brownian motor 中文意思是什麼
brownian motor
解釋
布朗馬達-
The thesis includes three parts : firstly, previous study and latest advance of molecular motor in biology are outlined, including myosin ' s and kinesin ' s construction and function, the latest advance of molecular motor in constructional biology ; secondly, the latest advance of molecular motor in physics is reviewed, including the general view of brownian motor and two examples of molecular motor, one being related to two kinds of flashing potention energy, the other being related to electronical bipole ; and finally, the model on unidirectional motion of molecular motor is in detail come up with, and especially, the interact ion between two heads is taken into account, followed by the construction of langevin equation and fokker - planck equation involved in the model. by using solutions of fokker - planck equation, unidirectional motion mechanism of molecular motor is analyzed
本文內容包括：首先綜述生物學領域分子馬達研究的最新進展，內容安排為：肌球蛋白的結構和功能，驅動蛋白的結構和功能，肌球蛋白和驅動蛋白定向運動機制的結構生物學方面的最新進展；其次綜述並分析了當前研究分子馬達定向運動機制的幾種物理模型，內容安排為：分子馬達運動的基本觀點和建構模型的一般方法，勢壘的兩態漲落誘導的分子馬達運動模型，分子馬達定向運動的偶極子模型；最後討論雙頭相互作用的分子馬達模型，內容安排為：先詳細論述模型的構建，再建立langevin方程和fokker - planck方程，接著用差分的方法求解出fokker - planck方程的解，然後分析和研究分子馬達定向運動的機制。 -
In the scale of molecule, we cannot ignore the random collision between liquid molecules and motor. so the movement of motor has the features of brownian movement
在分子水平的尺度上，細胞液中的液體分子對馬達的無規碰撞已經不能忽略，因此分子馬達的運動具有布朗運動的特徵。 -
We can take molecular motor as a brownian particle in the case of ignoring the conformational changes. the interaction between motor and microtubule can be described by a special potential function and the effect of the environment can be simplified as a noise
在不考慮分子馬達構象變化的情況下，通常把分子馬達抽象為布朗粒子，用一個特定的勢函數來表示軌道與馬達的相互作用，環境的影響可以簡化為特定形式的噪聲激勵。 -
When the temperature t is smaller, even if there is the slope of the effective potential, most brownian particles ( motor proteins ) can not span the potential
（ 3 ）幾率流不僅與有效勢的整體傾斜的斜率有關，同時還與有效勢的勢壘高度有關。
