According to the structures traced by 13 CO spectral lines within 12 CO molecular clouds (MCs), we investigate the contributions of their internal gas motions and relative motions to the total velocity dispersions of 12 CO MCs. Our samples of 2851 12 CO MCs harbor a total of 9556 individual 13 CO st...
