Języki publikacji EN
EN In the present paper, the authors discuss studies carried out for many years by numerous acoustics researchers, dealing particularly with two compounds: benzene and carbon disulphide. They are typical liquids in which acoustic Kneser-type relaxation occurs, caused by an irreversible vibrational-translational (VT) transition. Since magnitudes describing the relaxation process were diverse in many papers, we have undertaken an attempt to clarify these differences and to indicate how to avoid errors resulting from instrumental imperfections and the disregard of considerable measurement errors when investigating velocity dispersion in the hypersonic range.
