由Drude模型描述的金属和具有有限直流电导率的金属对热力学第三定律的违反是Casimir效应领域中最有趣的问题之一。它表现为温度为零时熵的不为零。我们回顾了平面表面的相关计算，并计算了平面前的球的相应贡献。在此几何中，这些与平行平面的显示方式大致相同。我们得出结论，第三定律的违反与平面的无限大无关。
The violation of the third law of thermodynamics for metals described by the Drude model and for dielectrics with finite dc conductivity is one of the most interesting problems in the field of the Casimir effect. It manifests itself as a nonvanishing of the entropy for vanishing temperature. We review the relevant calculations for plane surfaces and calculate the corresponding contributions for a ball in front of a plane. In this geometry, these appear in much the same way as for parallel planes. We conclude that the violation of the 3rd law is not related to the infinite size of the planes.
