摘要
阐述了鞭毛细菌的游动特性和溶液中pH梯度场的形成原理,借助COMSOL Multiphysics软件在电极施加电压情况下对溶液中电势分布求解。介绍了一个实验平台,以验证pH场的形成,并设计不同电极形状的实验装置用于实验和仿真的结果比对。通过实验中pH场分布情况与仿真电势分布结果的对比,得到了pH梯度场与外加电场对应的结论。
Firstly, the article investigates the swimming characters of flagellar bacteria and principle of forming pH gradient in solution. Then COMSOL Multiphysics software is used to solve the models of electric potential when electrodes are applied in solution. Secondly, a device is introduced to complete the experiment of the study. To testify the simulation result with experiments, another experiment using different electrode shapes is investigated. Finally, discussion is made： distribution of pH gradient in experiment is found in correspondent with simulation results, which means pH gradient in solution is related to voltage exerted on the electrodes.
