Query: The developing structure of dynamical systems   In order to investigate the evolutionary process of many deterministic
Dynamical systems with unfixed parameter, a set of dynamical models with
parameter changing continuously and the accumulation of this change might be
large is introduced and discussed. The boundary crises and the period-doubling
bifurcations are found suppressed and scaling properties for these phenomena
are exploited. Due to this suppression, the period-doubling bifurcations seem
no longer continuous. We further discuss the possible applications of these
models.
