论文摘要
研究了限制在3D(三维)瓦楞纸上与高斯噪声的活性颗粒的转运现象。垂直于对称轴的大噪声强度适合沿轴的扩散和电流。广义的共振转运现象出现,噪声强度增加与对称轴平行。平行于轴的大噪声强度可以抑制扩散。扩散系数的最大值随极角噪声强度的增加而具有最大值。出口是参数F的最佳值,从而导致最大运动速度。大F对扩散有好处。传输反向现象出现,并增加了通道参数ε和δ。太大或太小的ε和δ值可以抑制扩散。
The transport phenomenon of active particles confined in 3D(three dimensional) corrugated confined channel with Gaussian noises is investigated. Large noise intensity perpendicular to the symmetry axis is good for the diffusion and current along the axis. The generalized resonance transport phenomenon appears with increasing noise intensity parallel to the symmetry axis. Large noise intensity parallel to axis can suppress the diffusion. The diffusion coefficient has a maximum with increasing polar angle noise intensity. There exits an optimal value of parameter f that result in maximum movement speed. Large f is good for the diffusion. Transport reverse phenomenon appears with increasing channel parameter ε and Δ. Too large or too small values of ε and Δ can suppress the diffusion.
