✦ Synopsis

Evolved gains from YBCO at constant heating ratio were analysed by gas effusion spectra and hy the ma.-.s spectroscopy. Gas effusion spectra at h)wer temperature of both superconductive and non-superconductive YBCO show rather periodic multiple peaks which are similar to spectra of intercalated materials and are attributed to the intercalation of H20. Gas effusions of CO2 are observed not only as a main peak nearly at 700~800°C but "also between 50~500°C. There are .several types of CO2 in YBCO including the intercalation.
