In the second part , a method studying stochastic transition which is the master equation method is introduced , and explicit solutions of velocity v and diffusion constant d of the steady state are obtained when a particle hops among a dimensional and periodic n states 第二部分介紹了一種研究隨機(jī)躍遷的方法?主方程方法,著重推導(dǎo)了粒子做一維周期性n態(tài)隨機(jī)躍遷時(shí)達(dá)到穩(wěn)態(tài)的速度、擴(kuò)散系數(shù)的一般表達(dá)式。
