很多的孩子都喜欢到“麦哥”那儿，啃上一个Sandwich来填饱自己的肚子。4月10号的纽约时报登了一篇关于Sandwich的文章，想知道内容吗？
A:是关于垃圾食物的吗？
N:不是拉，是科学家居然开始用数学方程来解密Sandwich，信不信由你啊！

The Perfect Bacon Sandwich Decoded: Crisp and Crunchy

Should it be slithery or scrunchy, glutinous or grilled? The answer, British scientists say, may be divined by a formula:
N = C + {fb(cm) · fb(tc)} + fb(Ts) + fc · ta.—————这就是大名鼎鼎的sandwich方程！

好的三明治是需要用0.4牛顿的力产生0.5分贝的香脆声的！其中公式中的N就是吃三明治用的力啦！fb是关于火腿形状的函数，fc是关于调料或填充物的函数，ts是制作时的温度，tc是制作时用的时间，ta是添加调料的时间，cm表示制作的方法，c代表吃火腿的力。真的好麻烦啊！

That is the scientific answer to the question: what makes the perfect bacon sandwich?

And, no, it is not April 1.

Researchers at Leeds University（利兹大学，听说过英超的利兹联队吧，想了解这个学校可以看看这个网址吧http://www.leeds.ac.uk/） spent more than 1,000 hours testing 700 variants on the traditional bacon sandwich, which many Britons refer to as a bacon butty （不要奇怪英国人就是这么叫三明治的）(eschewing the term sandwich, said to have been coined to honor the fourth Earl of Sandwich’s habit of eating meat between slices of bread around 1762).

For Britons, butties come in a variety of guises — chip butties (French fries between slices of bread), crisp butties (ditto with potato chips) or even sugar butties, which are self-explanatory. None are viewed as especially healthful.
