Abstract: 

Molecular clouds (MCs) are the fundamental components within galaxies and also the sites of star formation. Understanding the dynamic evolution of MCs is crucial for understanding how large-scale gas gradually accumulates into the stellar systems. While several scenarios of the formation and evolution of MCs have been proposed, observational supports for these scenarios are still insufficient. Using a large sample of MCs from the Milky Way Imaging Scroll Painting (MWISP) CO survey, we conducted a systematic analysis of 13CO structures within MCs. We focus on their content, spatial distribution, and relative motion. Upon these derived statics, we try to provide a general picture on the build-up process of MCs.
