摘要：

Expressions are derived for retention time and fractionating power F//d for linear and two types of parabolic programmed field decay. The particular case of sedimentation FFF has been considered and plots of both retention time and F//d as functions of particle diameter are generated by computer in order to illustrate the influence of the various experimental parameters. Approximate analytical expressions are derived for retention time and F//d in each case, and from these the means of calculating both the initial field strength and the program time necessary to obtain a desired level of F//d at some particular particle size are obtained.
