大部分形状记忆合金只能“循环”(或称改变形态)有限次数，之后材料就会疲劳了。

Most shape memory alloys can only "cycle" (or change form) a limited number of times before the material gives out.

换句话说，大部分你的网站流量来自于那些每月只接收有限次数搜索的冷关键词。

In other words, much of your search traffic comes from little words that receive only a handful of searches each month.

前面提到flash设备属于耗损品：在变成坏块以前，可以执行有限次数的反复的Erase操作(因此必须由坏块管理进行标记)。

Recall that flash devices are consumable parts: You can perform a finite number of Erase cycles on each block before the block becomes bad (and must therefore be tagged by bad block management).

Do the following a bunch of times, but a finite number of times which might be useful.

按照下面重复若干次，有限次数就足够了，这很有用。

So unlike Scratch where you pretty much had to say "repeat" ten times or whatever, or forever where it's just "forever" with for loops, -- can you actually specify a finite number of iterations -- and as I learned 15 years ago, finite is important.

所以不像Scratch，你大致上需要用,“repeat“10次或更多，或者需要不断地使用当它,是死循环时，你们能够指定出一个有限的迭代次数-,像我15年前学的，有穷的是重要的。
