摘要：

From an analysis of the.SS Cygni light curve, we have recently shown (Hempelmann & Kurths 1990) that the rate of mass transfer, M(T), from the secondary star to the white dwarf primary is inversely correlated with the outburst cycle, t(c). This has been criticized as being of a trivial nature by Cannizzo & Mattei (1992). We demonstrate the nontrivial character of our finding by means of a gedankenexperiment which is based on the static outburst parameters observed. We show in this experiment that a positive M(T)-t(c) correlation is possible. The negative correlation found by Hempelmann & Kurths (1990) is a consequence of the dynamics of small and strong outbursts.
