化学反应器设计中的分叉(Bifurcation)及浑沌(Chaos)问题

Bifurcation and Chaos in the Design of Chemical Reactors

论述了从70年代中期以后在反应工程及控制工程中对分叉现象及浑沌现象所作的研究,提出了研究分叉现象的主要方法,这些方法对复杂反应系统的稳定性设计是极为重要的。

Nonlinear problems in chemical dynamics have fascinated engineers and scientists since 1950s. Notable among such problems are those of stabilities of reaction and control system design. Attempts to elaborate on the dynamic behavior and reach the optimal performance led to the studies of bifurcation and chaos: the highly nonlinear characteristics on the verge of instability. The studies on bifurcation and chaos problems have been, since the middle of 1970s, carried out in the fields of reaction and control engineering. Some of the approaches demonstrated in bifurcation theory are extremely important to the stability design of reaction: dissipative system, fluid bed reactor, polymerization reaction system, and corresponding control systems.
