A couple of kids actually modified a toy whistle from a box of Captain Crunch.

几个孩子实际上用一盒脆脆船长改造了一个玩具哨子。

I have to admit, I stole this last one and modified it a bit from my last tongue twister lesson from a year ago.

我必须承认，我从一年前的最后一节绕口令课上偷了最后一个并做了一些修改。

To do so they ran over 2,000 numerical simulations with the same exact initial conditions except for one difference: the distance between Mercury and the Sun,modified by less than a millimeter from one simulation to the next.

为此，他们在完全相同的初始条件下运行了 2,000 多次数值模拟，除了一个差异：水星与太阳之间的距离，从一次模拟到下一次模拟的修改不到一毫米。
