摘要

This paper presents results of the ultrasonic velocity measurements in the temperature range 291-303 K and absorption coefficient measurements in the frequency range 5-43 MHz and temperature range 0.15 ≤ T - T_c ≤ 20 K in the benzonitrile-isooctane critical mixture. Ferrell and Bhattacharjee dynamic scaling theory which predicts a linear dependence between α_c/f~2 and f~(-1.06) was chosen for data analysis. This relation was confirmed by experimental data. The results of acoustic attenuation were also compared with the scaling function of Shiwa-Kawasaki mode-coupling theory, Kroll-Ruhland renormalization-group theory, and Ferrell-Bhattacharjee dynamic scaling theory.
