论文摘要
在波动电动力学的非层次论近似中,使用镜面反射模型和金属的非局部介电介电常数,我们在身体相对运动的相对运动中以恒定速度的相对运动获得了颗粒板和板块系统中摩擦力的简单分析表达式。结果表明,在大约1÷10 nm的分离处,对于静止的Au纳米颗粒(或金板),在静止的另一个金板附近移动,耗散力比使用局部Drude介电介电介电特性的情况高2至4个数量级。
In the nonrelativistic approximation of fluctuation electrodynamics, using the specular reflection model and the nonlocal dielectric permittivity of a metal, we obtained simple analytical expressions for the friction forces in the particle-plate and plate-plate systems upon relative motion of the bodies with constant velocity. It is shown that at separations of about 1÷10 nm, for an Au nanoparticle (or a gold plate) moving near another gold plate at rest, the dissipative forces are 2 to 4 orders of magnitude higher than in the case when the local Drude dielectric permittivity is used.
