Au-Au2S复合纳米球壳微粒的空腔谐振及参量讨论

Au-Au2S复合纳米球壳微粒（金纳米球壳），是一种新型复合结构的纳米微粒，其结构为纳米级的Au2S介质球外包裹了一层几个纳米厚的黄金球壳。这种复合纳米球壳微粒可以被抽象为球型谐振腔。报道了它的空腔谐振吸收的实验结果，并且运用经典理论结合介观结构特征，讨论了有关Au-Au2S复合纳米球壳微粒空腔谐振吸收的一些重要参量，其中包括谐振吸收波长、品质因数、谐振能量等。另外，还讨论了金球壳的厚度对这些重要参量的影响。     

左Clifford半群的特征与结构

β-MnO2高压相的从头计算模拟

 基于密度泛函理论（DFT），用完全势能线性缀加平面波方法（FPLAPW）计算模拟了MnO₂的同质多相变体（金红石型结构、CaCl₂型结构、黄铁矿型结构），通过计算，预测了β-MnO₂在5 GPa时从金红石型结构转变为CaCl₂型结构，在20 GPa时进一步转变为黄铁矿型结构。另外，还总结和比较了几种金红石型结构二氧化物的压致相变特点，得出第Ⅳ主族元素的金红石型结构氧化物有很好的规律性，发生的相变序列基本一致；并随着金属阳离子半径的增大，发生相变的压力值也相应地递减，各氧化物的体积模量值相应地减小。     

The Design of a 25-Barrel Pellet Injector with Cycle Refrigerator for the HL-2A Device

In the study of nuclear fusion, the conventional fuelling of plasma is edge gas puffing, however many experiments indicated that the fuelling efficiency of gas puffing usually degraded with increase of heat power leading the density profile of plasma control     

The Design for Automation of Pellet-Forming Process in HL-2A Pellet Fueling System

In the ever fusion experiments in SWIP, pellet forming process was carried out through adjusting relative devices by staff member in site, which will make every pellet-forming process slight distinction and will result in pellet difference in shape, size and intensity. In the intervals of HL-2A discharges, staff member have to go site to accomplish the pellet-forming process, this wastes human power and increase the potential danger. So it is necessary to develop a remote control system to perform the pellet-forming process. The control system needs have the features of real-time, reliability and be easy to operate and maintain.
