A one-dimensional two-parameter map whose behavior on the plane of con
trol parameters qualitatively reproduces the dynamics of a flow system
- an rf oscillator describable by a system of three ordinary differen
tial equations. It is it is shown that that the behavior of the map la
rgely coincides with that of the flow system and is also similar to th
e results of a previous experiment on the rf oscillator. (C) 1998 Amer
