简言之，NOCYCLE防止递归进入循环。
In short, NOCYCLE prevents the recursion from entering a cycle.
可见，递归函数与循环有很多类似之处。
As you can see, recursive functions and loops have quite a bit in common.
通常情况是函数内包含了过多的循环(不是在循环中执行了过多的内容)，太多的递归，或者只不过是太多不相干但又要一起执行的操作。
Usually this means there's too many loops (as opposed to too much happening in a loop), too much recursion, or simply too many different operations being performed.
将一个常见的循环转化为递归函数。
注意递归的使用，避免完全while循环。

无论是在c、XSLT中，还是在Scheme中，都应用了使用递归代替循环。
Replacing loops with recursion, whether in c, XSLT, or Scheme, takes some getting used to.
这便是haskell没有while或for循环的原因，我们的替代方案是使用递归。
That's why there are no while loops or for loops in Haskell and instead we many times have to use recursion to declare what something is.
函数式编程中，传统语言中用循环完成的多数任务都可以使用递归来完成。
In functional languages, most tasks that are accomplished with loops in traditional languages are instead accomplished with recursion.
注意，此版本甚至可以在循环自身中使用递归，两次调用循环本身，一次用于对列表左手边的内容进行排序，另一次对列表右手边的内容进行排序。
Notice that this version even makes use of recursiveness in itself, calling itself twice, once to sort the left-hand side of the list, and once again to sort the right-hand side of the list.
无论是太多的循环、递归还是其他的什么，你现在应该知道如果处理类似的情况。
Whether there be too many loops, too much recursion, or just plain too much going on, you now know how to deal with each.
当我们将循环转化为递归函数时，递归调用是函数所做的最后一件事情。
When we converted our loop to a recursive function, the recursive call was the last thing that the function did.
因此，只有在非常复杂的大量使用循环和递归调用的应用程序中，才需要考虑这种潜在的影响。
Therefore, the potential impact is a factor only in complex applications where iterations and recursive invocations are heavily used.
在表1中了解循环的特性，看它们可以如何与递归函数的特性相对比。
Take a look at the properties of loops and see how they compare with those of recursive functions in Table 1.
注意，在循环的结尾处，我用一个比上次大1的参数递归地调用同一个函数，以实现循环的迭代。
Note at the end of the loop that I recursively call the same function with an argument that is one greater than the previous, implementing the iteration of the loop.
通常，函数语言会避开while循环，因为while实现的大多数操作都可以使用递归来完成。
Normally, functional languages eschew the while loop, because most of what while does can be done instead with recursion.
而在Erlang中不需要使用循环，因为尾递归函数会被自动优化在固定的空间中运行。
In Erlang there is no need for loops because tail recursive functions are transparently optimized to run in constant space.
根据Wikipedia：递归（拉丁语recurrere->currere =run和re =return）是以自相似性的方式循环某些项的过程。
According to Wikipedia: Recursion (lat. recurrere -> currere = run and re = return) is the process of repeating items in a self-similar way.
几乎在任何情况下都可以用循环替代递归。
