也就是说只有在适当的温度和跃迁速率下，才会有较大的流，说明几率流对温度和跃迁速率都是有选择的。 |

计算结果表明，在温度很低或很高时，定向运动的几率流都趋于零；在适当的温度范围内，对于某一确定的跃迁速率，总存在一个几率流的最大值，而且随着速率的增加相应于最大几率流的温度值升高。 |

本文第一章，我们将捕食者种群分为未成年与成年两个阶段，并且假使只有成年个体捕食食饵，而未成年个体不捕食食饵；同时假设捕食种群中未成年个体成熟为成年个体的转化率是未成年种群密度的函数；建立了具有阶段结构的捕食者-食饵模型。 |

我们认为马达在不同状态之间的跃迁不再局限于某些固定的跃迁点，也不是在各个位置都是等几率的，而是发生在某些点附近的一定宽度范围内，用跃迁宽度这一特征量表征跃迁范围的大小，能够较好地说明分子马达的动力学行为。 |
