摘　　要：Casimir效应是一个可观测的宏观量子效应.研究了各向异性材料的填充比例因子f2对Casimir力大小和方向的影响.在f2=0.000 1时,由材料的介电常数和磁导率随着频率的变化曲线,得到Drude背景会对Ca-simir排斥力产生影响.在f2=0,0.000 1和0.001时,得到Casimir力的变化曲线,结果显示f2是抑制Casimir排斥力的.并且当f2很小时,Casimir力在较远距离处会重新回到吸引力,同时存在一个稳定的Casimir力平衡位置.Casimir effect is an observable macroscopic quantum effect. The paper we investigates the influence of the anisotropie material fill factor f2 on the magnitude and the po｜arity of Casimir force. It gives the change curve of permittivity and the permeability with the frequency when f2 = 0. 000 1, and finds that the Drude model will have an impact on the Casimir repulsive force. When f2 =0, O. 000 1 and O. 001, the change curve of Casimir force will have been obtained. The result shows that the fill factor fe is inhibition of Casimir repulsive force. In addition, the Casimir force will return to attractive force when the fill factor f2 is very small, and there is a stable equilibrium position of the Casimir force.
