在最近的一篇论文中[Phys.Rev.A 78,020101(R)(2008年)]，Kim等人。已经报道了球与板之间静电相互作用的标度律中的一个大反常，这是在校准他们的Casimir力设置时观察到的。在这里，我们通过实验证明，这种行为并不普遍。使用我们的设置获得的静电校准遵循从基本静电论点预期的定标定律，即使当一个人必须施加使力最小的静电电压(通常归因于接触电位)取决于表面之间的间隔时。
In a recent paper [Phys. Rev. A 78, 020101(R) (2008)], Kim et al. have reported a large anomaly in the scaling law of the electrostatic interaction between a sphere and a plate, which was observed during the calibration of their Casimir force setup. Here we experimentally demonstrate that this behavior is not universal. Electrostatic calibrations obtained with our setup follow the scaling law expected from elementary electrostatic arguments, even when the electrostatic voltage that one must apply to minimize the force (typically ascribed to contact potentials) depends on the separation between the surfaces.
