Myosin; biased Brownian movement model; efficiency of the molecular motor

肌球蛋白；偏布朗运动模型；分子马达的效率

The biased Brownian movement model is one of the important ways to describe the molecular motor walking along the track. The deficiency of this model is that motor is not capable of producing a sufficiently strong force and the efficiency of motor is very low.

偏布朗运动模型是描述分子马达沿轨道运动的主要理论之一，此类模型的不足之处是不能产生足够强的力，其效率不高。

The long memory of time series array firstly was found by Hurst in 1951, and then was established mathematical foundation by introducing fraction Brownian movement and conception of fractal by Mandelbrot.
