摘要：

This paper is concerned with the electrophoretic mobility of particles in alternating electric fields. We refer to this mobility as the "dynamic mobility," to distinguish it from the standard electrophoretic mobility, which is defined for static fields. This dynamic mobility can now be measured at frequencies up to 1 MHz with the aid of electroacoustic devices. In this paper we present formulae for calculating the dynamic mobility of spheroidal particles with thin double layers. With the aid of these formulae it should be possible to obtain information on particle charge, size, and shape from electroacoustic measurements on dilute suspensions. © 1992.
