We adopt the deep learning method CASI-3D (Convolutional Approach to Structure Identification-3D) systemically identify protostellar outflows in 12CO and 13CO observations of nearby molecular clouds, Ophiuchus, Taurus, Perseus Orion. The total outflow masses are 267 Msun, 795 1305 Msun 6332 for Orion, respectively. show mass each cloud is linearly proportional number young stellar objects. esti...

We identify 225 filaments from an H2 column density map constructed using simultaneous 12CO, 13CO and C18O (J = 1–0) observations carried out as a part of the Milky Way Imaging Scroll Painting (MWISP) project.We select 46 long with lengths above 1.2 pc to analyze filament profiles. divide selected into 397 segments calculate profiles for each segment. The symmetries are investigated. proportion...

Several kinds of WC-reinforced coatings were prepared by high-velocity oxygen-fuel spray (HVOF) and electric contact strengthening (ECS), respectively, their corrosion behaviors in 3.5% NaCl solution investigated. The microstructure, element distribution, phase resistance these compared. results showed that, compared with HVOF-sprayed coatings, the ECS-prepared denser lower porosity. Simultaneo...

We present ∼ 3 resolution maps of CO, its isotopologues, and HCN from in the center of Maffei 2. The J=1–0 rotational lines of 12CO, 13CO, C18O and HCN, and the J=2–1 lines of 13CO and C18O were observed with the OVRO and BIMA arrays. The lower opacity CO isotopologues give more reliable constraints on H2 column densities and physical conditions than optically thick 12CO. The J=2–1/1–0 line rat...
