为探究稀土离子掺杂对Ca_(3)Ti_(2)O_(7)物理性能的调控,采用固相反应法制备了Sm^(3+)掺杂的(Ca_(1-x)Sm_(x))_(3)Ti_(2)O_(7)(x=0,0.02,0.04)陶瓷样品,通过XRD、XPS、紫外-可见光吸收光谱以及第一性原理计算等方法对样品的晶体结构、光学性能、电学性能和磁学性能进行分析.结果表明:随着Sm^(3+)含量的增加,(Ca_(1-x)Sm_(x))_(3)Ti_(2)O_(7)的晶胞参数逐渐增大.Sm^(3+)掺杂导致氧空位减少,因此样品的漏电流随着Sm^(3+)掺杂量的增加而减小.同时,随着Sm^(3+)掺杂量的增加,样品的光学带隙呈现增大趋势.此外,第一性原理研究表明,Sm^(3+)掺杂可在体系中诱导出磁性能,进一步丰富了该材料的物理性能.

氨气燃烧面临着氮氧化物排放高、燃烧稳定性差等问题，而分级燃烧概念是解决上述问题的途径之一，但其中复杂的燃烧特性尚不明确。为此，对一个自主设计的轴向空气分级氨气-甲烷湍流燃烧装置开展了详细的实验测量和大涡模拟研究。以氨/甲烷的混合物为燃料，首级当量比保持为1.2，总当量比在0.4-0.9之间改变，通过实验测量获得了一氧化氮（NO）随总当量比的变化特性，采用大涡模拟结合动态火焰增厚模型对3个燃烧状态进行了计算分析，计算结果与实验数据吻合良好。研究表明：随着总当量比的减小，NO排放呈增加的趋势；燃烧室内存在两种燃烧模式，上游是金黄色的含氨燃气富燃预混火焰，下游则是淡蓝色的氢气-空气扩散火焰为主；一级燃烧室中，NO排放主要受OH影响，而二级燃烧室中NO生成受OH影响变小。

介绍了一种开发AA6063铝合金再结晶模型的创新方法。该方法结合了基于回归分析的材料常数测定技术，并引入了评估晶粒尺寸演变的新方程。该方法的校准和验证结合了从3种AA6063铝合金型材的挤压实验中获得的显微组织数据和使用Qform Extrusion UK有限元代码模拟的结果。结果表明，显微组织演化的实验结果与数值模拟的预测结果相吻合。该方法准确模拟了动态再结晶和静态再结晶后晶粒尺寸随不同工业参数变化的趋势，在几乎整个抽样计算中，误差都小于25%。
