摘要
为探讨有机－无机烧结合金的形成机理，应用微量热重分析仪测定了不同环境条件下液体酚醛和沥青的热失重情况，并应用“表观活化能谱”的新概念详细分析了其热解机理，揭示了其变化的内在实质，为有机－无机高分子烧结合金的研究提供了可靠的理论依据．
The thermal degradation of the phenolic aldehyde and coal pitch in different environment was studied by thermal degradation. The mechanism of thermal degradation was analyzed detailly by using the new concept of "apparent activation energy spectrum",and the internal feature was revealed. A reliable theoretical basis was provided for the study of the formation mechanism of organic-inorganic macromolecule sintered alloy.
