论文摘要
我们研究了获得具有功能分级的Si-GE合金的热二极管的可能性。考虑了带有可变部分的电线。引入了使电线的热导率与物种含量和电线直径的函数的公式后，给出了数值和分析结果，以支持在此处考虑的具有具有特征的热二极管的不切实际性。但是，本研究为进一步的概括开辟了道路，可以给出适用的有希望的结果。
We investigate the possibility to obtain a thermal diode with functionally graded Si-Ge alloys. A wire with variable section is considered. After the introduction of a formula giving the thermal conductivity of the wire as a function of the species content and of the diameter of the wire, numerical and analytical results are presented supporting the impracticability to get a thermal diode with the characteristics here considered. However, the present study opens the way to further generalisations amenable to give applicative promising results.
