摘要：
Small flagellated bacteria cannot swim in a straight course due to rotational Brownian motion. By using Langevin equation and rotational diffusion equation we develop a model for the flagellated bacterial motion; thus, the model includes the rotational Brownian motion. Our model shows that the rotational Brownian motion is more significant at smaller turn angle during a tumble. It is also compared with experiment data.
