Temperature-invariant crystal-glass heat conduction: from meteorites to refra...

The thermal conductivities of crystals and glasses vary strongly and with opposite trends upon heating, decreasing in crystals and increasing in glasses. Here, we show---with...晶体与玻璃态材料的热导率（thermal conductivity）在加热过程中呈现出显著且截然相反的变化规律：晶体的热导率随温度升高而降低，玻璃态材料的热导率则随温度升高而升高。本文中，我们证实——
