Both SiO and H_2_O masers were detected from 62 sources with a detection rate of 40.8%. The SiO-only maser emission without H_2_O maser detection was detected from 27 sources, while the H_2_O-only maser without SiO maser detection was detected from 22 sources. Therefore, the overall SiO maser emission was detected from 89 sources, resulting in a detection rate of 58.6%. We have identified 70 new detections of the SiO maser emission. For both H_2_O and SiO maser detected sources, the peak and integrated antenna temperatures of SiO masers are stronger than those of H_2_O masers in both Mira variables and OH/IR stars and the relative intensity ratios of H_2_O to SiO masers in OH/IR stars are larger than those in Mira variables. In addition, distributions of 152 observed sources were investigated in the IRAS two-color diagram.2013AJ....145...22Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/145/22CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/vsx : AAVSO International Variable Star Index VSX (Watson+, 2006-2014)B/gcvs : General Catalogue of Variable Stars (Samus+ 2007-2013)III/227 : General Catalog of galactic Carbon stars, 3d Ed.
