研究了由完全不对称简单排斥过程(TASEP)和两通道简单排斥过程(SEP)构成的周期一维排斥过程。TASEP和SEP相互竞争。在蒙特卡罗模拟的补充下，进行了平均场分析。改变电流分裂参数θ、扩散率d1(或d2)和全局粒子密度Np，研究了相图、典型密度分布和电流图。
This paper studies the periodic one-dimensional exclusion processes constituted by totally asymmetric simple exclusion process (TASEP) and two-lane simple exclusion processes (SEP). TASEP and SEP compete with each other. Complemented by Monte Carlo simulations, mean-field analysis has been performed. Varying current splitting parameter θ, diffusivity rate D1 (or D2) and the global particle density np, we have studied phase diagrams, typical density profiles and current diagrams.
