纳米管道中离子分布模型的研究

Study on ionic distribution in the nanochannel

基于纳米管道内离子浓度与电势变化的规律,针对泊松-玻尔兹曼模型的几种改进方法进行比较说明,并提出使用的限制条件。通过对理论的研究分析,泊松-玻尔兹曼的分析解很难获得,而仿真的数值解却容易求得,这个结论更有利于进一步的理论研究。

Based on the variation of ionic concentration and electric potential in the nanochannel, several improved Poisson- Bohzmann methods were proposed for illustrating the limiting condition and comparing the model with others. The analysis of theoretical research shows that the numerical solution, different from the analytical solution, can be easily obtained by using the improved Poisson-Bohzmann method. This resuh contributes to further theoretical study.
