The thermal desorption spectra of propene and oxygen adsorbed on blue tungsten oxide WO_ (2.90) have been measured by means of flash heating the sample in ultra high vacuum.
Because of the influence of evaporation of water droplet and existence of evaporation wave in the process of flash, there exists minute pressure around the water droplet, even if in the vacuum.
