For the solar nebula the two theoretical models of a low-mass nebula and a high-mass nebula are adopted. It is shown that the calculated profiles typically have double peaks at the velocities of +/- 2-5 km/s, which are separable from ambient emission, and that the profiles vary greatly depending on the inclination angle between the rotation axis of the nebula and the line of sight. The peak flux densities of the profiles are converted into the antenna temperatures of 0.005 to 0.15 K for T Tauri stars in the Taurus complex (140 pc). It is concluded that the gas of other solar nebulae with the radius of about 100 AU can be detected by radio observations of the CO lines until the gas dissipates.
