。所提出的模型可以定性地解释大多数已知的实验事实有关的纳米管的形成。比较实验已提供和一些后果的模型进行了讨论。
A model for carbon nanotube formation in the are discharge has been developed. The model is based on the physical properties of the are discharge plasma where the interplay of the two major components of the bimodal carbon velocity distribution (Maxwellian and directed) dominates the nanotube creation process in a zone near the cathode surface. The processes of seed structures and nanoparticles formation, termination, and restart of nanotube growth, and multishell tube formation are considered self-consistently. The proposed model can explain qualitatively most of the known experimental facts related to the nanotube formation. Comparison to experiments has been provided and some consequences of the model discussed.
