将系统利用非平衡涨落能量做功，看作是布朗马达受到内外噪声作用的结果，并建立相应的含阻尼、双噪声的扩散模型．通过解析计算和数值模拟，在一维惯性锯齿势中，阐明了乘性噪声驱动布朗马达定向运动的机理，分析了黏滞阻力对定态流的影响．作为应用，解释了单个马达蛋白梯跳运动的实验现象．
Using the unbalanced fluctuation energy as a function of the system, the system is treated as a result of the Brownian motor being affected by internal and external noise, and a corresponding diffusion model with damping and double noise is established. By means of analytical calculation and numerical simulation, the mechanism of multiplicative noise-driven Brownian motor directional movement is clarified in the one-dimensional inertia sawtooth potential. The influence of viscous resistance on the steady state flow is analyzed. As an application, the experimental phenomenon of single motor protein ladder jump was explained.
