时差N小时 无糖可乐和含糖可乐(上)

Here's an at-home experiment you can try.

你可以在家做这样的实验。

Take a can of "classic" Coca-Cola and a can of Diet Coke, and without opening either one submerge them in water.

把没打开过的两听可乐放在深槽或者高桶中，

A deep sink or a bucket will do the trick.

里面的水淹没两听可乐，

You'll find the can of Diet Coke rises to the top, while the Classic Coke stays sunk. Can you guess why?

你会发现无糖可乐浮在水面;而含糖可乐却沉下去了。你能猜到原因吗?

The answer lies in the chemical contents of the Diet Coke-in fact, in the very distinction that makes it "Diet".

奥秘就在于无糖可乐的成分，这也是“无糖”的原因。

Although their ingredients are otherwise similar, Diet Coke is not made with real sugar:

虽然，无糖可乐和普通可乐的成分很相似，

instead, the makers¹ of Coca-Cola products have replaced the sugar with a synthetic² chemical called Aspartame.

无糖可乐中添加的并非真正的糖，而是一种做“阿斯巴甜”的合成化学物。

Aspartame, which is commonly known as Nutra sweet, is a kind of substitute sugar-intended to mimic³ the distinctive⁴ taste of sugar without carrying the associated calories.

“阿斯巴甜”是一种常见的代糖甜味剂，不含糖的热量却有糖的甜味。
