ECR等离子体系统中粒子沿微管传输的研究

摘要

建立了一个等离子体系统内粒子传输模型,研究在一个ECR等离子体系统中,如何通过某些环境参数的变化来使得沿微管表面传输的粒子产生净流动.在此模型中,在非平衡热涨落、磁场作用和外场力等因素的综合作用和共同驱动下,得到一个净几率流J,当这些因素彼此竞争彼此作用时,J随着某个参数的改变而发生方向改变.此外,通过理论模型的计算,得到了J关于不同参数的相关函数.%A model is established to study the transportation of particles along the surface of a microtubule, 'caused by some environment parameters in an ECR plasma system. In this model, the thermal fluctuations, the magnetic field and the external force are three driving factors for obtaining a net probability current /. When the three driving factors compete with each other, the current J may reverse its direction in view of the variation of some parameter. The current J is also obtained respectively as the function of different parameters.
