摘要: 分子马达是一类将化学能转化为机械能的微小机器. 对二维模型的研究表明, 非保守力在体系与外界能量交换中发挥重要作用. 四态模型较好地反映了马达力学化学过程的各个状态及相应的构象变化. Motor protein is a kind of small machines that convert chemical energy to mechanical works. It is revealed from the study of the twodimensional model that the non conservative impulsive force plays a significant role in the exchanging process of energy. A four state model characterizing the coupling of mechanical and chemical processes of molecular motor is also discussed.
