(1)Investigation of technical requirement to be met in order to achieve all solid substation is conducted.(2)A centrifugal force can be applied to fabricate the permittivity functionally graded materials from alumina/epoxy mixture. SEM images show that both the number density and size of alumina fillers are continuously graded.(3)Movement of an alumina particle is numerically and successfully simulated and, based on the numerical results, the way how the centrifugal conditions have influence on the centrifugal process.(4)Electrical properties of the fabricated alumina/epoxy resin such as the permittivity profiles and electrical discharge characteristics are experimentally examined, and the advantage of FGM on those properties are illustrated.(5)It is numerically demonstrated that a ultrasonic wave can be used to fabricate thin FGM from alumina/epoxy mixture.

（1）研究实现全固态变电站所需满足的技术要求。(2)A可以施加离心力以由氧化铝/环氧树脂混合物制造介电常数功能梯度材料。SEM图像显示氧化铝填料的数密度和尺寸都是连续分级的。（3）成功地对氧化铝颗粒的运动进行了数值模拟，并在此基础上分析了离心条件对离心过程的影响。（4）对所制备的氧化铝/环氧树脂复合材料的介电特性、放电特性等进行了实验研究，并分析了功能梯度材料在这些方面的优势。(5)It数值模拟表明，超声波可以用来制造薄的功能梯度材料从氧化铝/环氧树脂混合物。
