　　我們使用自洽場近似來研究一對手椅狀碳微管的低頻磁電子激發。碳微管間的庫侖交互作用會產生同向與反向的電漿子模式。我們仔細地研究電漿子的存在與否、強度、頻率、以及群速度。它們主要被轉換動量、管子之間的距離、和磁場的強度與方向所支配。

　　The low-frequency magnetoelectronic excitations in a pair of　armchair carbon nanotubes are studied within the self-consistent-field　approach. The intertube Coulomb interactions would induce　the coherent and incoherent plasmon modes. Their existence, intensity,　frequency, and group velocity are investigated in detail. They are　dominated by the transferred momentum,the intertube distance; the magnitude and the direction of the magnetic field.
