Abstract

<p><tt>The stability of chemically reacting systems governed by heat balance were analysed. The parameter μ＝1一q/UA, where q </tt><tt>was the derivative of the heat-release rate q with respect to temperature and UA was the heat conductance, was introduced. The system was stable for μ≧0 and unstable for μく0. Thus, μ </tt><tt>was named stability index. It was difiicult to calculate μ directly from q and UA because chemically reacting system in practice continuously changes its states. Therefore, the authors proposed the new method to obtain μ experimentally and simply by slightly perturbing the environmental temperature. △Teo the temperature change of environment, and △Ts that of a system, were related to μ as μ = △Teo/△Ts.</tt><tt> Studies on Potentially Hazardous Reactions IX</tt></p>
