抄録: A series of measurements was made on the acoustic properties of fish tissue at high frequencies of ultrasound. The sampled fishes for the measurements are 27 yellow croakers, Pseudosciaena manchurica, and 25 sea breams, Taius tumifrons. After statistic analysis, the following multivariate regression equations for respective acoustic properties of fish tissue were given: yellow croaker; absorption, α1:0.25±0.03dB/cm; sound velocity. Cf:1537±3 m/sec; amplitude reflection coefficient at a plane interface, TR:2.55±0.17%; α1=0.0022(Sex)+0.01386(TL)-0.00037(W)+0.0042(Δρ)+0.0073(Lip)-0.02655(Moist)+1.752, Cf=-0.2702(Sex)+0.82315(TL)-0.04630(W)+0.4843(Δρ)-2.3054(Lip)-6.9766(Moist)+2036.28, TR=0.00001(Sex)+0.00024(TL)-0.00001(W)+0.0008(Δρ)-0.0003(Lip)-0.0012(Moist)+0.0716, sea bream; α1:0.33±0.05 dB/cm; Cf:1550±3m/sec; TR:2.91±0.16%; α1=0.0059(Sex)+0.00645(TL)+0.00011(W)-0.0052(Δρ)-0.0036(Lip)-0.02011(Moist)+1.922, Cf=-0.3863(Sex)-1.25505(TL)+0.03358(W)+0.5996(Δρ)+8.7769(Lip)-3.9741 (Moist)+1847.92, TR=-0.00013(Sex)-0.00038(TL)+0.00001(W)+0.0009(Δρ)-0.0008(Lip)+0.00007(Moist)-0.0160, where, the respective symbols and units are the same as those in Table 1. The multiple correlation coefficients of respective acoustic properties to the other biological and chemical characters of tissue observed were 0.587 to 0.933 and were significant with the risk less than 0.5% in F-test. The author concluded that the above equations are available for the practical use within the experimental range.
