在恒定的加热速率下,可以对方程7进行积分,以获得作为温度的函数的反应程度。所得积分是指数积分,不能得到简单的表达式。Murray和白色(14)用分部逐次积分法得到了令人满意的近似。一个快速收敛的系列的结果,使几乎没有错误的所有条款后,第二个可能会下降。使用Murray和白色的表达式,等式7的积分得到n(1/1 =!+(1)(14)
Equation 7 can be integrated, assum-ing a constant heating rate, to obtain the extent of reaction as a function of temperature. The resulting integral is an exponential integral and a simple expression can not be obtained. A satisfactory approximation was ob-tained by Murray and White (14) by successive integration by parts. A rap-idly converging series results, so that with little error all terms after the second may be dropped. Using Murray and White’s expression, integration of Equation 7 results in n (lzV1=!+(»-1)(14)
