We report on the research of the stability of partitioned (bamboo-like) carbon nanotubes with different diameters. The stability of the partitioned carbon nanotubes of the smallest diameter were determined by the tight-binding method. For the prediction of the destruction regions of the bamboo-like nanotubes atomic framework subjected to strain the new original method of the calculation of the local stress of atomic network was developed. Using this method it was shown that partitioned carbon nanotubes with a diameter of 2.02 nm are stable. These partitioned carbon nanotubes with chirality (15,15) are the most stable partitioned carbon nanotubes with the smallest diameter.
我们报告了不同直径的分段（竹状）碳纳米管稳定性的研究。通过紧束缚方法确定了最小直径的分段碳纳米管的稳定性。为了预测在应变作用下竹状纳米管原子框架的破坏区域，开发了一种计算原子网络局部应力的新原始方法。使用该方法表明，直径为 2.02nm 的分段碳纳米管是稳定的。这些具有手性（15,15）的分段碳纳米管是具有最小直径的最稳定的分段碳纳米管。
