摘要
利用微分系统的定性理论研究了一个连续发酵动力系统的多次非线性振荡问题,探讨和估计了存在多个极限环的条件.是对文献[3,12]所提出发酵模型的深化,并对发酵产物与基质浓度的非线性函数关系做了进一步的深入研究.
The nonlinear oscillations in a continuous fermentation model with variable yield are studied by means of the qualitative theory of a differential system. The conditions of the existence of multiple limit cycles are discussed. The work is a generalization of the one done by [3,12], which is useful in a further study of the nonlinear oscillations in continuous fermentation.
