According to the formulae derived in this paper, the time sequence dependent relational graph exactly corresponding to the body of a DO-loop can be constructed under some given conditions.

对于满足给定条件的DO循环，根据文中导出的计算公式，可以精确地构造出与循环体相对应的时序依赖关系图。

youdao

Do nothing, close your loop and then down here do something.

不做什么，关闭你的循环，然后到这里做点事情。

youdao

What's the first thing I do in a loop?

And if I were to use that again, I'd just put it on your handout, I could go back and rewrite that thing that I had previously for finding the square roots of the perfect squares, just using the FOR loop. OK. What I want to do, though, is go on to-- or, sorry, go back to - my divisor example.

它可以是任意的集合,如果我又要去用这个方法的话,我会把它放在你们的课堂手册上的,我可以回过头去用FOR循环，重新写我们那个求平方数的程序，我想要做的是，是继续-哦抱歉,回到-我的除数那个例子。

Those buying guns from licensed stores and vendors are required to face a background check, but some purchasers buying guns from private sales at firearms shows and online do not need to do so, an exception often referred to as the gun-show loop-hole.

If Foursquare can subtly create brand associations and social media product placement in a non-obtrusive way, it may stand a chance, but to do so requires an OODA loop running at a much faster pace with a more diverse view of the marketplace.
