Abstract
It is common in thermal explosion theory to neglect the temperature de pendence of thermophysical properties except in the reaction rate. In practice, there are certain circumstances in which this is not suitabl e. This paper examines how the criterion for criticality for a system with uniform temperature (Semenov case) is affected when the heat tran sfer coefficient h is not constant, but depends on temperature. The lo wer boundary at which criticality disappears (transition) is determine d.
