We used the 13.7 m millimeter-wave telescope of the Qinghai Station of Purple Mountain Observatory at Delingha to carry out simultaneous mapping observations in the 12CO(J = 1 − 0), 13CO(J = 1 − 0) and CO18 (J = 1 − 0) lines towards 11 isolated

A spherical and large-velocity-gradient model is adopted for the theoretical calculations of NGC 7027, AFGL 2688 and IRC+10216, whose emissions of CO far-infrared lines are comparatively strong. The statistical equilibrium calculations cover 107 ener
