酚醛树脂固化物的主要结构为苯酚之间通过亚甲基连结的一种三维体型网络，因此在热降解过程中主要表现为酚基和亚甲基的热降解，降解后气态小分子产物很少；而环氧树脂的分子结构是以分子链中含有活泼的环氧基团为其特征，环氧基团可以位于分子链的末端、中间或成环状结构。

Combustion technology. According to the character of CFB and current research, a steady state model of the flow structure and mixing process in the upper dilute zone of a CFB, where variations in flow parameters with height are neglected,揅ontinuous桪ispersion Model? is presented. The model is based on a two梡hase structure, consisting of an upflowing lean suspension and a downflowing particle clusters. On the basis of this model, a numerical simulation calculation model about flow structure and temperature field is established.
