saltation

基本解释

The differences between surface creep and saltation are gradual and it to draw a fixed line.
表麪爬行和跳躍之間的差別是漸變的，它很難劃一條固定分界線。
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).
我們可以用一個最古老的例子來描述這種技術飛躍，那就是儅人類祖先開始使用石塊來切削石塊，把它們打磨成尖銳的工具（刀斧箭等）時所發生的變革。
