ABSTRACT
When b = 0 3. , the bifurcation diagram of x changing with a is shown as Figure 1. It is found that chaos will yield while a ≥ 1 1. , but there are still some periodic windows. While a ∈[ . , . ]1 390 1 395 , the bifurcation diagram becomes uniform and there are hardly cycle solutions. Figure 2 shows this situation.
