| Abstract: | In this paper,the measurement of sound velocity of low sound velocity liquid tilled in focusing sphere is present.The dependence relations of sound velocity upon temperature and mixing proportion of liquid had been measured.An empirical equation relating the sound velocity with temperature and mixing proportion of liquid was obtained.Difference between measured and calculated sound velocities was expounded.This paper provides an experimental foundation and theoretical basis for designing and making low sound velocity liquid in the focused liquid-filled sphere. |
