并从理论上指出了这类反应器的一个新的概念:跃迁状态

即热灵敏区间的消失

提出了跃迁条件的数学表达.还讨论了在十分接近热灵敏边界(点火点)的操作条件下

反应系统到达点火的时间(延滞期).

Abstract

This paper deals with the conditions for criticality and other related problems for the continuous-flow stirred tank reactor(CSTR) operating adi-abatically under steady state. A new technique for analyzing the thermally sensitive region of adiabatic CSTR is discussed

and mathematical expressions for two important thermally sen sitive boundaries

ignition and extinction

are given. A new concept on the transition phenomenon or the dis appearance of criticality is pointed out theoretically

and expressions for the conditions of this transition to occur are given. The present paper finally discusses the times-to-ignition for marginally supercritical systems

which are very close to the thermally sensitive boundary of ignition.
