It is hard to get the satisfied mechanism model in the deasphalting process of residue oil for complicated influential factors and intricate reactive mechanism.
渣油裂解反应中，影响沥青产率的因素多，反应机理十分复杂，难以建立准确的机理模型。
Different mechanism may account for the rheological properties development during curing, and the oxidation effect plays a negligible role in the rheological development of hard bitumen emulsion residue.
不同乳化沥青残留物养护过程中的流变性能发展机理并不相同，氧化作用对本研究中硬质乳化沥青残留物流变性能发展的影响效果不明显。
The results indicate that Han curve of this hard bitumen residue were not temperature dependent which means no phase separation occurs during the process; therefore, time temperature superposition principle is feasible.
结果表明：硬质乳化沥青的Han曲线在测试频率和温度范围内不存在温度依赖性且未出现相分离的过程，因此时温等效原则的应用是可行的。
