• 中文摘要： 圓柱、平板及球狀三種幾何形狀高能物質的臨界.delta./sub cr/值與自發點火臨界溫度 T/sub c/的經驗式可表示為.delta./sub cr/=a/sub 0/+ a/sub 1/exp(-.alpha.E/RT/sub c/)+a/sub 2/exp(-.gamma.E/RT/sub c/)及E/RT/ sub c/=c/sub 1/+c/sub 2/ln〔 RQAr/sub 0//sup 2//E.lambda.〕,這些經驗式經由數值計算及曲線回歸的方法求解Frank-Kamenetskii所定義之熱爆炸穩態理論的微分方程式而得,使用這些方程式可直接計算出物質爆炸時Frank- Kamenetskii之臨界參數及自發點火臨界溫度而無須藉由疊代方法,經與實驗數據比較發現,此計算結果更優於文獻上其他的方法,且計算過程較為簡便。
• 英文摘要： The explicit formulae of criticality .delta./sub cr/ and self-ignition temperature T/sub c/ in the geometries of infinite cylinder, infinite slab and sphere were expressed as .delta./sub cr/=a/sub 0/+ a/sub 1/exp(-.alpha.E/RT/sub c/)+a/sub 2/exp(-.gamma.E/RT/sub c/) and E/RT/sub c/=c/sub 1/+c/sub 2/ln [ RQAr/sub 0//sup 2//E.lambda. ] . These formulae were set up by means of the numerical calculation and curve fitting method to solve the differential equation. This equation is defined by the Frank-Kamenetskii's stationary theory of thermal explosion. Calculations of Frank-Kamenetskii's critical parameters and self-ignition temperature using these formulae are straightforward without any iterations. After comparing with known experimental data, we found that the calculated results and procedure are better and easier than the way from other investigators.
