In eccentric septate channels the pores connecting adjacent compartments are shifted off-axis, either periodically or randomly, so that straight trajectories parallel to the axis are not allowed. Driven transport of a Brownian particle in such a channel is characterized by a strong suppression of the current and its dispersion. For large driving forces, both quantities approach an asymptotic value, which can be analytically approximated in terms of the stationary distribution of the particle exit times out of a single channel compartment.
在偏心的分隔通道中，连接相邻隔室的孔会偏离轴心周期性或随机地移动，因此不允许沿轴的直线轨迹。在这种通道中，布朗粒子的驱动输运表现为电流的强烈抑制和弥散。对于大的驱动力，这两个量都趋近于一个渐近值，可以根据粒子从单个通道隔室中离开的时间的稳态分布来解析近似。
