摘要：

The transport properties of one-dimensional (1D) systems have been studied theoretically. Contradictory experimental results on molecular transport in quasi-1D systems, such as zeolite structures, when both diffusion transport acceleration and the existence of the diffusion mode with lower particle mobility (single-file diffusion (< x(2)> similar to t(1/2))) have been reported, are consolidated in a consistent model. Transition from the single-file diffusion mode to an Einstein-like diffusion < x(2)> similar to t with diffusion coefficient increasing with the density has been predicted to occur at large observation times.
