摘要
本文在Kolmogorov生态系统的基础上,研究当b_(12)≠0,c_(12)≠1,且内禀增长率为r_1=f+ε(λ_1+λ_2cosωt)r_2=f+ε(λ_1+λ_2cosωt)受到ελ_3cosωt的强迫激励时所产生的浑沌现象。
This paper studied the chaotic phenomenon of the kolmogorov ecologicalsystem on the basis of article[1],When b_(12)≠0,C_(12)≠0,and the intrinsic rateof natural increase is of the form ofr_1=f+ε(λ_1+λ_2cosωt)
r_2=f+ε(λ_1+λ_2cosωt)Which are produced by a forcing oscillation ελ_3cosωt.
