某卫星运行于深空DRO轨道（Distant Retrograde Orbit，远距离逆行轨道），星上科学载荷软X射线成像望远镜（Soft X-ray Imaging telescope, SXI）由铅玻璃编码板匹配大面积CMOS组成，CMOS需工作在-30℃低温环境。由于SXI视场较大、CMOS功耗较高，且DRO轨道热环境复杂，为保障SXI长期工作的稳定性和可靠性，本文设计了多种热控方案，并采用数值模拟方法建立了热物理模型，对比分析了不同安装方式、有无热管和散热板、以及不同热控涂层措施下的SXI温度场，确定了SXI与卫星舱板隔热安装 ... Per saperne di più
Underground mines that employ the sublevel caving (SLC) method often suffer from significant levels of ore dilution due to the technique of extracting ore through gravity flow. When the ore is blasted and falls into drifts, it creates the drawpoints where Load-Haul-Dump (LHD) vehicles ... Per saperne di più
在新能源汽车中应用GaN表贴器件能够极大提升车载电源的功率密度，提高生产效率，而汽车中高温、高湿、高压的极端应用环境对器件所使用的环氧塑封料提出了更高的防潮耐温要求。本文首先基于菲克扩散定律，采用吸湿试验与COMSOL有限元仿真相结合的办法，对两种常用环氧塑封料的吸湿扩散特征进行了研究，得到相关的湿气扩散特征参数；然后利用COMSOL中的稀物质传递、固体传热、固体力学等模块，对TOLL外形塑封器件在湿热环境中的湿气扩散行为及湿热应力分布进行了模拟；最后基于实际应用，分别对两款环氧塑封料塑封的GaN TOLL器件进行了MSL以及HAST可靠性验证。研究结果表明 ...

声谷赝自旋作为声学系统动量空间中频率极值对应的量子态，为声波调控提供了全新自由度；高阶拓扑绝缘体（HOTIs）拓展了传统体 - 边对应原理，是经典波调控的关键概念。然而，谷声子晶体（VSCs）中的 HOTIs 仅存在于单带隙中，限制了角态的多频选择性，不利于多频声通信器件设计。为此，本研究设计具有 C3 对称性的 “Y 型” 声子晶体，构建出双带 VSC，且其低、高频带隙内的拓扑相变完全一致，最终通过理论与实验实现了双带谷声子晶体中的高阶拓扑态，丰富了 HOTIs 在声学多频调控系统的应用，为多带声学器件设计提供了新路径。 在本研究全流程中 ... Per saperne di più
