Then we investigate two particular cooperative behaviors of cross bridges in muscle isotonic contraction ( in which the extern load F is constant):( 1) n 0 attached cross bridges work at the same tempo, the working process is not affected by the environment;

在此基础上，考察了横桥分子间的两种协作行为：（1）n0个处于接触状态的横桥分子同步的工作，其作功过程与外界影响无关；
