摘要：
我们研究了利用功能梯度Si-Ge合金制备热二极管的可能性，研究对象为变截面线结构。在引入线的热导率随组分含量与线直径变化的公式后，我们给出了数值与解析结果，证明具备本文所考虑特性的热二极管不具备可行性。不过，本研究为后续有望产出应用价值成果的推广研究开辟了道路。
英文摘要：
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.
