众所周知施加静水压通常会增强块体材料的声子输运性质.通过采用第一性原理结合玻尔兹曼输运方程计算,该文发现碲化汞这种同时拥有优异热电性能和负热膨胀系数的材料具有反常的压应变热输运行为,即:与传统块体材料不同,碲化汞的晶格热导会随着压应变的增强反而迅速减小.这种反常的热现象主要归因于碲化汞中横波声学声子模式格林爱森常数的增强.该常数的增强也是碲化汞在低温区负热膨胀行为的主要原因.通过与传统块体材料(如金刚石)相比,我们的第一性原理计算还表明,正是由于碲化汞中奇特的电子分布特征导致了其较弱的剪切模量和较强的非简谐声子散射.这些发现为理解负热膨胀材料中声子输运性质与压应变的内在关联提供了新的见解,同时也为增强热电材料能量转换性能提供了新的方案.

Using Green＇s function method, we investigate the spin transport properties of armchair graphene nanoribbons （AG- NRs） under magnetic field and uniaxial strain. Our results show that it is very difficult to transform narrow AGNRs directly from semiconductor to spin gapless semiconductors （SGS） by applying magnetic fields. However, as a uniaxial strain is exerted on the nanoribbons, the AGNRs can transform to SGS by a small magnetic field. The combination mode be- tween magnetic field and uniaxial strain displays a nonmonotonic arch-pattern relationship. In addition, we find that the combination mode is associated with the widths of nanoribbons, which exhibits group behaviors.

【目的】既有振动源强预测公式只适用于普速地铁,无法适用于最高时速160km快速地下线振动源强特性。【方法】对某沿海城市市域快线进行多个断面的振动特性进行了现场实测,通过数据分析研究了车速、隧道埋深、曲线等因素对振动源强的影响。【结果】直(曲)线区段车速90~160km/h,振动源强71~80dB,随着车速的增大振动源强也增大,速度每增加20km/h振动源强增加3.72dB;振动源强随着隧道埋深的增加而减小,隧道埋深每增加10m,振动源强会减小4.9dB;相同情况下,曲线区段(曲线半径1850m)的振动源强大于直线区段的振动源强,值为约7dB。列车投入运营1a后,由于轮轨状态的恶化,振动源强出现增大,且不同列车之间的差异较大,选取某一断面七个月份的监测数据分析得到,运营期稳定后振动源强较为稳定。【结论】快速地下线的振动源强受众多因素影响:与列车速度呈线性正相关、隧道埋深呈线性负相关、曲线处的振动源强大于直线处的、轮轨恶化也会使振动源强增大。
