For the process of the isomerizations, the former is endothermal reaction, the later is exothermic. 前者异构化为吸热反应,后者为放热反应。
The results show that TiN inclusions formed in molten steel during concasting accumulate in mould and react with oxides-SiO 2 and Fe 2O 3 in flux to release nitrogen, and this is an endothermal reaction which promotes solidification of local molten steel to form floater. 结果表明,连铸过程钢水中已形成的TiN在结晶器内聚集,并与保护渣中SiO2和Fe2O3等氧化物反应放出氮气,由于是吸热反应,促使局部钢水冷却凝固形成结鱼悬浮钢块。
Endothermal hydrocarbon fuels ( EHF) is a basic solution on this problem. EHF not only are the necessary propellant for the hypersonic flight, but also can remove heat through physics heat sink and chemical cracking reaction which also yields lower molecular compounds with better ignition performance. 吸热型碳氢燃料是解决问题的基本途径,它既是飞行必不可少的推进剂,也可利用自身物理热沉和化学反应吸收热量,同时生成具有优异点火性能的小分子化合物。
The results of DTA show the endothermal peak of PET disappears with addition of N-100 within PET. This is due to the temperature of the depolymerization reaction of PET shifting to high temperature. DTA的结果表明,加入N-100后最明显的变化为PET的吸热峰消失,这可能是由于解聚反应的温度延后所致。
The results indicate that the decomposition of PET takes place two steps. The first step is the depolymerization of PET with exothermal reaction and the second step is the decomposition of PET with endothermal reaction. 结果表明,PET的分解分为两步,第一步是放热的PET解聚反应;第二步是吸热的PET分解反应。
