论文摘要
该讲座介绍了金属电导率的基本物理，其温度依赖性及其限制因素。然后，我们将介绍表面电阻的概念，在加速器中与横梁阻抗和RF应用有关，包括与异常皮肤效应有关的概念。表面耐药性将有助于通过辐射和发射率概念建立与体内热交换的联系。然后将引入热导率，讨论其电子和声子交换组件以及相关的限制因素。
This lecture gives an introduction to the basic physics of the electrical conductivity of metals, its temperature dependence and its limiting factors. We will then introduce the concept of surface resistance, of high relevance in accelerators for its link with beam impedance and for RF applications, including notions related to the anomalous skin effect. The surface resistance will help establishing a link to heat exchanges between bodies by radiation, and to the concept of emissivity. Thermal conductivity will then be introduced, discussing both its electron and phonon exchange components, and the relevant limiting factors.
