In this dissertation , two particular cooperative behaviors of the molecular motors in muscle isotonic contraction are introduced : ( l ) no attached cross - bridges work at the same tempo , the working process is not affected by the environment ; ( 2 ) no attached cross - bridges work at the same tempo , and the working rate is proportional to the very velocity of thin filament in the contraction
运用能量守恒定律，本文探讨了分子马达间的两种特定的协作行为： (一) n _ 0个分子马达同步的工作，并且其工作过程与外部的环境无关。 (二) n _ 0个分子马达同步的工作，但其工作的时间t _ ( on )与细纤丝的速度v成反比，即t _ ( on ) = a / v ，其中a是一个单位量纲因子。
