Issledovanie koeffitsienta pogloshcheniya i skorosti rasprostraneniya ul"trazvukovykh voln v zhidkosti yavlyaetsya vazhnym sredstvom izucheniya takikh voprosov molekulyarnoy fiziki, kak priroda mezhmolekulyarnykh sil i kinetika molekulyarnykh protsessov, imeyushchikh bol"shoe znachenie dlya dal"neyshego razvitiya molekulyarnoy teorii. Sushchestvuyushchie metody dlya izmereniya akusticheskikh parametrov zhidkikh sred, k kotorym v pervuyu ochered" otnosyatsya metody pretsizionnoy ul"trazvukovoy spektroskopii, uspeshno primenyayutsya v diapazone 0,1 – 200 MGts. Odnako issledovaniya v shirokom diapazone chastot trebuyut ucheta raznoobraznykh effektov, okazyvayushchikh vliyanie na tochnost" opredeleniya akusticheskikh parametrov veshchestv. V rabote rassmatrivaetsya vliyanie nelineynykh i difraktsionnykh effektov pri izmerenii koeffitsienta pogloshcheniya ul"trazvuka v zhidkosti impul"snym i rezonatornym metodami. Monografiya prednaznachena dlya nauchnykh rabotnikov, aspirantov i studentov starshikh kursov, interesuyushchikhsya metodami i zadachami pretsizionnoy ul"trazvukovoy spektroskopii.
