碩士 === 國立成功大學 === 工程科學系碩博士班 === 97 === There are many researches regarding using fluctuation analysis to explain the movement of molecular motor. However there are not so many studies being presented by considering the condition of nonuniform temperature. Therefore provide a fluctuation analysis with the motor movement which is running under nonuniform temperature. The Fokker-Planck equation is the governing equation in this paper,it can be used to slove the probability and the probability fiux and it also can be used on calculating working model with potential energy switches between on and off state by Robust numerical algorithm in the reference[11]. This paper used MATLAB7.0 to calculate the equations and the numerical algorithm to analyze.The behavior of Brownian motion in the case of coupling a periodic potential to a nonuniform temperature foeld is further investigated.The results of this study are highly consistent with this of previous studies for the reference[6].Discuss the average velocities and randomness of Brownian motions.By changing the molds of amplitude,temperature difference and particle moves distance to discussthe effects of molds which are average velocities and randomness to Brownian motor kinetic.
