Abstract (in Japanese) (See Japanese page) 
(in English) Ultrasonic microspectroscopy technology is applied to characterization of synthetic silica glasses. Acoustic properties (longitudinal and shear velocities, leaky surface acoustic wave velocity, and density), coefficient of thermal expansion, fictive temperature, and chlorine concentration were measured, and the relationships among their properties were discussed. The variations in acoustic properties due to fictive temperatures and chlorine concentrations were quantitatively obtained. Longitudinal velocity has highest sensitivities of 5.99 (m/s)/°C and –164 wtppm/(m/s) and resolutions of 0.6°C and 16 wtppm for both fictive temperature and chlorine concentration, respectively. The variations in acoustic velocities due to fictive temperature and chlorine concentration are mainly caused by the variations of the elastic constants.
