摘要
This review gives a short introduction into the principles of ultrasonic measurement techniques for liquids,using cavity resonators.Guidelines for the resonator design in broad-band ultrasonic spectroscopy as well as in high-resolution single-frequency or narrow-band applications are presented.Deviations of the field configuration in real cells from that in an ideal resonator are discussed and relations for the mode spectrum of cavity fields are given.Recent resonator measurement procedures and methods of data evaluation are mentioned briefly.Some examples of measurements show the extended usability of ultrasonic resonator techniques in basic science and in a wide range of applications for materials characterization,in manufacturing processes,as well as in control routines.
This review gives a short introduction into the principles of ultrasonic measurement techniques for liquids, using cavity resonators. Guidelines for the resonator design in broad-band ultrasonic stxctroscopy as well as in high-resolution single-frequncy or narrowband applications are presented. Deviations of the field configuration in real cells frtxn that in an ideal resonator are discussed and relations for the mode spectrum of cavity fields are given. Recent resonator measurement procedures and methods of data evaluation are mentioned briefly. Some examples of measurements show the extended usability of ultrasonic resonator techniques in basic science and in a wide range of applications for rrkaterials characterization, in manufacturing processes, as well as in control routines.
