摘　　要：参照宁宝林等提供的数学模型,在局部再分法的基础上,本文阐述了一种新的煤粉火焰炉热过程预示数模。引进了“退位追赶”,“局部对称”及“交换面积的互换性”等方法,减少了诱导公式的数目。把诱导公式用于计算机数模降低了操作时间,计算结果是令人满意的。它可用于实际节能及炉子操作中。Reterred to the model contributed b6y Ning Baolin and based on the local dichotomy technique,a new mathematical model for thermal process prediction of pul- verized coal-forging furnace has been developed in this paper.It is necessary to intro- duce a new model by means of the Doolittle matrix decomposition method,the local symmetry method and the exchange ability of direct exchange area due to radiant heat transfer to decrease the number of induced formulae.The induced formulae are appli- cable to the mathematical model of computer.The operation time of computer is de- creased and the results computed are relatively satisfactory.
