摘要: A first high-resolution survey of molecular cloud cores in the Orion giant is reported. We identified 125 from an analysis spatial and velocity distribution CS (1-0) emission. The are generally elongated along filamentary cloud, axial ratio about 0.5. mass spectrum index -1.6 for M≥50 M ○ .. physical properties compared with those dark clouds reported literature. average radius 0.16 pc, comparable to that
