Abstract

The specific features of hypersound propagation in aqueous solutions of nonelectrolytes in dependence of frequency and temperature have been investigated using Brillouin spectroscopy. Nontrivial temperature behavior of hypersound at small Brillouin scattering angles is observed in the vicinity of solution singularity. The temperature dependences of hypersonic velocity in aqueous solutions of methylpyridines and acetone at different frequencies have been analyzed.

非电解质水溶液中超音的频率行为

摘要

超音波在非电解质水溶液中随频率和温度变化的特定特征已经使用布里渊光谱法进行了研究。在溶液奇点附近观察到超音速在小布里渊散射角下的非平凡温度行为。分析了不同频率下甲基吡啶和丙酮水溶液中高超声速的温度依赖性。
