汽油抗爆性能预测新方法探索

, 1997
本文在汽油生产质量控制方面进行了一些基础研究。文中采用基团组成与拓扑指数相结合的方法研究了烃类辛烷值的构效关系。提出了以烃类过氧化物的生成和分解这一模型化反应描述烃类燃烧反应的方法，并以烃类燃烧反应中某一时刻生成的烃类过氧化物的浓度标度其抗爆性能，建立了描述烃类抗爆性能的氧化反应机理模型。应用该模型分别对烷烃化合物和实际汽油样品的抗爆性能进行了关联和预测研究，结果表明其计算值与文献值或试验值具有良好的一致性。因此，本文提出的方法用于建立汽油燃料抗爆性能的预测模型是合理可行的 ...

Zr对2:17型SmCo磁体力学各向异性的影响研究

, 2017
2:17型SmCo磁体因其较高的居里温度及优异的温度稳定性成为了高温应用领域的首选材料,但是差的力学强度限制了其应用与发展[1,2]。目前主要采用添加晶界相的方法改善力学强度[3],但Zr含量对微观结构的影响导致力学性能差异的机理尚不清楚。本文采用粉末冶金工艺制备Sm(Co_(bal)Fe_(0.09)Cu_(0.09)Zr_x)7.68(x=0.020,0.025,0.030,0.035)磁体,研究Zr含量对力学性能的影响并对其机理进行分析。抗弯强度分析结果如图1所示,Sm_2Co_(17 ...
