The SBS frequency shift-mixed proportion curves （at T = 21℃） and the SBS frequency shift-temperature curves are obtained. It is expected to get a kind of tunable laser light and coherent sonic radiation by means of stimulated Billouin scattering in mixed liquid medium. 混合液体 受激布里渊散射 体压缩系数 mixed liquid stimulated Billouin scattering coefficient of cubical compression O437.2 1996-03-01 2021-04-01 3
