摘要：

The form of the asymmetrical velocity profile present in thermal field-flow fractionation is investigated. A theoretical treatment of retention and nonequilibrium peak broadening is given for an exponential concentration profile combined with the asymmetrical velocity profile. The different consequences of the symmetrical and asymmetrical velocity profiles are discussed.
