saltation

基本解释

The differences between surface creep and saltation are gradual and it to draw a fixed line.
表面爬行和跳跃之间的差别是渐变的，它很难划一条固定分界线。
The oldest example of such a technical saltation was when our hominin ancestors began using stones to fashion other stones into sharp tools (axes, knives, and arrows).
我们可以用一个最古老的例子来描述这种技术飞跃，那就是当人类祖先开始使用石块来切削石块，把它们打磨成尖锐的工具（刀斧箭等）时所发生的变革。
