1.The decreasing rate of the flow stress after the first peak decreases and the second peak is much flatter and wider with increase of carbon or manganese content because the addition of carbon or manganese is unfavourable to DEFT and ferrite dynamic recrystallization.
碳、锰含量提高时相变速度减缓 ,铁素体动态再结晶能力减弱 ,分别使得第一峰过后应力软化率减小 ,第二个峰变得宽阔平坦。收藏指正
2.The addition of manganese and aluminum to Pd/C catalyst increases the activity of hydrogenation, the addition of zinc and copper improves the selectivity of THF. When the Pd-M/C catalyst was used for hydrogenation of MA, the reaction pathway was in accord with that hypothesis of Massimo Messori. In the Pd-M1C catalyst system, the most of THF was from form the pathway of MA-GBL- BDO-THF.
探讨了以Pd-M／C为催化剂，MA直接加氢的反应特性，证明在Pd-M／C催化体系中，MA加氢反应基本符合Massimo Messori等人的MA加氢反应网络，但在Pd-M／C催化体系中，THF的主要生成途径是：MA→GBL→BDO→THF。收藏指正
